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.
Attention: Sir/Madam,
This is to inform you that the NELSON MANDELA FOUNDATION and WILLIAM J. CLINTON FOUNDATION in Collaboration with the United Nations Framework Convention on Climate Change has held an Internet Raffle Draw, and your Email Address was among the 2010 Email Addresses that was

Climate change hits the big time

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.

Climate change and the oceans; UCAR Magazine
The UCAR Magazine has a good short review of recent research into the ocean's response to climate change. Bob Henson manages to summarize some of the new thinking about coral bleaching, plankton productivity, ocean acidification, and ocean "deoxygenation" all in one article. It's worth a read.
Climate Dialogue: Counting carbon
A new post about carbon accounting schemes is up on Climate Dialogue. Check it out!
The previous post looked at the logic behind temperature targets.

Phew, must be that global warming

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
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
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.

2022 World Cup awarded to Qatar: Energy and carbon, phff?
Apparently, the carbon footprint is not one of the FIFA's criteria for selecting a World Cup host.
The desert nation of Qatar, where temperatures in the 50s Celsius are not unusual during the day, will be building and upgrading twelve, large air-conditioned soccer stadiums for the 2022 Cup.
I can't wait 'til the 2026 World Cup at McMurdo Station in Antarctica.

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
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
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
“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
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.
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.

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
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.

Obama and Chu on piecemeal climate policy
This is from US President Obama's interview in Rolling Stone:
When I ask him [Stephen Chu] how we are going to solve this problem internationally, what he'll tell you is that we can get about a third of this done through efficiencies and existing technologies, we can get an additional chunk through some sort of pricing in carbon, but ultimately we're going to need some technological breakthroughs
It is an interesting and rather pragmatic characterization of the solution. The pricing could, of course, drive efficiencies, use of efficient technologies and the development of new breakthrough technologies. But we're seeing how a comprehensive pricing scheme is a practical and political nightmare. Implementing a national or international pricing scheme that touches on a limited set of carbon-generating activities, let one alone taxes carbon across the board, has been hard enough (in the case of Waxman-Markey, you end up with a complicated bill that alienates even the supporters of action).
Maybe people are finally coming to the realization that a piecemeal solution might actually work the best. If we can use adopt "wedges" thinking, rather than one grand solution, to reducing emissions, why not do the same for the policy that encourages the emissions reductions?
In Obama's words:
We may end up having to do it in chunks, as opposed to some sort of comprehensive omnibus legislation. But we're going to stay on this because it is good for our economy, it's good for our national security, and, ultimately, it's good for our environment.

Glacier melt and water supply in North America
It is easy to forget that many North American communities, particularly in the Canadian prairies, also depend on water that originates in mountain glaciers. Case in point, the stunning figure at right.
The shows the model-calculated river discharge of the North Saskatchewan River (at Whirlpool Point), which flows across Alberta and Saskatchewan, with (light blue) and without (dark) blue the contribution from glaciers in the Rockies. The figure was reproduced by Natural Resources Canada from an article by Comeau et al. in Hydrological Processes.
The key change, obvious from the figure, is that without the glacial water source, there will be a huge decrease in summer water flows. The result is a more typical snowmelt-dominated hydrograph (chart of seasonal river discharge), similar to something you'd see in another part of the continent.

