Study: Temperature Flux Of Global Warming Increased Plant Frost Damage

Widespread damage to plants from a sudden freeze that occurred across the Eastern United States from 5 April to 9 April 2007 was made worse because it had been preceded by two weeks of unusual warmth, according to an analysis published in BioScience. The a ...

Study: Arctic Tundra Could Become More Susceptible To Fire And Release Even More CO2

Research from ancient sediment cores indicates that a warming climate could make the world’s arctic tundra far more susceptible to fires than previously thought. The findings are important given the potential for tundra fires to release organic carbon – wh ...
