The reality of Canada's new regulations on carbon emissions from coal-burning power plants

On Friday, the Canadian Minister of the Environment announced new emissions rules for coal plants which supposed encourage a shift to effective capture and storage of carbon. And, yes, you may be right to be suspicious about any new regulations announced on a Friday afternoon in the middle of August, when the vast majority of Canadians are planning for the weekend and ignoring the news. According to Minister Peter Kent:

These proposed regulations take into account the fact that many electricity facilities across Canada are old and need to be replaced soon. We're acting now to ensure that power companies understand today, the rules that will affect the new investments they have to make tomorrow. It allows for an orderly process - the bedrock of certainty.

The scant news coverage pointed out that the new standards only apply to plants built after July 1, 2015, thus exempted some proposed new coal plants.

That includes Calgary-based Maxim Power Corp.'s contentious proposal for a 500-megawatt expansion at its HR Milner facility, which received final approval from the Alberta Utilities Commission earlier this month and must be built by July 31, 2015 - a condition of the go-ahead (Calgary Herald)

The actual regulations may prove to be even more controversial. I encourage interesting followers of Maribo to read the text of the regulations (pdf from Environment Canada) and provide their interpretation in the comments.
In my reading of the reults, I found what I think, but I could be mistaken, are very large loopholes which could prevent any real reduction in carbon emissions from coal-electricity generation until at least 2025.

First, here's the actual emissions limit, and I'll leave the intrepretation of the number to the readers:

3. (1) A responsible person for a new unit or an old unit must not, on average, emit with
an intensity of more than 375 tonnes CO2 emissions from the combustion of fossil fuels in the
unit for each GWh of electricity produced by the unit during a calendar year.

Then it gets complicated:

(b) a declaration that includes the following statements:
(i) that, based on the economic feasibility study referred to in paragraph (c), the unit,
when operating with an integrated carbon capture and storage system is, to the best of
the responsible person’s knowledge and belief, economically viable, and
(ii) that, based on the technical feasibility study referred to in paragraph (d) and the
implementation plan referred to in paragraph (f), the responsible person expects to
satisfy the requirements referred to in section 9 and, as a result, to be in compliance with
subsection 3(1) by January 1, 2025;

So, again, if I am reading this right, you can gain an exemption from the regulations if you are able to conduct a study showing that the CCS system will be capable of meeting the new emissions regulation by 2025.

Putting this all together: 

1. Any coal plants built before July, 2015 which have not reached the end of their useful life [ed - see comment #1] are exempt. Given the expected shift towards natural gas in the next few years, it is entirely possible that the regulations will not end up applying to any coal-burning plants unless they are old units, as all the other coal-burning plants will be "grandfathered" in. [ed - fair?]

2. Any coal plants built after July, 2015 are exempt until 2025 so long as it is technologically possible to install a CCS system by 2025. Therefore, CCS systems are unlikely to be operating at any large scale coal plants in Canada for another 15 years. This delay may reflect the technological challenge of CCS or the values of the current government, or both.

Hopefully, I'm wrong.

Canada's sham of a federal climate policy

In yesterday's Globe and Mail, Marc Jaccard wisely pointed out the gaping flaws in the Canadian pledge to reduce greenhouse gas emissions by 17% by 2020. The pivot point is a proposed new coal-burning power plant in B.C.Alberta:

Stephen Harper can’t allow new coal-fired electricity plants to be built, such as the one Maxim Power is proposing in Alberta, and achieve his promise to reduce Canadian greenhouse-gas emissions 17 per cent by 2020. As a researcher of energy-economy systems, I say this with virtual certainty. I also know that any scholar in my field would agree with me, and that the Prime Minister’s expert advisers would tell him the same thing.

There are two stories here. The first is that Canada has made many emissions pledges but repeatedly failed to enact any plan to meet those pledges. This is not a partisan issue. It happened under majority and minority Liberal governments, and it is happening under minority and now majority Conservative governments:

In 2007, Mr. Harper committed Canada to a 2020 target for greenhouse-gas reduction but hasn’t implemented policies that would achieve it. Like Mr. Chrétien, Mr. Harper must know his scant policies will fail. Recently released internal government documents show he’s receiving information from civil servants telling him his current policies are not transforming the energy-economy system in the direction he’s promised.

The second story is that climate policy is ineffective and meaningless without short-term and long-term goals. With no short-term emissions target, we end up delaying shifts in the energy infrastructure, and in the case of the coal-burning power plant, committing to future emissions which make meeting the long-term goal more difficult if not impossible. Jaccard praises the approach taken by the Campbell government in B.C.:

In 2007, then-B.C. premier Gordon Campbell also committed to a 2020 emissions reduction target. But to convince people of his sincerity – especially after two decades of climate policy failure by all Canadian governments at all levels – Mr. Campbell acted very differently. First, he got an independent body to set interim targets for 2012 and 2016, so people would know within a political time frame if he were on track to keep his promise. Second, he asked his advisers what investments needed to happen in 2007, and every year thereafter, to meet the 2020 target. On that basis, he immediately implemented a zero-emission electricity policy, which caused the cancellation of two proposed coal-fired electricity plants that had signed preliminary supply deals with BC Hydro.

Granted this approach is certainly easier, and more politically palatable, in a jurisdication where hydro-power is abundant. Nevertheless, it is a good model to follow.

The complexity of climate change policy

Buried in a couple recent news stories, which themselves were buried by the news of the debt standoff in the U.S.,  were a couple fascinating nuggets that reveal a lot about how climate change mitigation policy does, and does not happen.

One is an agreement to raise fuel efficiency standards in the U.S., which will presumably also become the rule in Canada. The... greement to that vehicles sold will average 54.5 mpg by 2025, although with loopholes related to measurement of efficiency, the actual average will be more like 43 mpg.

Why did it happen? (NY Times):

It is an extraordinary shift in the relationship between the companies and Washington. But a lot has happened in the last four years, notably the $80 billion federal bailout of General Motors, Chrysler and scores of their suppliers, which removed any itch for a politically charged battle from the carmakers...

The new mind-set in Detroit has been helped by some give and take on the government’s side. G.M., Ford and Chrysler pressed for less onerous mileage goals for their profitable pickup trucks and got them. And the administration agreed to revisit the new requirements halfway through their course, with the possibility of adjusting them. In the end, though, Detroit was faced with an undeniable political reality: there was no graceful way to say no to an administration that just two years ago came to its aid financially.

The auto bailout as climate policy: investing in the companies provided some leverage in the battle to reduce emissions from passenger vehicles. Was the Obama administration prescient here, knowing that there were little odds of carbon tax on fuel? More likely, the U.S. government was merely taking advantage of an opportunity to use some leverage to push an emissions reduction effort. Of course, the idea of "nationalizing" companies in hopes of enforcing a climate change policy would cause the "Tea Party" to self-combust.

