A climate-change amplifying mechanism
02-26-2007 · EurekAlert!CNRS, Universités Aix-Marseille 3 et 1, IRD and Collège de France a scientific research group known as CEREGEhave highlighted a feedback mechanism of ocean circulation on the climate which reinforces this heating or cooling. Published in Nature Feb, 22, 2007, this discovery should enable better prediction of the effects of climate change on oceanic circulation.

- Woods Hole Research Center debuts new image mosaic that will strengthen global forest monitoring
11-27-2007 · EurekAlert!
Much of the upcoming UN Climate Change Conference in Bali will focus on monitoring tropical deforestation and the critical role of remote sensing systems in REDD mechanism development. Using data acquired by the Japanese Advanced Land Observing Satellite, WHRC scientists have completed the first-of-its-kind image mosaic for part of the Amazon. Images acquired globally over narrow timeframes provide for "snapshots" of deforestation, giving leverage to monitoring programs that hinge on timely, accurate forest observations.

- Drought limits tropical plant distributions, scientists at the Smithsonian report
05-02-2007 · EurekAlert!
Drought tolerance is a critical determinant of tropical plant distributions, researchers working at the Smithsonian Tropical Research Institute in Panama report in the journal Nature, May 3. In a novel coupling of experimental measurements and observed plant distributions across a tropical landscape, drought tolerance predicted plant distributions at both local and regional scales. This mechanism to explain a common observation will contribute significantly to models of land use and climate change.

- Want to monitor climate change? P-p-p-pick up a penguin!
04-03-2007 · EurekAlert!
We are used to hearing about the effects of climate change in terms of unusual animal behavior, such as altering patterns of fish and bird migration. However, scientists at the University of Birmingham are trying out an alternative bio-indicator -- the king penguin -- to investigate whether they can be used to monitor the effects of climate change.