Response to Monkton's blustering about coral reefs
This claim appears every now and then. It is a good example of the problems with all of Monckton's arguments about climate change: i) it is based on an analogy, rather than an actual physical mechanism, ii) it ignores time scales, and iii) some of the "data" used to advance his argument is simply made up.
I've included the full responses from the three experts on the coral question (Jeffrey Kiehl, Charlie Veron and Nancy Knowlton) below. Their incredulity says enough.
Response from Dr. Jeffrey Kiehl
It is ironic that Monckton will accept that the geologic record clearly indicates that high CO2 leads to warm climates (thus CO2 is a driver for climate), but then uses the existence of life at these times to conclude that we need not worry. The point is that past warm periods developed over millions of years of time and lasted for millions of years. Thus, species could adapt to these changes. However, we also know that some species did not adapt. The concern about the future is that the rate of warming that is occurring and will continue to occur over the next century is unprecedented in the deep past. It took over 30 million years for CO2 levels to drop from 900 ppmv to their present levels, we are returning Earth back to this level in a mere 90 years. The accompanying rate of warming will also be unprecedented, certainly over the lifetime of our species. The issue is that our species and others will experience a rapid and large change that will have significant impacts on survivability. So both of Monckton’s arguments are flawed.
Response from Dr. John Veron
It is not possible for me to make any sense of Mr. Monckton’s assertions as they are not based on any scientific data or views that have ever been published. The levels quoted are higher than any spikes known to have existed. The time intervals quoted bear no relevance to the history of life.
Specifically:
Cambrian Era: Calcium carbonate (limestone) of the Cambrian, which abounds, has nothing to do with atmospheric carbon dioxide. Estimates of carbon dioxide levels at this time are not known with great certainty. There were no corals in the Cambrian, symbiotic or otherwise: they had not evolved then.
The Jurassic: There were high levels of carbon dioxide possibly reaching 2000 ppm for unknown time intervals with unknown effects on marine life. The spike immediately before the Jurassic caused the third great mass extinction. This extinction, which defines the Triassic/Jurassic boundary, was so drastic that it has been known
since the early 18th century.
Response from Dr. Nancy Knowlton
This paragraph completely ignores the fact that the seawater chemistry and the buffering capacity of seawater were very different during the times described from what they are today… The problem with CO2 emissions today is that the effects of burning fossil fuels on ocean pH first operate on the scales of decades to centuries, thus causing the acidification that has been observed. Eventually the pH of the ocean will be buffered again, but for hundreds of years ocean organisms will be affected by abnormally high acidity (low pH), and it is the damages associated with acidification over the “short” term (the next hundreds of years) that concern biologists. (see also Assertion 4)
Response from Dr. Lee Kump
One must carefully distinguish between conditions that were acquired and sustained over millions of years such as these, and abrupt events such as fossil-fuel burning that disturb these longer-term equilibria. Over long time scales the carbon cycle is balanced, and the oceans (and the life in them) can form limestone at essentially any atmospheric CO2 level. On these long time scales, rivers bring the building blocks for the calcium carbonate skeleton to the ocean; when CO2 levels are high, these compounds must accumulate to higher concentrations to overcome the increased acidity generated by the CO2, but this adjustment takes only millennia.

The second "global" coral bleaching event
The NY Times article calls the concurrence of events "only the second known global bleaching of coral reefs". Though the characterization is awkward and not terribly accurate, as the bleaching is not really "global", it does point to the right comparison. The spatial extent of coral bleaching in 2010 is likely to be second to that observed in 1998, which people have taken to calling the first "global bleaching event". It is no coincidence that these "global" events occurred during two of the warmest, if not the two warmest, years in observed history.
It is also no coincidence that both 1998 and 2010 began with strong El Nino conditions, which later flipped to La Nina conditions. In a simplistic sense, that "maximizes" the area of ocean which experiences anomalous warmth that tends trigger mass coral bleaching events. This year, the El Nino event causes anomalous warmth in the eastern and central Equatorial Pacific. The migration of the West Pacific Warm Pool back westwards, as El Nino subsided, helped cause the high temperatures and bleaching in Southeast Asia and the Western Pacific. Atmospheric teleconnections may be responsible for some of the anomalous warmth in the Caribbean, as has been suggested in past studies. And as the article indicates, the recent switch to La Nina conditions is increasing concern about bleaching in the southwest Pacific, including the Great Barrier Reef, over the southern hemisphere summer.
One area of uncertainty in the science community is to what extent can coral reefs which have experienced bleaching in the recent past, whether 1998 or more recently, can become more resilient to future temperature stress. The year 2010 may serve as a great biophysical experiment.
[UPDATE: The Atlantic and Gulf Rapid Reef Assessment is inviting divers in the Caribbean to join them in "monitoring simple, ecosystem-
level pigmentation changes in live corals and any associated changes
in live coral cover using the newly updated BLAGGRA Line Transects
protocol (www.agrra.org/BLAGRRA). Sites can be very quickly and
repeatedly surveyed by small teams of 1-2 experienced divers. A
representative assessment can be made of reefs in the area affected by
bleaching, and/or sampling can be focused on special-interest sites
(such as within and outside of MPAs)"]

Another example of the Canadian government "muzzling" scientists
From the Montreal Gazette:
The Harper government has tightened the muzzle on federal scientists, going so far as to control when and what they can say about floods at the end of the last ice age.
Natural Resources Canada scientists were told this spring they need "pre-approval" from Minister Christian Paradis's office to speak with national and international journalists. Their "media lines" also need ministerial approval, say documents obtained through access-to-information legislation.
The documents say the "new" rules went into force in March and reveal how they apply not only to contentious issues including the oilsands, but benign subjects such as floods that occurred 13,000 years ago.
I'm always surprised by Canadian or American government efforts to limit or control public statements by scientists. Forget the logic of the communication policy itself. It goes without saying that controlling public appearances by scientists is bad policy in a democratic society. But it is even worse politics. Tales of muzzling always make it into the media. It's futile to attempt to hide such a policy in a world of Twitter, WikiLeaks and Youtube. And the eventual tale of "muzzling scientists" always makes the government look bad in the end. So why bother? Political masochism if you ask me.

