Two billion people worldwide do their cooking on open fires, producing sooty pollution that shortens millions of lives and exacerbates global warming. If widely adopted, a new generation of inexpensive, durable cook stoves could go a long way toward alleviating this problem. With a single, concerted initiative, says Lakshman Guruswami, the world could save millions…

China and India joined almost all other major greenhouse gas emitters Tuesday in signing up to the climate accord struck in Copenhagen, boosting a deal strongly favored by the United States. More than 100 nations have now endorsed the Copenhagen Accord, a non-binding agreement reached after two weeks of tortuous wrangling at a 194-nation summit…

Last week, the Gowanus Canal, a 1.8-mile, 100-foot wide waterway in northwest Brooklyn which empties into Upper New York Bay, was added to the National Priorities List (NPL) otherwise known Superfund by the Environmental Protection Agency. The new designation means that the EPA will now move ahead to clean up this derelict canal and to…

The sensitivity of Amazon rain forests to dry season droughts is still poorly understood, with reports of enhanced tree mortality and forest fires on one hand, and excessive forest greening on the other. In a current story there is a report that previous conclusions of large scale greening of the Amazon as a result of…

It’s the big pink elephant in the room that few others wish to acknowledge, but a central theme in a new report by former climate negotiator Nigel Purvis: An international climate change treaty isn’t likely to be signed anytime soon. Purvis served as president Clinton’s chief UN climate negotiator, and in his report released today…

The Environmental Protection Agency chief fought back on Monday against Senate attempts to challenge the agency’s authority to regulate greenhouse gas emissions, saying delaying action would be bad for the economy. President Barack Obama has long said the EPA would take steps to regulate greenhouse gases if Congress failed to pass climate legislation. The bill…

The Toba super eruption occurred between 69,000 and 77,000 years ago at Lake Toba (present day Indonesia), and it is recognized as one of Earth’s largest known eruptions. The related catastrophe theory holds that this super volcanic event plunged the planet into a 6 to 10 year volcanic winter, which resulted in the world’s human…

SeeSouthernForests.org provides a new way to learn about, and protect, the forests of the southern United States. Changes over a large area are often hard to see. This can be especially true when it comes to forests where incremental forest loss often goes unnoticed until it is too late. A new website and report by…

The ‘innovation gap’ for neglected tropical diseases is rapidly growing, say Sandeep P. Kishore and colleagues, but research universities in the United States could help close the gap. Total research funding for diabetes is more than 15 times greater than that for malaria, and more than 100 times that of other diseases such as schistosomiasis.…