The other example is the Alberta government's approval of a carbon capture and storage project (Globe and Mail):


Calgary-based Swan Hills Synfuels LP aims to use an unproven method, coal gasification, to reach 1.4-kilometre-deep coal deposits in central Alberta, convert them to gas underground, capture the emissions before they ever see daylight and use the gaseous coal to run a power plant. The new plant would serve a whopping 300,000 homes while producing one-third the emissions of a similarly sized regular coal plant – or about the same carbon output as a natural-gas plant. Because the project will divert 1.3 million tonnes of carbon dioxide a year – providing the cost certainty of coal and environmental performance of natural gas – Alberta coughed up $285-million for the $1.5-billion development.

Now, investment in a CCS project in Alberta is not a huge surprise, especially considering the particular plant can aide in oil recovery. But then there't this nugget:

Industry members, politicians and academics said provincial funding is necessary because there’s little incentive to reduce emissions. CCS is “viable, but it comes at a cost,” said Don Lawton, a University of Calgary geophysicist who studies CCS. “But until there’s a price on carbon, it’s an expense that has to be borne by somebody.” Mr. Lambert said the project would die without provincial money. “I don’t think I could deliver the returns investors would need to put their money up,” he said.

So the CCS projects go ahead, but solwly, and at great expense to the province of Alberta because of the lack of a federal carbon price, which was strongly opposed by politicans from Alberta. Unlike the automobile case above, pricing carbon is critical to making CCS work.

Organic vs. conventional agriculture

The new Scientific American blog Science Sushi dispels some myths about large-scale organic agriculture. Here's one example:


Some people believe that by not using manufactured chemicals or genetically modified organisms, organic farming produces more nutritious food. However, science simply cannot find any evidence that organic foods are in any way healthier than non-organic ones – and scientists have been comparing the two for over 50 years.

Better for the environment does not necessarily mean better for you (or for the climate). Not that the environmental benefits are clear either:

Yes, organic farming practices use less synthetic pesticides which have been found to be ecologically damaging. But factory organic farms use their own barrage of chemicals that are still ecologically damaging, and refuse to endorse technologies that might reduce or eliminate the use of these all together.

It's worth a read.

Is it time to start holding virtual conferences? The case of the International Coral Reef Symposium

The only thing hotter than the U.S. and Canada (east of the Rockies!) in the past week was the discussion on the Coral-List, the NOAA-managed read by pretty much anyone that does research related to coral reefs, about the cost of attending next year’s International Coral Reef Symposium. The ICRS is THE meeting in the world of coral reef research. Thanks to the Olympian once-every-four-years timing, attendance is, I’d argue, as mandatory as it comes in the sciences. Miss an American Geophysical Union (AGU) meeting, and you can attend another in six or twelve months. Miss an ICRS, and, well, you’ve got four full years to train for the next one.

The full week registration fee for the meeting has been set at AU$960 - AU$1250, depending on membership in the scientific society and the date of purchase. While registration fees of $1000 or more are not unheard of for scientific meetings in other branches of research, like say medicine, the price is extraordinary for the natural sciences, and especially for a sub-field in which many of the researchers are based in developing countries. Naturally, people from small NGOs in SE Asia to large academic instituions in North America are upset and stating that they will not attend.

Shocking as they be to many, the real story is not the registration fees. The real story is is the travel.

In addition to timing, the ICRS shares a logistical challenge with the Olympics. There is no optimal site for the event. Coral reefs are found throughout the tropics and subtropics, and that is excluding the cold water reefs in places like our own BC coast. Coral reef researchers are even more widespread, with scientists dotting every continent save Antarctica (I think - anyone at McMurdo care to correct me here?). No matter where the ICRS is held, be it Florida (2008), Okinawa (2004) or Bali (2000), a majority of top researchers in the field will have to travel long distances to attend. That means a lot of money – I estimate a weeklong trip to Cairns for the meeting from this part of the world could cost CAN$3500-4000 with registration. Moreover, that means a lot of greenhouse gas emissions. All for a scientific meeting about an ecosystem which many argue is existentially threatened by climate change and ocean acidification.

Hence the question on many people’s minds. Should the ICRS go virtual?

Of any scientific conference, there are certainly strong arguments for making the ICRS virtual: no optimal location for the meeting, cost being a significant barrier for many potential participants, travel restrictions being problematic (e.g. Middle East researchers requiring special visas for places like the U.S. and Australia), and of course the subject of conference being sensitive to atmospheric CO2. A counterargument is that the meeting is held only once every four years, in part for some of these very reasons, so rather than make ICRS virtual, other annual meetings should go virtual and adopt an Olympic schedule for the “live” meetings. A compromise first-step would be a hybrid meeting in which people had to option to participate "live" or online.

Society has adapted quickly to tectonic shifts in the way we communicate. Virtual conferences, which so many disdain for missing that personal connection of a live meeting, will become perfectly normal to us at some point in the future, just as e-mail, web browsing, Google Earth, Facebook, and Twitter have. It's a question of when, not if.

My question is: Which scientific society is willing to be the early adopter?

Climate impact of different foods

Earlier this week, the Environmental Working Group, a research and lobby group in DC, released a report on the “environment” and "health" impact of different foods. It found that lamb is the worst offender, followed by grain-fed beef, pork, cheese and farmed salmon.

The report was brought to my attention by a writer at the Huffington Post, who subsequently published this story which includes thoughts on the report a number of outside experts on the issue. I commented on the climate impacts of feed production and the logic of farming top-of-the-food chain fish like salmon, both issues that have been discussed frequently here at Maribo.

Here's a more complete list of my thoughts upon examining the short report:

1. “Environmental” impact or “health” impact can be very different than “climate” impact. For example, I’d expect lamb to be much lower on a list based purely on greenhouse gas emissions (i.e. per gram of food produced). I can't comment on "health" impacts as it is not my area of expertise.

2. What I call the “land use cascade” is potentially the largest contributor of greenhouse gas emissions from food production, but also the hardest to calculate. That’s why GHG emissions from dairy relative to beef cattle tend to be overestimated (more methane from dairy cattle, more land required to grow feed for beef than dairy products). It’s also why any study like this should have large positively skewed error bars.

3. All meat is not created equal in terms of greenhouse gases. Grain-fed beef is far less efficient than pork, which is again far less efficient than poultry.

4. If your food choices are motivated purely by concern about greenhouse gas emissions, eating less grain-fed beef is more important than eating locally.

5. Historically-speaking, we are just starting to develop industrial-scale farming of fish, as discussed in the recent Time cover story. Farming the ocean is, in a sense, thousands of years behind farming on land. Right now, many of the choices we are making are, as I put bluntly in the Huffington Post story, “stupid”. Cattle are logical choice for farm animals. They eat grass, so they are only one step away from the sun. Salmon are much higher up the food chain. That’s why many of us say farming salmon is like farming wolves or tigers – you need the whole ecosystem to support the one salmon.