Really, what does the Republicans "climate zombies" accomplish?
A colleague mentioned this list (also see Joe Romm) of statements about climate change by Republican candidates for Senate. With one exception, they all doubt that human activity is responsible for climate change.
Sure I agree with all the commentators that the stance of all these candidates is depressing. The similarity of their statements suggests that it has less to do with what the individual's actually think about climate change, than the fact that climate change has become so politicized in the U.S. that Republicans need to express doubt in order to win their party's nomination. From their vantage point, denial and doubt is the only viable option.
As such, what's far more depressing to me than the statements themselves is what those statements imply about the utter failure to communicate the science of climate change and the rationale for climate change solutions in a non-partisan way. Maybe this should serve as a lesson that years of doing things like calling people who question climate change "brain-dead zombies" hasn't accomplished anything but maybe "fire up the base" (which in itself, didn't accomplish much in the past two years!)
You can be right without being arrogant. I've said it before: rather than demonize people who question climate change, it's worth thinking about their motivation and their reasoning, faulty as though it may be. Otherwise, the water will be flooding the front steps here in Vancouver, and we'll still be having the same inane arguments.

Drinking to save the climate
A group of Swedish scientists calculated the GHG emissions generated from the production of a number of different common beverages and the nutritional benefit of those beverages per unit emissions (left).
The verdict? If you want to minimize emissions, pas up on the wine and go for water, soy drinks and oat drinks (mmm?). Beer and milk are almost a dead heat in terms of emissions, though the authors caution against adding beer to your cereal in the morning [update: er, that's a joke. the paper doesn't venture into breakfast habits!].
If you want to maximize the nutritional value for each unit of climate damage (the "NDCI index"), it is milk all the way. The reason is that beer and wine offer basically zero nutritional value. Soft drinks too. Alas, it's true, there's no nutritional value to high fructose corn syrup!
With UBC being a sustainable university, milk and oat drinks will now certainly be a popular choice at all the undergrad parties and faculty functions.
The exact numbers should vary by city, region and country, based on transportation of the beverages ("drink miles"?) and production practices. I'd guess the general breakdown should be roughly similar in most locations, given that the nutrient densities are more or less constant from place to place and lower limits to the production emissions.

A year of extreme weather: Is more bleaching to come in the Caribbean?
The heat waves have not only been on land. I mentioned a few weeks ago that high ocean temperatures has led to widespread coral bleaching over the past year, including occurrences in the Central Equatorial Pacific and Indonesia.
More may be to come. This is the NOAA Coral Reef Watch bleaching outlook for the fall, based on current temperatures and an experimental long-term forecast. It calls for the possibility of "Alert Level 2" thermal stress, which in general tends to cause mass coral bleaching and some coral mortality (in reality: the response is highly variable in time and space). If the forecast is correct, observations of bleaching would probably start to happen sometime in September.

Interview with Simple Climate
A couple weeks backs, I answered a few questions about coral reefs and climate for at Andy Extance's site Simple Climate.
At the end, he asked how I would explain the global warming situation to someone who had no previous exposure at all. Of course, like any scientist, my first instinct is to launch into a discussion about the radiative transfer, the carbon cycle, etc. But explaining the science without considering the context is pointless. Here was my quick answer for Andy:
I’d start with talking about how it can be hard to “believe” that people can change the climate. For thousands of years, we’ve assumed that only powers greater than us could possible influence something as vast as the atmosphere. That’s enshrined in most cultural and religious traditions. But today, there are so many people on the planet, and we’ve consume so much energy every year, that we generate enough waste products – greenhouse gases – to alter the climate.
I’d then stress separating the science from the politics. The science tells us that human activity is changing the climate. How you want the world to respond to that information is a value judgment. As a scientist working on this subject for a number of years, I can provide you a reasonably informed opinion on the costs and benefits of different responses. But the choice is not mine alone.
After all that, if the person was still awake and interested, I’d then talk about the scientific evidence.

