Oregon State University Scientists have long been concerned that global warming may push Earth's climate system across a "tipping point," where rapid melting of ice and further warming may become irreversible -- a hotly debated scenario with an unclear picture of what this point of no return may look like. A newly published study by researchers at Oregon State University probed the geologic past to understand mechanisms of abrupt climate change. The study pinpoints the emergence of...

redOrbit Staff & Wire Reports - Your Universe Online New research suggests that the southern part of the Amazon Rainforest faces a higher risk of dieback (the gradual dying of plant shoots beginning at the tip) as a result of seasonal drying than reported by climate models used by the most recent Intergovernmental Panel on Climate Change (IPCC). Furthermore, University of Texas at Austin Jackson School of Geosciences professor Rong Fu and her colleagues report that severe loss of...

Siberia Could Experience Widespread Permafrost Thaw Due To Global Warming

Lee Rannals for redOrbit.com — Your Universe Online More evidence is pointing to the nightmare scenario that global warming is taking a toll on our planet. Oxford University scientists say that a global temperature rise of 2.7 degrees Fahrenheit could thaw the ground over a large area of Siberia, threatening the release of carbon from soil. If the thawing of Siberia's permafrost occurs, it could see that over 1,000 gigatons of the greenhouse gases carbon dioxide and methane are...

As they typically result from severe external perturbations, it is of vital interest how stable the most desirable state is. Surprisingly, this basic question has so far received little attention. Now scientists of the Potsdam Institute for Climate Impact Research (PIK), in a paper published in Nature Physics, propose a new concept for quantifying stability. "Up to now, science was able to say if a complex system is stable or not, but it wasn't able to properly say how stable it is," says...