Eliminating the US corn ethanol subsidy is no panacea

One possible casualty of the endless U.S. budget fight may be the federal subsidy for corn ethanol production. There's been a lot of quiet, and some not-so-quiet, cheering from the environmental community, based on the premise that eliminating the subsidy will lessen nutrient pollution from growing so much corn.

In reality, cutting or repealing the 45-cents-per-gallon ethanol tax credit is unlikely to have much of an effect on planting decisions. As a recent article in the NY Times nicely explained last week, the subsidy is, at this point, unnecessary. Between laws requiring blending of ethanol into gasoline, the federal ethanol mandate, the tariff on imports, the size of the ethanol production industry, and the high price of corn, there's already enough incentive to maintain the status quo in corn production and corn ethanol production.

There are certainly good reasons to eliminate the subsidy. No one should pretend that doing so will solve of the problem of nutrient levels in the Mississippi River and the Gulf of Mexico. That is a far greater challenge.

Housekeeping and new links!

I wanted to draw people's attention to the updated list of links on Maribo. I've added a few new links which I learned of at the terrific Google Science Communication Fellows workshop last month: Alan Townsend's new blog State Factors, Jon Koomey's blog and Eugene Cordero's effort Green Ninja.

Maribo itself is likely to change in the next few months. I'm considered new formats for the blog, and also alternative approaches to online outreach about climate issues. Feel free to pass along any suggestions!

Farming the sea

The cover story in this week's issue of Time Magazine tackles the pros and cons of farming fish, a subject that gets suprisingly little solid media coverage in North America. Bryan Walsh's article does a decent job covering the decline of the world's fisheries, and the need for solutions. But like so many articles on the subject, it buries what should be the lede:

Especially troubling, many of the most popular farmed species are carnivores, meaning they need to be fed at least partly with other fish. By one count, about 2 lb. of wild fish ground up to make fish meal is needed on average to produce 1 lb. of farmed fish, which leaves the ocean at a net loss.

I've written about this before: A substantial proportion of the wild harvest is used to maintain marine aquaculture of carnivorous species like salmon. It is wildly inefficient, the marine equivalent of farming wolves rather than herbivorous cattle. This is why many experts conclude that the future for pescetarians is probably the blander, lower-on-the-food-chain species like tilapia and catfish.

In coverage of aquaculture, we tend to focus on the sexier and scarier subjects: pollution from farms, genes mixing with the wild population, PCBs in farmed salmon, etc. Certainily, no doubt, these are all serious concerns (except perhaps the PCBs). But the feed-to-fish ratio is the very core of the matter; if you get less fish protein out than you put in, aquaculture doesn't make a heck of a lot of sense.

Walsh gets to this central dilemma in the second half of the article:

When producers began raising fish intensively, they picked species that people like to eat: salmon and sea bass. But those species are high on the food chain, and raising them on a farm is a bit like trying to domesticate tigers. [ed - nice. I always say wolves] The aquaculture industry has gotten better at replacing fish meal with plant-based feed, but not fast enough. You're not feeding the world sustainably if you need to remove the base of the marine food chain to do it. 

The solution that many propose is expanding the use of plant-based products in fish food. That brings it's own complications. For one, salmon certainly didn't evolve eating soymeal, cornmeal or wheat, so shifting to a majority plant-based diet will likely involve further genetic engineering, which has supporters and detractors. 

And second, feeding plant products to fish would add another player in the struggle for the world's productive croplands. 

Forget food vs. feed. Or food vs. fuel. In the future, it will be a battle of the 4 Fs:  food vs. feed vs. fuel vs. fish.

Canada upsets other countries at climate negotiations

Though news of Canada's selective emissions reporting drew little attention here at home, other countries took notice. From Post Media News:

OTTAWA — Foreign diplomats bombarded Canadian climate change negotiators with questions Thursday in Bonn, Germany, as they challenged the Harper government's transparency and policies to fight global warming.


In the wake of media coverage highlighting missing and conflicting information in an Environment Canada submission to the United Nations, officials from Australia, China, Lebanon, the United Kingdom and the Philippines questioned government policies regarding fossil fuel subsidies and the Alberta "tarsands," a lack of investment in clean energy and the scientific evidence used to determine its greenhouse gas emissions target...


Representatives from other countries pounced on Canada after Michael Keenan, an assistant deputy minister at Environment Canada, delivered a presentation suggesting that the government was showing "significant ambition" in its proposal to crack down on greenhouse gas emissions.


But his presentation appeared to generate more questions than answers.


"I was also struck that the colleague from Canada didn't refer to the tarsands issue or at least only once in passing," said Peter Betts, the lead European Union negotiator and a director at the United Kingdom's Department of Energy and Climate Change, during the session. "This has been an issue featured much in the press, and I know there have been allegations from the press that the emissions from that sector have not been included in Canada's inventory (report submission to the UN)."


His remarks were followed by a delegate from Australia — traditionally a Canadian ally at climate negotiations — who questioned how Canada could increase its "level of ambition" when it was turning away from engaging international markets. Lebanon also jumped in, questioning the pace of a commitment to phase out subsidies for fossil fuels, including the "tarsands," and raising doubts about Canada's intention to harmonize its policies with the U.S. without matching its partner's proportion of investments in clean energy.

Honesty in Canadian emissions reporting

For five years, Canadian government represnetatives have claimed they are meeting all the obligations under the Kyoto Protocol... except the emissions target. In other words, Canada has met the reporting deadlines but achieved little else. The claim has been subject of much ridicule, here and elsewhere. [it is, incidentally, a classic and well-documented problem with international policy; governments viewing success as filling out the paperwork, not achieving the goals of the actual policy]

It turns out, we are now aren't even filling out the paperwork properly:

OTTAWA — The federal government has acknowledged that it deliberately excluded data indicating a 20 per cent increase in annual pollution from Canada’s oilsands industry in 2009 from a recent 567-page report on climate change that it was required to submit to the United Nations...

The numbers, uncovered by Postmedia News, were left out of the report, a national inventory on Canada’s greenhouse gas pollution. It revealed a six per cent drop in annual emissions for the entire economy from 2008 to 2009, but does not directly show the extent of pollution from the oilsands production, which is greater than the greenhouse gas emissions of all the cars driven on Canadian roads.

... Environment Canada provided the oilsands numbers in response to questions from Postmedia News about why it had omitted the information from its report after publishing more detailed data in previous years. A department spokesman explained that “some” of the information was still available in the latest report, which still meets Canada’s reporting obligations under the UN Framework Convention on Climate Change.
“The information is presented in this way to be consistent with UNFCCC reporting requirements, which are divided into broad, international sectors,” wrote Mark Johnson in an email.
He was not immediately able to answer questions about who made the decision in government to exclude the numbers from the oilsands or provide a detailed explanation about changes in emissions.

To be fair, maybe this is a common problem this past year, and the reporting by other UNFCCC signatories  was also limited or delayed.
 