Climate change education: A blast from the past
"Our industrial civilization has been pouring carbon dioxide into the atmosphere at a great rate... If it remained, it would have a very marked warming effect on the earth's climate, but most of it will probably be absorbed by the oceans. Conceivably, however, it could cause significant melting of the great icecaps and raise sea levels in time."
From Planet Earth: The mystery with 100,000 clues, a brochure produced by the U.S. National Academy of Science as part of the first International Geophysical Year, 1957-1958.
The terrific, very 1950s, accompanying film "The Inconstant Air" describes the basics of weather and climate, including the greenhouse effect. What I find most fascinating is the film provides historical context to the viewer - i.e. mentioning that early human societies though that gods controlled the weather - something that is generally missing from education and outreach on climate change today. We are so buried in the politics, we forget and ignore history, and therefore fail to appreciate that the very premise (that humans are affecting the climate) is quite revolutionary.

Yes, this is the Environment Canada forecast for Vancouver
The text version includes the phrase "Local smoke", which usually has other connotations out here on the West Coast.
It is very hazy outside, but the situation is far worse across the world in Moscow.

Widespread coral bleaching over the past year
Maribo's been quiet the past few months because of field work, other research, the Canadian summer and a major case of blog exhaustion. I may be inspired to write more on the exhaustion issue later, we'll see.
In the meantime: Last year, I mentioned that several parts of the Indo-Pacific were at risk of coral bleaching in the coming year. The same El Nino event that melted the Vancouver Olympics and weakened last year's Atlantic hurricane season, did indeed cause coral bleaching across the Central Equatorial Pacific from October through the spring. We're still putting together the data for Kiribati (home of this whimsical coral).
The Pacific since sloshed back towards more neutral or La Nina conditions, the unusual warmth has been pushed to the western Pacific and Asia, leading to bleaching in Thailand, Malaysia and other parts of SE Asia. Add it all up, and 2010, which the data shows may end up being the warmest or second year in the observed temperature record, may end up also having the most extensive bleaching since 1998.
The management response in Malaysia is impressive. The Department of Marine Parks has banned diving in several popular dive sites in order to give the reefs the best chance to recover (the Telegraph):
"We expect [the corals] to recover or at least improve." Mr Abdul Jamal said The Department of Marine Parks claimed the damaged coral was solely the result of rising sea temperatures and not tourism activities.
However, Mr Abdul Jamal explained that by banning diving, the coral will be given time to regenerate naturally. The closures are likely to affect tourism revenue over the summer, but authorities argue the priority is to safeguard one of the country's main attractions – its coral reefs.
Will this ensure the coral reefs recover to the previous state? No, but it increases the odds. Short of covering the entire reef with a sheet, you can't really stop a bleaching event. But you can manage the system to encourage recovery. This is the type of management - of climate change adaptation - that many of us in the community have argued is necessary to help coral reefs survive the predicted warming over the coming decades.

"I think the sun has come closer to our island"
(why it is warmer and the copra dries faster than in the old days, according to a 97-year old Kiribati unimwane or elder)
The quote came to me second hand, via Kiribati religious leader I met while conducted a field project in the Central and Northern Gilbert Islands. It comes with the usual caveats about translation and the accuracy of anecdotal climate observations.

Record warmth continues in March
The unprecedented warmth across Canada stands out in the NOAA global temperature map for March. But Canada was not alone. According to NOAA's data, this was the warmest March and the fourth warmest January - March in recorded history.

Climate change and human rights
I had a nice long interview about different aspects of climate change with human rights expert Darren Thorne as part of a new podcast series Human Rights and Wrongs, hosted by the Mark. As always, feedback and comments are welcome.
[Update] On the podcast, we discuss the pitfalls of Canada relying on the US to determine climate policy. One of the problems is that it may be a long wait. From the Globe and Mail:
Environment Minister Jim Prentice is signalling further delays in imposing greenhouse gas emission standards on the oil sector and other industries, saying Ottawa does not want to lose jobs and investment by driving activity out of the country.
The Conservative government is waiting for the United States to decide how it will impose climate-change regulations before acting here. And the U.S. Congress could take up to two years to pass legislation that sets caps on greenhouse gas emissions, Mr. Prentice told a Senate committee Thursday.
Add the delay to the fact that the whatever US legislation is produced will be tailored to the US economy (i.e. provide loopholes for industries that are more prominent in the US than in Canada), and there's even more reason to pursue a national strategy.

