Law enforcement agencies in Brazil announced today that they would begin investigating the cause of an oil spill that occurred off the coast. Chevron's Frade Well off the coast of Brazil has been leaking for more than a week. From the start, Chevron tried to downplay the significance of the spill, suggesting it had natural causes, but Brazilian officials are now saying that Chevron did, in fact, cause an oil spill.

Mike G at The Understory lays out the story:

Brazil’s Federal Police agency has announced that it is investigating the spill, and said in a statement that those responsible could be facing up to 5 years in prison…After Chevron tried to blame it on natural seepage for a week, officials have confirmed that the oil spill off the Brazilian coast is in fact the result of Chevron’s operations at its Frade well.

Echoing last year’s Gulf of Mexico oil disaster and BP’s defensive and often misleading public communications during that disaster, Chevron has continuously downplayed and underestimated the amount of oil that has leaked out of their well (which, according to the company, was sealed today). The oil giant claims that the amount of oil leaked out of the Frade well was somewhere between 400 and 650 barrels of oil, with only about 65 barrels worth of oil remaining on the surface of the water after a week of natural dissipation and the application of chemical dispersants.

However, independent analyses performed by organizations tell a different story.

The United Nations Climate Change talks kicked off yesterday in Cancun.  For many, the mood began much more sombrely than last year.  Copenhagen attracted celebrity clout, world leader buzz, and a sense of optimism for a binding agreement.  For all Copenhagen promised, however, those who hoped for a fair and binding global deal left empty handed.  

Along with analysts, pundits and the blogosphere, the U.S., UK and EU are already downplaying the chances of a deal being reached in the next fortnight.  And as Desmogblog reported today, those fears may not be in vain with threats that the U.S. may pull out of the talks early. 

The talks during the next two weeks are going to focus largely on forests and finance, but also on questions about the legal status of a future agreement and emissions targets, which are expected to be tackled beginning next week when ministers arrive.

The sense of general pessimism around the talks has led some to question the viability of the UN Framework Convention on Climate Change (UNFCCC) to deliver, and has led others to manufacture doubt over the scientific basis for action.  A new report released by Oxfam argues that despite the disconsolate atmosphere, a year of extreme weather conditions demonstrate more than ever that a binding climate agreement under the UN auspices is imperative.  The report, More than ever: climate talks that work for those that need them most, presents the weather events that have devastated much of the planet in the last year, and the even more harrowing costs of climate inaction.  

According to the report, at least 21,000 people died due to weather-related disasters in the first nine months of this year – more than twice the number for the whole of 2009.  “This year is on course to experience more extreme-weather events than the 10-year average of 770. It is one of the hottest years ever recorded,” wrote Tim Gore, Oxfam’s EU climate change policy adviser and report’s author.

A climate conference in Brazil’s Amazon basin has drawn indigenous groups from 11 Latin American countries, Indonesia and Congo. In the largest gathering of its kind, they came to forge a plan whereby wealthier nations would compensate developing countries for saving tropical forests.

Scientists reckon tropical deforestation causes 20 percent of the world’s greenhouse-gas emissions. An international carbon-trading plan was a central topic last December at a climate conference in Bali, Indonesia.

A face off between the world’s largest greenhouse-gas spewers has taken center stage at the UN Climate Change Conference in Bali, and China appears to be winning its public-relations battle with the U.S.

China has reiterated it will not consider mandatory emissions cuts until the U.S. and other industrialized countries such as Canada embrace a less-extravagant lifestyle. The U.S. is standing pat in its opposition to mandatory limits.

Although both countries have dug in their heels, China, which many believe has already surpassed the U.S. as the world's top emitter of heat-trapping gases, is now seen as playing a constructive role on global warming after years of dodging the issue.

In that scenario, the U.S. is losing friends fast.

President Bush is trying hard to polish his image on global warming, but buried in his fancy talk about setting long-term goals for reducing emissions by mid- 2008, the U.S. president’s core message is still the same – don’t dare mess with economic growth.

Instead of binding limits on greenhouse-gas emissions, favored by the United Nations and many countries, he’s still pushing a voluntary approach on climate change and lobbying some of the world’s biggest polluters to rally behind him.

A new survey has found growing global awareness of man’s role in climate change, together with a sense of urgency around curbing greenhouse-gas emissions. The challenge now is to get world leaders to take the necessary action.
