China and India endorse Copenhagen Climate Accord

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 in December. The accord plans $100 billion a year in climate aid for developing nations from 2020 and seeks to limit global warming to below 2 degrees Celsius (3.6F) above pre-industrial times, but produced no timetable of emission limits to reach that goal.

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.
