It was the pivotal international conference of the new century. Tens of thousands showed up, including heads of state, officials at all levels of government, representatives of environmental organizations, and ordinary citizens from nearly 200 countries. Scientists had warned that, without a strong agreement to reduce carbon emissions, the consequences for civilization and the world's ecosystems would be cataclysmic. [...more]
A strange cloud envelops human civilization as its leaders fail to take the measures to protect it that they themselves endorsed just five months ago. It is oddly fitting that the latest act in humanity's climate-crisis drama will occur next week in the city where history's most famous Dane, brooding in his fog-enshrouded castle, failed to act decisively upon the very question hanging over the upcoming conference in Copenhagen, Denmark.

Georgia Tech City and Regional Planning Professor Brian Stone is publishing a paper in the December edition of Environmental Science and Technology that suggests policymakers need to address the influence of global deforestation and urbanization on climate change, in addition to greenhouse gas emissions.

Over the next 18 months Patrick O. Brown, a Stanford University biochemist, will take a break from his normal scientific work (finding out how a small number of genes are translated into a much larger number of proteins) in order to change the way the world farms and eats. He wants to put an end to animal farming, or at least put a significant dent in our global hunger for cows, pigs and chickens. [...more]
Alarmed by a substantial oversight in the global climate talks leading up to the United Nations Climate Change Conference in Copenhagen next month, more than 60 of the world's most prominent agricultural scientists and leaders underscored how the almost total absence of agriculture in the agreement could lead to widespread famine and food shortages in the years ahead.

When a meat-based entrée is being served, and people are offered a vegetarian alternative, about 5 to 10 percent will request it. But what if the choices were reversed? Organizers of the 2009 Behavior, Energy and Climate Change Conference, which began Monday in Washington, tried an experiment: They made a vegetarian lunch the default option, and gave meat eaters the choice of opting out. Some 80 percent went for the veggies, not because there were lots of vegetarians in the crowd of about 700 people but because the choice was framed differently. [...more]
I gave a talk in South Texas recently on the environmental virtues of a vegetarian diet. As you might imagine, the reception was chilly. In fact, the only applause came during the Q&A period when a member of the audience said that my lecture made him want to go out and eat even more meat. "Plus," he added, "what I eat is my business -- it's personal." [...more]
There is certainly a Seattle quality to the Copenhagen mobilization: the huge range of groups that will be there; the diverse tactics that will be on display; and the developing-country governments ready to bring activist demands into the summit. But Copenhagen is not merely a Seattle do-over. It feels, instead, as though the progressive tectonic plates are shifting, creating a movement that builds on the strengths of an earlier era but also learns from its mistakes. [...more]
"To talk about global cooling at the end of the hottest decade the planet has experienced in many thousands of years is ridiculous," said Ken Caldeira, a climate scientist at the Carnegie Institution at Stanford. [...more]
In the Amazon the cattle sector is the largest driver of rainforest destruction, accounting for 60 to 70 percent of deforestation. To put it in concrete terms: every eighteen seconds on average one hectare of Amazon rainforest is being lost to cattle ranchers. As if the carbon emissions resulting from cattle deforestation were not enough, consider bovine methane emissions (or cow farts, if you want to be less delicate). While much of the debate surrounding global warming has centered upon carbon dioxide--the world’s most abundant greenhouse gas--methane, which has twenty-one times the warming potential of carbon dioxide, is seldom mentioned.