Although the report was due in April, during the last election campaign, Canada was the last country to file its submission. Environment Canada even filed its submission after earthquake-stricken Japan, and was unable to explain in detail why its report was late.

Climate communication: Shaking things up

I've been advocating that scientists need to experiment with new ways of communicating with the public. Now I don't know whether this video will work as a communications strategy, or whether I even agree with what they are saying ("we're scientists, you're not" could come across asarrogant), let alone the language they use to say it. But let's not be too academic here. Regardless of what you think of the finished product, this group deserves props for at least trying something different:

An argument for a gas tax

Last Thursday I gave a talk at the annual American Association of Geographers meeting in Seattle. The AAG attracts throngs and throngs of academic geographers from around the world. Frankly, the meeting is so big you need to be a geographer to navigate your way to a chosen talk, the subject of which may very well be a Marxist analysis of neoliberal influence on the map of the conference centre (“the orientation places the economic geography presentation rooms at the top”).

Seattle is just close enough to Vancouver that someone who is busy, or who possesses an unrealistic and slightly delusional sense of what is possible in a fixed amount of time, or, in my case, both, could convince himself to go there and back in a day. I chose to take the bus, rather than drive, because doing so is more energy efficient and would give me the chance to do some work.

The return bus fare was $48 (that’s Canadian $ for those of you scoring at home). It was, I later discovered, a bit of a deal – return fares can run up to $72 or so. That morning, the price of gas at the station near our house was $1.33 per litre (L). At that price, in order for a single-occupant vehicle trip to be cheaper than the bus fare, the car would need to average less than 7.88 L per 100 km (or 30 mpg) on the 458 km return trip from our house to the conference centre*.

You are unlikely to get that fuel efficiency with anything other than a small vehicle or hybrid car, especially given the traffic you can expect to encounter. And that’s not including the cost of parking. If you add in $20 for parking, the car would have needed to average 4.6 km/100 L, or 51 mpg, which is probably only possible, if at all, with a carefully-driven Toyota Prius, a Chevy Volt, one of the older two-door Honda Insights, or maybe Nissan Leaf if you asked the polar bear in the backseat to hold a bunch of extra batteries on his or her lap. Even at the premium, book-at-the-last-minute bus fare of $72, a car would still need to average at least 11.8 L/100 km (~20 mpg) excluding parking costs, or 8.5 L/100 km (27 mpg) including parking costs, in order to best the bus costs. In other words, at today’s price, there is a clear and immediate financial benefit to leaving the car in the driveway and taking the bus**.

At low prices, gasoline is inelastic. The price won’t significantly influence our behaviour. But as prices move well upwards of $1 per L (towards $4 per gallon), the story may change. The last time gas prices reached beyond today’s level there was an increased demand for high-efficiency vehicles and public transit.

The problem, to remove my scientist hat and channel Thomas Friedman, is that the price signal is coming from the wrong place. Right now, gas is expensive because of the price of oil. The proceeds are going to the oil industry – some of that money stays here in Canada, but much of it goes overseas – and inspiring more exploration, which could conceivably lower prices, or maybe to things like CEO bonuses. If the price of gas were high because of a tax, especially one for which the revenue was invested in things like transit, improved automotive fuel efficiency, battery technology and charging stations, wouldn’t we all be better off? I’d guess that the only thing people hate more than paying a premium at the pump is paying that premium to oil companies.

*L per 100 km? What foreign tongue is this you ask? Canada and the metric world measures fuel efficiency as the gasoline required to go a distance, whereas the US and some other nations use the distance you can cover on some fixed quantity of gas. That difference is in itself rather fascinating, and probably the subject of someone’s cultural geography thesis.

** A full accounting would include the wear and tear on your car – with that, the bus wins hands down over any car on the market. I’ve ignored that here because I’m interested in what will most likely factor into the choice of bus vs. car. My sense is that people don’t consider the daily dribbling costs of wear and tear when making decisions. We moan when the mechanic says you need a new fan belt, but don’t think about the prorated cost when going on a subsequent trip. So we’re unlikely to make a decision based on the per km wear and tear. This is just a hunch; I could be wrong.

Geopolitics at Climate Dialogue

Over at Climate Dialogue, Gerald Singh writes about the geopolitics of climate change and the strengths of weaknesses of scenario analyis:


... This raises the interesting question of what is the value of scenario studies. The future is inherently unpredictable, and there are entire books dedicated to the failures of humanity’s best and brightest when it comes to predicting the future. The problem is further compounded by the idea that our own predictions influence how we act in the future. But where would that leave us? If we rid ourselves of the tools that scenario analysis gives us (regardless of how poor they might be), what can we do?

The post goeson to talk about a climate change and Mexican immigration study that caused some debate last year. Check it out!

REDD: Seeing the forest for the trees

The newest Climate Dialogue post looks at the pros and cons of the Reducing Emissions from Deforestation and Forest Degradation in Developing Countries Programme (REDD+):

At first glance, the REDD+ framework seems to hold great promise; upon closer inspection, however, the list of barriers to REDD’s success is long. Most criticisms of REDD+ are focused on the details of the Programme’s framework and challenges for its implementation...

Faster sailing across the Central Pacific: Wind speeds and El Nino

The new paper by Young et al. about increasing wind speeds and wave heights over the past twenty years created a bit of a buzz in the climate science world, not to mention the sailing world. Finally some good news, the windsurfer in me first upon seeing the paper.

The paper itself does not speculate about whether human-caused climate change is the driver of the global trend in wind speeds. That may have been a wise choise, as it would be difficult, statistically or dynamically, to attribute the rend in the reasonably short time series (~23 years) to any single forcing factor.

The spatial pattern, however, is quite striking:














If there were no labels on this figure, I'd have guessed it was the trend in sea surface temperatures over the same time period. The steepest trend is in the Central Pacific, including the waters around the Gilbert and Phoenix Islands of Kiribati.

In a map of temperature trends over the past two to three decades, the Central Pacific should jump out because of the increasing frequency of "Central Pacific" El Nino events, also known as El Nino Modoki. The more freuqent occurences of the "CP" El Nino is a subject of much research, and has been attributed by some authors to climate warming. The CP El Nino is responsible for a number of mass coral bleaching events, including 2002-3 in the Phoenix Islands, 2004-5 in the Gilbert Islands, and 2009-10 across the whole region.

It is not surprising to find a similar -- at least visually, take this with a grain of salt, I've not done the statistics -- spatial pattern in the surface wind speeds across the Pacific. More frequent Central Pacific warm events likely means larger pressure gradients, more convergence, and higher winds across the region (my paper in  the Atoll Research Bulletin describesa CP El Nino event in relatively lay terms). More analysis will need to be done, but at first glance, the wind speed trends over the Pacific appear to be driven by temperature trends and the status of climate oscillations, which themselves may be driven in part by climate change.

