Shouldn't the show jumping horses get to stand on the medal podium along with the riders?

In honour of the Olympics

A blast from Maribo's past:

BEIJING (Unassociated Press) - The climate’s second doping sample contained elevated levels of carbon dioxide and other greenhouse gases, scientists at an Olympic doping lab confirmed on Friday.

Pierre Martin, who chairs the Olympic testing facility, said they discovered the carbon dioxide in the climate’s B sample had to have come from an outside source. The doping tests were ordered after the climate produced one of the warmest years in recorded history.

Accidents in the Arctic

This summer has seen a record number of boats - cruise ships, commercial vessels, military ships, and boats full of scientists - in the Arctic. Aware that the downward trend in ice cover is prompting an increase in boat traffic, the Canadian military decided to rehearse for any possible accidents:

Beginning tomorrow , the army, navy and air force will begin Operation Nanook 08, the latest in a series of manoeuvres designed to boost Canada's Arctic sovereignty and increase the military's ability to respond to emergencies.

Operation Nanook will simulate an outbreak of disease on a cruise ship, a hostage-taking on a cruise ship, a fuel spill and a fire on a Russian cargo ship.

Are the exercises necessary? More than you might think. Apparently the opening of the Northwest Passage is already drawing yachtees tired of the Caribbean:

A total of 26 commercial cruises are planned in the Canadian Arctic this season, a historic high and an increase of four trips over last summer. As well, at least eight private vessels are thought to be sailing in and around the Northwest Passage.

Franklin would be jealous.

Over 400 dead zones around the world (Science)

The latest issue of Science features a new review of the world's marine dead zones. Scientists have now reported over 400 regions of the coastal ocean like the Gulf of Mexico dead zone where nutrient pollution fuels the depletion of oxygen from the bottom waters, threatening ecosystem function and marine species. Most of these "hypoxic" - less than 2 mL of oxygen per litre of water - and anoxic zones arose in the last few decades due to nitrogen fertilizer use and associated intensive agricultural activities, and to industrial pollution.

The map below shows the dead zone along with a measure of the human footprint on land. The dead zones have also been plotted on Google Maps.

Coral grief

"It's a moment for straight talking, in terse, uncompromising language, to as many people as possible."

The conclusion of the Guardian's Tim Radford, after attending the International Coral Reef Society meeting last month.

Geopolartics

Recent storms north of Alaska and Siberia have accelerated the ice melt in the Arctic. The summer melt in the Arctic had been lagging behind last year (right). The shift in pressure systems, coupled with thinness of the existing ice, means this year could still give 2007 and William Connolley and run for their money.

Leaving the science aside, this means there will be no shortage of news stories about the legal battle over which countries, if any, have rights to which parts of the Arctic sea floor. To the lay observer, the competing claims to Arctic sea floor will appear either ridiculous or intractable. Or both.

More on the fierce urgency of now for coral reefs

Jim Hendee has set up the blog Educating the Masses to help organize efforts to "educate the public on the plight of coral reef ecosystems."

The future of marine fisheries

Among the many terrific talks at the International Coral Reef Symposium meeting last month was a plenary by the Daniel Pauly, head of the Sea Around Us Project of the UBC Fisheries Centre on the state of the world’s coral reef fisheries.

Aside from being one of the world’s top fisheries biologists, Pauley is among the best science communicators out there. He originated the term “shifting baselines”, a illustration of the way (fisheries) scientists often underestimate the "baseline" size of wild populations, and now also the name of a nice blog run by Jennifer Jacquet, one of Pauley’s students here in the land of salmon, and others.

The final message of his talk is worth repeating, and will be surprising to many: Small scale fisheries might be the only realistic future for marine fisheries.

The future of carbon offsets

The carbon offset game is fraught with problems. A myriad of companies now promise to offset your personal emissions through activities like protecting forests, planting trees and investing in renewable energies. Even for the most responsible and earnest of companies, the emissions reductions are difficult to quantify or verify. And many of the offset schemes fail to prevent “downstream” emissions that counteract the offsetting activity. For example, if a well-intentioned company protects the right area of the right forest from logging to “prevent” the designated amount of carbon dioxide from being released to the atmosphere, but there is no equivalent change in pulp and paper use, a forest has to be logged elsewhere to meet demand.

Here's a possible solution: Rather than pay to have a company attempt to physically offset the emissions, Carbon Retirement lets you purchase and “retire” carbon credits from the European emissions trading network. By removing those carbon credits from the market, your purchase permanently lowers the total emissions cap in the trading system. This guarantees that companies subject to the trading system will reduce emissions by the designated amount (presuming emissions are properly measured and reported within the trading system). As more trading schemes emerge – Canada, the United States and Australia are all considered trading schemes – the "retirement" method could to revolutionize, and legitimize, the consumer offset game.

[Note: I have no connection to the company. I like the concept. If other similar companies may exist, you are welcome to add links in the comments.]
