Source: The Earth Institute at Columbia University

The National Intelligence Council (NIC) has completed a new classified assessment that explores how climate change could threaten U.S. security in the next 20 years by causing political instability, mass movements of refugees, terrorism, or conflicts over water and other resources. Among the major outside contributors of data was the Center for International Earth Science Information Network (CIESIN), a member of Columbia University’s Earth Institute. While the NIC assessment itself is confidential, the CIESIN data is public, and is posted here (PDF; 4.5 MB).
