Climate

Members of the United Nations Security Council in New York met with Joachim Schellnhuber, director of the Potsdam Institute for Climate Impact Research, who presented a number of scenarios to show the connection between climate change and global security challenges.

Climate change is a “reality that cannot be washed away,” according to notes prepared for diplomats at today’s session. “There is growing concern that with faster than anticipated acceleration, climate change may spawn consequences which are harsher than expected.”

Topics ranged from Hurricane Sandy, to fossil-fuel deposits, to glacial melting and how the seeds of conflict, unrest, and revolution are being sewn.

Abstract

Modeling studies suggest that Antarctic ozone depletion and, to a lesser degree, greenhouse gas (GHG) increase have caused the observed poleward shift in the westerly jet during the austral summer. Similar studies have not been performed previously with observational data because of difficulties in separating the two contributions. By applying a cluster analysis to daily ERA-Interim data, we found two 7- to 11-day wind clusters, one resembling the models' responses to GHG forcing and the other resembling ozone depletion. The trends in the clusters' frequency of occurrence indicate that the ozone contributed about 50% more than GHG toward the jet shift, supporting the modeling results. Moreover, tropical convection apparently plays an important role for the GHG-driven trend.

The National Academy of Sciences (NAS) and National Research Council (NRC) have released a report commissioned by the CIA and various other American intelligence agencies on the security threats posed by climate change. The report’s goal is to inform intelligence agencies as to how to best carry out monitoring to anticipate climate-related disasters, help prevent them from occurring, and, when they do, respond to emergencies. The report investigates how climate change could potentially induce social and political stresses that will affect U.S. security over the next decade.