The Mark: Why U.S. environmentalists should support offshore drilling

Pod science: PRI's The World Science
For all those lamenting the decline of science journalism in print and on television, its worth checking out the growing number of science podcasts.
One great example is Public Radio International's The World: Science hosted by Rhitu Chaterjee. The show has a more global focus than most other programs, including some recent interviews with young inventors in India and this week's discussion of the international politics of geoengineering. The show also features a fun segment on the music that scientists listen to while they work. The music segment features yours truly this week, but don't hold that against the show!

Tongue-tied on global warming
A few days ago, I waded into the old "global warming" vs. "climate change" debate to demonstrate a simple point about public communication.
The issue at hand is not which term is most appropriate. Of course, there is a legitimate argument to be had on that question. Michael Tobis intelligently advocates for climate change, as do most scientists. Others argue that the two terms describe different phenomena and should not be used interchangeably.
These arguments highlight the very disconnect between scientists and the public that I was getting at in the initial post. I'll obnoxiously quote myself:
Rights and wrongs of the different labels aside, the fact is that there is a disconnect here. We use a term that means less to people. And it puts scientists and others communicating the real scientific consensus at a disadvantage.
Too often, we are oblivious to the way the public perceives science. And if we do see the disconnect between scientific and public language (or style), we tend to stubbornly insist that our language (or style) is the only correct option. This only exacerbates the problem. High-minded debates about semantics like the phrase-ology certainly won't diminish the common view that academics and scientists are disconnected from reality.
Should we suspend those debates? Of course not. But let's save our energy for the more critical issues. We also shouldn't allow semantic debate to get in the way of public communication, as the Google search history I showed suggests may be the case. Like many scientists, I not wild about the terms global warming or ocean acidification or ozone hole; but if the price of increasing public understanding of the science is occassionally having to say one term instead of another, well, that's a pretty good deal.

Coal ship runs aground on Great Barrier Reef
Ironic, yes. Why bother with that whole slow process of burning the coal and oil, then having to wait for the emitted CO2 to change the climate and alter the ocean chemistry, thus threatening corals that are the cornerstone of the Great Barrier Reef, when you can just ram a ship right into the reef itself?
From the Onion New York Times:
BRISBANE, Australia (AP) -- A coal-carrying ship that strayed outside a shipping lane and ran aground in protected waters was leaking oil on Australia's Great Barrier Reef and was in danger of breaking apart, officials said Sunday.

Global warming trumps climate change?
So much of the online climate "debate" is about effective communication, not science. Earlier this week, I met with a public opinion expert who critiqued the way many scientists and environmental groups speak about, er, climate change, no global warming, maybe the climate crisis, global heating, countdown to a meltdown, springtime for CO2, waterworld, the greatest threat facing humanity, well, you know what I mean.
The expert raised example after example of scientists, NGOs, government, etc. shooting themselves in the foot while talking about, um, the impact of human activity on the climate system. Take the oldest argument of them all: global warming or climate change?
At right is the Google trends graph of average worldwide searches for global warming (in blue) and climate change (in red). The top graph is standard Google searches, the bottom graph is news references.
The graph shows that "global warming" is far more common a search term. The average person is more likely to use and recognize the label "global warming", as evidenced by the search volume. But "climate change" appears more often in the news. Why? In no small part because all the writers, and especially all the people quoted in the articles, say "climate change".
Now, we can argue the semantics of the different terms. Generally, scientists reject the term "global warming", because it is not used in the literature and supposedly "less accurate" because the entire planet is not warming at the same rate. I've used that argument many times, and now wonder if it may be a mistake to do so (as has been pointed out to me, "global" simply implies the whole planet is warming, which is true!).
Rights and wrongs of the different labels aside, the fact is that there is a disconnect here. We use a term that means less to people. And it puts scientists and others communicating the real scientific consensus at a disadvantage. Do a Google search for "global warming" and "climate change". With "global warming", the term the public is more likely to use, a "skeptical" site comes up second [note: search is done from Canada, others may find different results].