Let’s Get the Lipstick off the Pig (at Climate Dialogue)

"Climate change is not being effectively addressed through the UNFCCC process, which has instead evolved into a sterile talk shop, unable to overcome the resistance of those who would block meaningful action on climate change."

Adaptation, Fairness and Finance at Climate Dialogue

Here's a teaser:

We face an extremely difficult, complex challenge in responding adequately to mitigate and adapt to climate change. One particularly thorny aspect of this challenge is how best the West can fulfil their ethical obligation to help developing countries build capacity and fund the level of response required to successfully adapt to climate change.

Food prices and the ongoing biofuel debate

People worldwide are being affected by a rise in the price of food. The causes are complex and interacting: last summer's drought in Russia, the price of oil, speculative trading in commodities, economic instability, political unrest on the Middle East, you name it. As Tamino mentions, some people sceptical of efforts to reduce greenhouse gas emissions blame the increase in food prices on those efforts, namely the cultivation of biofuels like corn ethanol. Though I think Tamino's post misses the point of this debate.

The impact of corn ethanol, or an individual drought, or any other individual factor, on the price of a global commodity is very hard to quantify. The diversion of the U.S. corn crop to ethanol production over the past decade has undoubtedly affected food prices, despite U.S. government claims to the contrary. The various factors have interacting, nonlinear effects on the price of each commodity, and the commodity prices each affect the others, so it is hard to work out, say, a coefficient for each driving variable. But that's not the problem.

The real problem with any "climate change mitigation = more corn ethanol = higher food prices" argument is the first part: the claim that producing corn ethanol is addressing climate change.

In reality, the use of ethanol from corn as a fuel might actually result in greater greenhouse gas emissions than the use of gasoline, because of the land and energy required to grow the corn, harvest the corn, and convert the corn to ethanol. As such, the primary motivation for the expansion of corn ethanol production in the US is not climate change. Ethanol production is about appeasing regional interests, maintaining of the agricultural subsidy system and reducing reliance on imported fuels, probably in that order. 

The only reason that corn ethanol gets promoted by politicians in the U.S. as a solution to climate change is that in the current political atmosphere, very few actual climate change mitigation proposals can pass, and because of some effective lobbying and the power of the Presidential primary process, expanding corn ethanol production looks like climate change mitigation to the public.

Throw out the word biofuels and people might think action is being taken to address climate change. Look at the acutal conversion efficiencies and total lifecycle greenhouse gas emissions of the current feedstocks in the U.S. and you find a different story.

There is definitely reason to be concerned about the market effects of diverting so much of the U.S. corn crop to ethanol production. The real key to the story, the one to to look for in the coming months, is the price of meat. The majority of cereals and oils, the commodities for which the price has spiked the most, are used to generate animal feed. If you look back to 2008, you’ll see that the price of meat is likely to spike next.
This dynamic demonstrates the real battle we face in the future. It’s not food vs. fuel, it is feed vs. fuel. If the world wants to keep using the most productive croplands to provide biofuel feedstocks, we had better be prepared to eat less or much more expensive meat.

Climate change hits the big time

I received this "important" notice from "Desmond Tutu" today. You know an issue is important when it is being abused for email scams!

Perhaps the scam could also be seen as a unintentional bit of social commentary, on the fact that a lot of aid funding for climate change adaptation or awareness generally goes on international consultants rather than to people in developing nations.

Julie Bishop and Australian Opposition parties need to do better research about climate policy

The Australian Prime Minister, who heads a minority coalition in Parliament, has proposed carbon pricing scheme that will begin in 2012. The opposition parties are lobbying hard against the scheme, or any scheme that puts a price on carbon. In her regular blog for the Sydney Morning Herald, Deputy Leader of the Opposition Julie Bishop uses an argument that will sound familiar to argues that will sound familiar to Canadians and Americans: in essence, why should "we" take action if China is not?

One of the principal arguments of the Julia Gillard - Bob Brown government to justify imposing a carbon tax on Australia is that the international effort on climate change will leave us behind and that even China is taking dramatic action to reduce its carbon emissions.

This is deeply misleading. What the government doesn't tell you is that even if the Chinese government met its stated targets of cutting carbon emissions "per unit of GDP", there will in fact be a massive increase in emissions from China for the foreseeable future.
 
And here is the evidence:

University of British Columbia Professor in Geography Simon Donner calculates in an article titled "China's emissions pledge depends entirely on economic growth" that the Chinese emissions "intensity" targets would still result in substantial emissions increases.He says: "If China keeps up the planned 8 per cent/year growth, emissions in 2020 will be 74-90 per cent higher than 2005 levels".

When I heard about this "citation" yesterday, I was puzzled. What article is she talking about? I'm fairly certainly I'd remember if I'd published an article about Chinese climate policy. It turns out she is referring to a brief Maribo post from two years ago in which I pointed out that the China's new emissions target is based on emissions intensity, and thus represents less of a decrease than it might sound. This brings up all sorts of interesting questions about appeals to authority, blog posts vs. published research, etc., which I'd be happy to discuss.

Now had the Deputy Leader or her staff or whomever writes the posts in her name contacted me or, say, done more than typed "china's emissions pledge" into Google (the post comes up #3, at least from here), she may have learned that many international policy experts think it is reasonable to allow nations with developing economies to set targets based on emissions intensity. I've written numerous posts arguing just that. In fact, that point was touched on in the previous paragraph in the post though only fully fleshed out in other posts:

It is, however, a reasonably fair way to bring a reluctant developing nation like China into an international emissions control framework.

The moral here is not what I wrote. The moral here is that Australians should be just horrified that by the lack of research and analysis being done by the opposition parties on the carbon tax proposal. They should not be citing a two-year old blog post written by a Canadian university professor for which the data is now out of date. I'd guess it took me about 20 minutes to do the analysis and write that post. Certainly that's not too much time to spend working on your position on a critical policy proposal.

The MVP of climate change communication

The Center for Climate Change Communication at George Mason is giving out the third Climate Change Communicator of the Year award. Voting is open until April 15th.

The award raises a question that comes up around award time in the sporting world. Is the most valuable player the one who produces the most - say, hits the most home runs - regardless of the success of their team? Or is the most valuable player the one who captained or contributed the most to a successful team?

If you believe the former, then the communicator of the year is the one who racked up the most statistics, be it blog posts, policy briefings, public talks, op-eds, etc. Given the rough state of public and political discourse on climate change, maybe this is like voting for the slugger on the last place team. One could argue that the most valuable communicators may not score well using the standard individual metrics, but doing more to advance the "cause".

That raises a second question: for what should we award a climate change communicator? Advancing public understanding of the science? Or influencing public or political opinion on climate change policy or solutions? These are two very different goals. The most valuable communicators might in fact be ones who best help audiences differentiate between science and judgments made based on science. In that view, the most valuable communicator will not be the strongest advocate for action.

