Thawing permafrost releases greenhouse gases into the atmosphere

A new synthesis published in Nature suggests that thawing Arctic permafrost will release greenhouse gases gradually, rather than in a sudden "bomb". The gradual rate of these natural emissions may give society more time to adapt to their effects, but they remain a challenge for climate mitigation.

A new report investigates the causes of extreme weather and climate events that occurred around the world in 2013, finding evidence for both human and natural influences.

What does the future of climate look like where you live? For the first time, maps and summaries of temperature and precipitation projections for the 21st century are accessible at a county-by-county level, thanks to a website developed by the U.S. Geological Survey (USGS) in collaboration with the College of Earth, Oceanic and Atmospheric Sciences at Oregon State University.

Using previously published large-scale climate model projections, a team of scientists from NASA has recently released monthly climate projections for the United States at a scale of one half mile (800 meters), or approximately the size of a neighborhood.

From March - May, the rains are expected to total only 60 to 85 percentage of the average rainfall in this region. This is a significant deterioration...
