Activists to Obama: Stop leasing public land to take out oil, gas, coal

Public lands in the United States hold up to 450 billion tons of potential carbon emissions, in places like the Powder River Basin, home to massive coal deposits, or in offshore petroleum. If, over time, all of these emissions are released, it would be catastrophic for the climate. A new campaign is pressing President Obama to keep them in the ground forever.

In the 'new North,' forest fires are permanently altering the landscape

The end of summer in the US has seen unprecedented and catastrophic wildfires along the Pacific coast, with whole neighborhoods burned to the ground in California. But the fire season up in Alaska and elsewhere in the far north was also devastating — and the eight million or more acres burned there raise some ominous questions about the future of permafrost and boreal forests.

Atmospheric scientist and tropical storm expert Kerry Emanuel has taken a deeper look at the possible influence of climate change on supertyphoon Haiyan, and has found that global warming may have had a good deal more to do with the storm's intensity than he originally thought.

Improving the 'cold chain' could help reduce global hunger and lessen the effects of climate change

A third of the world’s food spoils in transit and never reaches the table — food that could feed more than the 870 million people on Earth who don't get enough to eat. Improved refrigeration and transportation of perishable foods through a better integrated “cold chain” could combat world hunger and mitigate climate change without the need to grow more food to feed an increasing population.