Coverage of today's congressional hearing on climate science

The U.S. House of Representatives held a hearing about climate science this morning, as a part of the deliberations on a bill that would challenge the EPA's authority to regulate greenhouse gas emissions. These congressional hearings can seem like a circus, with a set of climate scientists countered by people with nice sounding credentials making arguments by analogy or just wholly baseless claims about climate science (case in point: just read or watch Donald Roberts' testimony).

This time the real circus may have been the coverage. After my morning class, I clicked on Science Magazine's (by then complete) live blog of the hearing with Gavin Schmidt of Real Climate in hopes of getting a feel for what had come to pass in the halls of Congress. Unfortunately, this legimate attempt at science coverage by a news organization with the aide of an expert from the field became more of a circus than most congressional hearings thanks to the commenters. I think commenter Roger Pielke Jr. posted more than Schmidt and blog host Eli Kintisch combined.

But that's the whole challenge, isn't it? Climate communication, like climate change, is a signal to noise problem.

Banning the trade of shark fins

A note unrelated to climate change: The NY Times reports that the state of California is considering a ban on the sale and possession of shark fins. Frankly, it is hard to believe that dealing in shark fins is not already illegal in North America. There is no better example of a cultural obsession with a particular "delicacy" - in this case, shark fin's soup - contributing to the demise of a wild population.

I took the picture at left just a couple weeks back in a market on the Pacific Coast of Central America. Frankly, it the photo could be from the Indian Ocean, the Caribbean or the western Pacific, I've seen the same thing on the coasts of all the tropical oceans.
You'll notice the fin-less sharks in the bin are all small: the larger sharks are dumped at sea after being "finned". The fin is worth so much more than the meat that there's no value in bringing a big heavy dead shark back ashore, even though it is obviously a potential food source. In Kiribati, people do catch sharks and sell the fins, but at least they also take the shark home to eat.

You don't have to be the least bit interested in marine conservation or the dwindling global shark population to see the practice as finning and leaving the shark behind as ridiculously wasteful. Perhaps a ban of shark fishing may be politically or logistically impossible in today's world, I don't know. I can say that if we are going to continue to catch sharks for human consumption, let's at least catch the whole shark.

Climate communication: Be aggressive or be humble?

There's continuing disagreement inside and outside the scientific community about not only what scientists should say about climate change, but how they should be saying it. The communications literature states there is not one right approach, but a range of different approaches which may be suitable depending on the audience.

The climate blogosphere got in a tizzy in January about an advance copy of the text of a talk to be presented by Kevin Trenberth at the recent American Meteorological Society. The debate centered around Trenberth's idea that certainty about climate change is so great we should invert the common "Is this event caused by climate change?" line of questioning. As it states in the abstract, "Given that global warming is unequivocal, the null hypothesis should be that all weather events are affected by global warming".

All the talks from the "Communicating Climate Change" session (One and Two) at AMS were recorded and are now available for viewing online.  Trenberth's talk and my own presentation "Making the climate a part of the human world" provide examples of two very different ways of thinking about communication of climate change (viewers be patient, the audio of my talk doesn't kick in for about 90 seconds). You might say the different methods of analysis - I take a deep historical perspective to explain the confusion of today - lead also to clear differences in what I can best describe as temperament. A simple breakdown would be that Trenberth goes on the offensive (i.e. prove me wrong) while I've been told my approach is almost defensive (i.e. let's be more humble, there's a good reason the science is hard to believe). Obviously, I'm partial to the latter, it is my research after all. I do accept that there may also be a time and a place for the former too.

Update: More discussion of these questions at Class M and Rabbet Run.

Scientists fearing judgement from their peers

I came across this funny observation about scientists in 1970 essay by mythologist Joseph Campbell:

I have noticed (haven't you) on television that when professors are asked questions they usually hum and haw and mmmm and uh until you have to ask yourself whether it is some kind of interior crisis they are experiencing, or just a loss of words for exquisite thoughts; whereas when a professional baseball or football player is asked even a pretty complicated questions, he can usually answer with ease and grace. He graduated from the womb when he was nineteen or so and the best player on the sandlot. But this other poor chap was held sitting under a canopy of professors until well into middle age, and even though he must not have acquired that degree, it came too late to be called self-confidence. He has the imprint of that professorial canopy is his IRMS ["innate releasing mechanisms"] forever and is still hoping that no one is going to be giving him bad marks for his answer.

Though these days the difference may also be media training, Campbell may have been on to something here. I'd guess that most scientists are still conditioned to fear the judgement of peers and mentors. The ones who overcome that unfortunately often come across as, and may very well be, arrogant. It is a difficult balance.

Creating a Climate for Change: Public lecture and webcast tonight

Alex Clapp from Simon Fraser University and I are presenting at a free public event tonight in downtown Vancouver sponsored by the Pacific Institute for Climate Solutions, a research consortium run by the area universities. For those not in the lower mainland, there should be a live webcast as well.

This event Creating a Climate for Change will explore scientific and social factors that influence the public's uncertainty about climate change, including socio-cultural barriers such as long-held beliefs that weather is beyond human control.

Open waters around Baffin Island this New Year

At a casual meal on the weekend, I met a couple in town from Iqualit. The capital of Canada's northern Inuit territory of Nunavut is located on Frobisher Bay in southern Baffin Island.

They told me that when they left home in mid-December, the ice on Frobisher Bay was not frozen. I almost coughed up my food; that can't be possibly be typical for December. According to the visitors, the Bay is normally frozen a month or two, or more, before Christmas, allowing people to head out on the ice for hunting, celebrating, etc.

The upper chart is the ice thickness as of December 27th, according to the Canadian Ice Service (for all you sea ice junkies who follow the NSIDC's daily updates on the Arctic, CIS has a great and I suspect underused site). The southern half of Baffin Island is on the upper right. Frobisher Bay is the more southern of the two long bays on the right, the one that is entirely blue (i.e. water). Iqualit is at the very northwestern tip of the Bay.

The bottom chart shows the ice thickness "anomaly" - the departure from normal thickness (click on it for full size) - for mid-December. Normal is based on a multi-decade average. You can see that Frobisher Bay and the surrounding waters are all in the red - they are owed some ice.  Some of the bay has frozen since these images were prepared.

The low ice thickness across the Arctic is part of a long-term trend. The current low in the SE Arctic has also been driven by the prevailing weather conditions over the past couple months. As was reported in the CBC News yesterday, a lingering high pressure system has held temperatures well above normal and limited ice formation.  That is the same weather pattern that directed the cold Arctic air masses to east coast of North America and to western Europe and caused the huge early winter snowfalls. So when you hear scientists say that record snowfalls could be related in part to climate warming and the melting Arctic, this is what they mean.

Art and the impacts of global change

This is a creative example of merging art and science.

As if it is not challenging enough to crochet a coral reef, the Institute for Figuring has developed a crochet version of a bleached coral reef (right).

The miniature reef is  complete with what appear to be a variety of species of bleached and dead corals. I believe that's a recently deceased  Acropora in the centre.

