The Amazonian apocalypse is just around the corner, according to scientists gathered at the conference launching the International Year of Biodiversity. By Stephen Leahy PARIS, Feb 1 (Tierramérica).- The Amazon forest “is very close to a tipping point,” and if destruction continues, it could shrink to one third of its original size in just 65 […]
BIRMINGHAM, Ala. – The increasing acidity of the world’s oceans – and that acidity’s growing threat to marine species – are definitive proof that the atmospheric carbon dioxide that is causing climate change is also negatively affecting the marine environment, says world-renowned Antarctic marine biologist Jim McClintock, Ph.D., professor in the University of Alabama at […]

By Jeremy Hance, www.mongabay.comJanuary 24, 2010 From 2003-2006, Java lost approximately 2,500 hectares a year (10,000 hectares of forest in total) according to the Forestry Ministry. Despite the rate of loss being far lower in Java than other Indonesian islands (such as Borneo, Sumatra, and Sulawesi), Java is particularly threatened because there is so little […]
A sweeping 15-year study of pH levels in the Pacific Ocean confirmed that upper reaches of the sea are becoming increasingly more acidic. By Sandi Doughton, Seattle Times science reporter The most extensive survey of pH levels in the Pacific Ocean confirms what spot measurements have suggested: From Hawaii to Alaska, the upper reaches of […]
By GAYATHRI VAIDYANATHAN of ClimateWirePublished: January 15, 2010 Tree death rates could increase globally because of rising temperatures and prolonged droughts linked to climate change, according to multiple studies. The reasons for tree mortality in a warmer, drier world have been narrowed down to three main scenarios — greater prevalence of insects and diseases in […]
Iron-poor oceans may cause populations of phytoplankton — a critical base of the marine food chain — to decline. By Jessica Marshall | Thu Jan 14, 2010 09:55 AM ET Rising acid levels in the world’s oceans appear to be robbing the tiny animals that form the bedrock of the marine food web of a […]
The treeless ecosystem of mosses, lichens, and berry plants is giving way to shrub land and boreal forest. As scientists study the transformation, they are discovering that major warming-related events, including fires and the collapse of slopes due to melting permafrost, are leading to the loss of tundra in the Arctic. By Bill Sherwonit During […]

(University of Colorado at Boulder) Contrary to conventional belief, as the climate warms and growing seasons lengthen subalpine forests are likely to soak up less carbon dioxide, according to a new University of Colorado at Boulder study. As a result, more of the greenhouse gas will be left to concentrate in the atmosphere. “Our […]
