Gowanus Canal goes Superfund 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 compel PRP's (principal responsible parties) to perform the cleanup or reimburse the government for EPA-led action. The EPA is now locked in to what may be a tough and perhaps a long dragged-out process of restoring the Gowanus, while forcing cooperation from PRP’s and catering to often sensitive local community interests.

Amazon Droughts and Greening 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 drought are not reproducible. Approximately 11%-12% of these drought stricken forests display greening, while, 28%-20% show browning or no change, and for the rest, the data are not of sufficient quality to characterize any changes. These changes are also not unique; approximately similar changes are observed in non-drought years as well.

New Report Offers Little Hope for International Climate Agreement 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 Purvis says that the United States and Europe should "accept reality" and take immediate practical steps to deal with global warming.

EPA defends plan to regulate Greenhouse gas emissions 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 faces an uncertain future in the Senate amid opposition from fossil fuel-rich states.