Their art installations also include a "toxic reef" made of a mixture of plastic and yarn. The jellyfish is impressive.

Wikileaks and the CRU e-mail hack

The latest Wikileaks release presents an important ethical challenge to the climate change blogs and the community as a whole.

Is it ethical to read and blog about the leaked cables, when at the same time condemning the CRU e-mail hack or "Climategate"? In both cases, the subject matter are messages that were i) stolen, ii) intended to be private, and iii) written by government employees. Not to mention that in both cases many of the message can easily be taken out of content.

Is this a false equivalence, or a potential case of hypocrisy?

If a hurricane dies at sea, does anybody count it?

This post from the Capital Weather Gang is a reminder that the lack of Atlantic hurricanes which made landfall this year does not mean it was a tepid hurricane season. The year's tracks are shown at right.

The number of named Atlantic storms (19) and number of hurricanes (12) was twice the long-term average and higher than almost all of the predictions. The difference this year is that no powerful storms struck the U.S. thanks to the response of the upper-level air flow to the El Nino / La Nina oscillation in the Pacific, a subject discussed here before.

The Atlantic hurricane discussion tends to focus almost entirely on the U.S. It is important to remember that not every country was spared. Haiti (above) is still recovering from Hurricane Tomas, in particular the outbreak of cholera caused or exacerbated by the heavy rainfall and flooding just a few weeks ago.

Summary of Caribbean Bleaching in PLoS-One by Eakin et al.

The new paper by Eakin et al. in PLoS-One (open access) summarizes the extent of the 2005 coral bleaching event in the Caribbean, an event discussed at length on Maribo. The paper includes data from dozens of coral reef sites across the Caribbean that were affected by the prolonged period of water water in the late summer and fall of 2005, the same unusual warmth which helped promote the strong Atlantic hurricane season. 

The figures at right give an idea of the scale of the event, and the scale of the data collected by Eakin et al. The top panel shows the heat stress ("degree heating weeks") experienced by reefs across the Caribbean; the lower panel summarize the percent of corals in each region that bleached (data is collected in some cases by counting number of bleaching colonies, in others by estimating the percent of total coral cover that bleached). The figure shows that bleaching tended to be the most extensive in the areas that experienced the greatest heat stress, particularly the core of the "hot spot" in the Lesser Antilles.

We've seen a near repeat of this event in the past few months; the effect of the follow-up event on living coral cover won't be known for some time. From a climate standpoint. The fact that it has happened again five years later is, in itself, remarkable. Eakin et al. report that the sea surface temperatures in the fall of 2005 were the warmest since records began in the mid-1800s. The new record appears to have only lasted five years.

The forecast for climate blogs

The previous post drawing analogies between the state of climate blogging and cable news drew a wide variety of responses, some here, some over at the Energy Collective, and some in private e-mails (if such a thing exists). There's no right answer to the question of how to respond to skepticism about well-founded scientific findings. I'm arguing that we may all benefit from taking a deep breath before raising our voices, from thinking about the big picture and not overreacting to every event.

Jon Stewart, whose call for civility inspired my post, compared himself to a climate scientist in an interview last week (thanks Keith):

This is—I‘m not saying—look, I love the voices that I hear on MSNBC. And there‘s a difference between—here‘s what‘s unfair about what I do. This is really what‘s a great—here‘s a great thing that I think is unfair.

You‘re one person with one great voice and sincere—but I‘m a climate scientist. I study weather patterns and climate. You‘re talking about the weather. Maybe these networks are not meant to be viewed in aggregate, but there is an aggregate. There is an effect.

A perfect analogy. Are the climate blogs dealing with the "weather"? Or with the climate?

[UPDATE: to hear other views, Keith Kloor is also asking readers this question]

Climate blogs, cable news and some inconvenient truths

There is a storm brewing in the climate change world. Climate policy efforts are in disarray. There’s a chance that the Congress, energized by new leadership that questions the scientific evidence for climate change, will hold hearings to investigate scientific practices. Climate scientists are preparing to defend their field.

Will the climate blogs help mediate this coming debate? Or amplify it?

I began thinking about this after seeing highlights from the Rally to Restore Sanity. If there is one forum that needs some sanity restoration, it is the climate blogs (science and political ones). Blogs highlight the extremes of the other side. Bloggers call each other names. Bloggers get grandiose and self-righteous.

Yes, absolutely, you can blame the medium. It is impersonal. It is easy to be extreme when the opponent is a collection of pixels and text rather than a living, breathing person. Plus, blogging only works if you have readers. And more controversy equals more page views.

But add it all up, and what do you get?

Cable news. Steve McIntrye as Bill O'Reilly? Joe Romm as Keith Olbermann? Anthony Watts as Glenn Beck? (plus a lot of folks hoping to be Jon Stewart?)

Just as political pundits focus on political maneuvering rather than actual policy debates, many bloggers focus on bashing each other rather than discussing the issues. We do so because it appears that shouting is the best way to get heard. So just as cable news channels have trended towards the extremes and trumped-up scandals to capture the dwindling audience and dwindling advertising dollars, many bloggers end up focusing on the controversies rather than the consensus in part just to stay afloat in a crowded online sea.

If you write nice, reasoned posts, you are less likely to get a gang of dedicated readers. If you insult the skeptics or question the scientists, the readers will come. Michael Tobis has been caught up recently; he wrote a very reasoned critique of misguided uncertainty discussion by another blogger – but it was the vitriol at the end that drew all the attention. The personalities become the subject. The medium becomes the... ok, a Canadian can never get far into a media conversation without quoting Marshall McLuhan. No particular person is to blame for the dynamic and no one is entirely immune. I’ve fallen in myself on a number of occasions.

The question we have to ask is this:

What do we hope to accomplish by blogging? Do we want to play “inside baseball”, or do we want more people to pay attention to the game? I may be wrong, but I’d guess that most of the science bloggers began their blog with an aim to educate people about climate change and to foster discussion on science and policy. Sure, there's some subconscious pleas for attention and what not at work, but I'll trust that bloggers of every stripe honestly believed their blog would improve the public discussion.

Is it working? I'd argue that the escalation of tone is not expanding the conservation conversation [thanks John!] on climate change. Everyone in the room is just shouting louder at each other. There’s no better way to alienate the broader public.

Behind the name calling and vitriol lies some neglected, one might even say inconvenient, truths.

You can think climate “skeptics” (or “alarmists”) are wrong, without thinking they are evil and/or in it for the money.

You can deconstruct an argument, without abusing the source.

You can trust the scientific consensus, but not be an alarmist.

You can agree with many of Joe Romm’s arguments, but disagree with his abrasive style.

You can disagree with Roger Pielke Jr. or Judith Curry most of the time, but agree with them sometimes.

You can know that the East Anglia e-mails have zero impact on the science of climate change and did not warrant one percent of the media coverage, but still be irritated with some of the scientists involved for the tone they used in a few of the messages.