An update to the provincial greenhouse gas targets
The government of Saskatchewan is working on a greenhouse gas policy that includes an target of a 20% reduction in emissions below 2006 levels by 2020. That translates to a 31% increase over 1990 levels (the Kyoto / UNFCCC baseline), because emissions increased 63% between 1990 and 2006 due primarily to mining and resource development. The target on the previous chart was calculated using older information.
This demonstrates that choice of base year for a federal opt-in program could be contentious, as Saskatchewan is unlikely to participate if the minimum acceptable target in the federal program is calculated using a 1990 baseline.

Climate policy on campus: UBC sets aggressive greenhouse gas targets
This is an example of how a climate policy framework can inspire the motivated.
The University of British Columbia (my institution) just adopted very aggressive greenhouse gas reduction targets including a 33% reduction (below 2007 levels) by 2015.
Why? To set an example, for one. The other reason?
Under the province of British Columbia's system, all public institutions have to be carbon-neutral by the end of this year. That's virtually impossible for most institutions so UBC and other public institutions will be paying into a provincial offsets fund.
I do trust that independent of the BC climate policy, UBC is motivated to take action of greenhouse gas emissions. The policy gave the university the necessary nudge. That's the crux of my federal "opt-in" proposal. Nudge the willing.
The opt-in climate policy for Canada: Some details
Since people are asking, here's a little bit of background on my climate policy proposal in the Mark.
I trust that to many an "optional" climate policy smells fishy, like setting voluntary targets that companies or jurisdictions will then volunteer to ignore. There are three critical distinctions.
First, this policy is designed to mobilize willing participants.
Second, the provinces in the program will each have set binding, not voluntary, targets. The participation is voluntary, but once a province opts in, it is bound to the target.
Third, a point echoed nicely by Barry Saxifrage, the provincially revenue-neutral carbon tax means that participating provinces, though bound to the federal system, would otherwise have some freedom (financially) in achieving the target.
The current government is quietly awaiting a decision from the U.S. Negotiations are ongoing in the US Senate. There is no guarantee that any of the Senate bills will a) pass given current disagreements, b) be any more acceptable to the provinces with carbon-intensive industries like Alberta than any previous federal or international proposals, or c) gel with current plans in the more active provinces. And many of the programs in the existing Senate bills would not take effect for several years. Why not set a Canadian policy, one that mobilizes the very real and current enthusiasm for action in much of the country, now? If the US does eventually pass a Bill that is in the best interests of Canada and the climate, we can adapt our program to be compatible with that of the US.

The Mark: A new climate change policy for Canada
My proposal for a compromise deal that could break the long stalemate between Alberta and the other provinces on climate change appears in the Mark.
The compromise solution is an “opt-in” federal climate change program. The program would include a range of existing and proposed policy instruments, like a carbon tax that is revenue-neutral at the provincial level, targeted tax incentives or rebates for efficiency measures, and feed-in tariffs for renewable energy.
The key is that in order to join the program, a province would need to adopt an emissions target that meets or exceeds some minimum federal target. If, for example, the minimum was the U.S. target adopted by the Harper government, nine of the ten provinces would be eligible.
The level of access to the federal dollars in the program would be pro-rated to that province’s emissions target. Failure to achieve the target would lead to reimbursement of the federal program. If Alberta, or another province like Saskatchewan, elected not to participate, there would be no direct cost or punishment. Provinces outside the system could still negotiate targeted federal investments to support emissions reductions, like support for carbon capture and storage research.
Canada has been arguing about climate policy since the mid-1990s, and there is still no federal plan. This compromise could get the willing provinces working together to reduce emissions.

The warmest, driest winter on record in Canada
According to Environment Canada, the winter of 2009/10 was the warmest and the driest since national records were kept in 1948. The country was 4.0 C warmer and 22% drier than "normal", which for those of you scoring at home, is the 1971-2000 1951-1980 mean.

Meditations on climate change "skepticism"
The radio program "Are we alone?" from the SETI Institute does a regular series on skepticism in science. This week's show looks at climate change skepticism and features a terrific interview with Steve Schneider, as well as some thoughts from Naomi Oreskes. Former Apollo astronaut Phil Chapman offers his reasons for being a "skeptic", including the rather crazy unscientific claim that the rise in atmospheric carbon dioxide may be natural. Rather than present climate scientist and skeptic as a journalistic he-said, she-said, the show lets the scientific experts on the subject explain where the less informed "skeptic" is wrong. As I've argued many times, it's worth thinking about the motivation behind skepticism and the genesis of skeptical arguments, faulty as they may be, in order to improve outreach and communication.
I'm on later in the program discussing coral bleaching and ocean acidification.
