Two papers published in the journal Science today* by Microsoft Research ecologist Drew Purves together with research colleagues at Princeton University and universities in Madrid, Spain, highlight how an improved understanding of forest dynamics is needed to better predict environmental change.
Tradition Energy, a full-service energy management advisor and one of the nation's largest energy procurement firms, today announced the procurement of 100% green power for Third Sector New England (TSNE)'s NonProfit Center.
New research from the American Museum of Natural History provides the first detailed study showing that global warming forces species to move up tropical mountains as their habitats shift upward.
Air New Zealand announced today it expects to use at least one million barrels of environmentally sustainable fuel annually by 2013.
Global climate change will not only impact plants and animals but will also affect bacteria, fungi and other microbial populations that perform a myriad of functions important to life on earth. It is not entirely certain what those effects will be, but they could be significant and will probably not be good, say researchers today at a scientific meeting in Boston.
Ecosystems are constantly exchanging materials through the movement of air in the atmosphere and water in lakes and rivers. The effects of humans, however, are another major source of connections among ecosystems.

The researchers posit that the methane was released gradually at first and then in abundance from clathrates – methane ice that forms and stabilizes beneath ice sheets under specific temperatures and pressures. When the ice sheets became unstable, they collapsed, releasing pressure on the clathrates which began to degas.
An abrupt release of methane, a powerful greenhouse gas, from ice sheets that extended to Earth's low latitudes some 635 million years ago caused a dramatic shift in climate, scientists funded by the National Science Foundation (NSF) report in this week's issue of the journal Nature.
