National Climate Assessment, Physical Climate, Scenarios, Modeling, Mitigation, Carbon Cycle, Adaptation
USGCRP has selected a set of emissions scenarios and climate projections to focus on for the next quadrennial National Climate Assessment. These scenarios and projections will provide a consistent basis to assess the potential future impacts of climate change and related policy choices.

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 .

New NASA research shows that Earth's atmosphere contains an unexpectedly large amount of carbon tetrachloride (CC14), an ozone -depleting chemical that was banned worldwide decades ago. According to the study, global emissions of CCl4 average 39 kilotons per year—approximately 30 percent of peak emissions prior to its banning.

As part of its most comprehensive study of climate change to date, the National Research Council today issued three reports emphasizing why the U.S. should act now to reduce greenhouse gas emissions and develop a national strategy to adapt to the inevitable impacts of climate change.