You can agree with public statements by climate scientists about climate action, but think they are the wrong people to make such statements.

You can agree with the findings of a new study, but disagree that the findings are worthy of publicity.

You can trust the scientific consensus on climate change, but not believe that action is necessary. That may not be my personal judgment on the matter but I accept that the decision on climate action is about more than science.

And, yes, you can disagree with this post (and claim I've set up a straw blogger), but still give it some thought.

Investing in technology vs. pricing carbon

This quote from a story about a recent report on the challenge of integrating "green" cars into the marketplace contains an important policy lesson:

“While considerable interest exists among governments, media and environmentalists in promoting HEVs and BEVs, consumers will ultimately decide whether these vehicles are commercially successful or not,” said John Humphrey, senior vice president of automotive operations at J.D. Power. “Based on our research of consumer attitudes toward these technologies - and barring significant changes to public policy, including tax incentives and higher fuel economy standards - we don’t anticipate a mass migration to green vehicles in the coming decade.”

In the wake of the failed U.S. Climate Bill, the proponents of increasing government investment in research and development like the Breakthrough Institute have been out in force. One example is the report "Post Partisan Power" released by the Breakthrough Institute and Steven Hayward of the American Enterprise Institute.

Of course, investing in R&D is a fine idea. Unlike others, I'd hesitate to call the proposed R&D policies, particularly those in the Post-Partisan report, a climate policy (try searching the document with the phrases "climate change" or "global warming"). The Breakthrough crowd's central thesis of R&D investment rather than emissions controls has always struck me as a bit of dodge. Spending on R&D is presented as an alternative to carbon pricing, as if the two policies could not or should not or would not act in concert, when in fact, most pricing schemes assume some of the proceed with go to R&D. By presenting R&D investment as an either/or question, the Breakthrough folks make it seems as though proponents of carbon pricing are opponents of R&D. In reality, we find that the R&D may not have the desired effect without some policy instruments to aide the technology transition.

Climate change and the Caribbean coral bleaching, again

There's an upswing of skepticism about climate change of late, thanks in part to the crazy season in the US (and I'm not talking about the baseball playoffs, although they have been pretty surprising too). While the pundits argue, the climate keeps on moving.

When I give talks about climate change and coral reefs, I almost always use the two slides on the right. The first slide is a map of "degree heating weeks" (DHW), a measure of accumulated heat stress experienced by corals, in the Caribbean in mid-October in 2005. Severe bleaching and coral morality is typically observed when the values of DHW exceed 8 deg C-week. Basically, the same long period of warm water temperatures that helps spawn the destructive 2005 Atlantic hurricane season caused unprecedented coral bleaching event in the eastern Caribbean.

In 2007, my colleagues and I published a study examining of the likelihood of the 2005 "hot spot" occurring with and without human influence on the climate system. The study contrasted model simulations of the Caribbean with historical data and then computed the statistics of extreme ocean temperature events. The second slide summarizes some of the key results of from study. In a nutshell, our best analysis concluded the 2005 Caribbean "heat wave" would likely be on the order of a once in a thousand year event, had there been no human-generated greenhouse gas or aerosol emissions since the Industrial Revolution ("natural forcing"). By the 1990s, the human forcings increased the odds to once in 10-50 years. And continued warming under "business as usual" would make such heat waves happen in three out of every four years.

Five years later, a Caribbean "heat wave" has happened again. I've been writing for months that there was a strong likelihood of extensive coral bleaching in the Caribbean this fall according to NOAA's advance forecast of sea surface temperatures (in fact, we had a good inkling of this last summer). Now we're getting reports of bleaching from observers in the Caribbean. Add this to the observations (following predictions, once again!) from Southeast Asia and the Equatorial Pacific, and we have what may be the most, or second most, extensive "global" coral bleaching event in recorded history.

For all those writing about this event, keep in mind the predictions. This is what the scientific community predicted was likely to happen. An event which we calculated would be a once in a millennium occurrence without human impact on the climate, happened again five years later.

There are caveats, for sure. There is uncertainty in the model simulations of interannual variability which can affect the specific calculations of odds (see the 2007 paper for some details). And once-in-a-thousand year events can in reality happen five years apart; we'd need to collect data for thousands and thousands of years to properly calculate the statistics. Obviously, that's not feasible, which is the very reason we have computers help us do the math on these problems.

The real climate doesn't care about the political climate.

Coral Reefs at SciFest 2010 in St. Louis

I'll be giving a talk about coral reefs and climate change on Saturday as a part of the annual SciFest in St. Louis. If you're in the neighbourhood, drop by and learn "about how climate change threatens coral reefs across the planet, and what we can all do to help them survive."

Collaborating with industry on publications and climate solutions

The article Geoengineering: The Inescapable Truth of Getting to 350 from online hybrid magazine / academic publication The Solutions Journal appeared in my inbox today.

We can argue back and forth about the societal and ecological implications of geoengineering. That's not the point of this post. What struck me as unique in this particular article is the focus on "bioenergy" solutions, namely 'The Case for Algae', out of all the many possible geoengineering proposals. It turns out the article is written by two academics along with the chief technology and science officer of Cellana. From the Cellana website:

Cellana was established in 2007 as a joint venture between Shell and HR BioPetroleum to develop technology for the sustainable and commercial production of biofuels and animal feed from algae

Let's be clear. Developing and implementing solutions to climate change will require working with industry. We live in a capitalist system; it is willful blindness to ignore the efforts of profit-seeking outfits. So there's not necessarily anything unethical about working with industry - there certainly are cases where it will be unethical, but it is not absolute guaranteed ethical violation. Having worked on the ecological impacts of biofuels, I've certainly encountered academic scientists who consult with algae companies, because the scientists concluded algae is a far better feedstock than corn.

Does the same apply to publishing peer-reviewed articles? Is this a good example of academics working with companies to find solutions, or of a journal bridging the gap between the ivory tower and the real world? Or is this article example of "the literature" being sullied by industry influence?

Senate candidate in Wisconsin questioning climate change

Of all the elected and hoping-to-be-elected politicians openly questioning the evidence for climate change, I have personally found it most depressing to learn about the Republican Senate candidate in Wisconsin.

The state's flagship university in the capitol of Madison has a terrific Department of Atmosphere and Ocean Sciences, a place I was fortunate enough to do my PhD. There are many experts about the climate system walking to halls and the many stairs of the AOS Building.

There are reasonable arguments to make against federal climate policy.  I may disagree with those arguments. That is a personal judgment - I'd like to think an informed from years of thinking and working on the issue - but a personal judgment nonetheless. It is another to use flip analogies to argue against overwhelming scientific evidence. Especially when there are qualified people just around the corner that can help. That's 1225 West Dayton St.; at 15 stories with a big orb on the roof, quite easy to spot. I'd guess about a nice 20 minute stroll from the Capitol Square, not counting a stop at the Buraka food cart on Library Mall.
