National Climate Assessment|
January 25, 2013 | U.S. Global Change Research Program
“Climate change is already affecting the American people. Certain types of weather events have become more frequent and/or intense, including heat waves, heavy downpours, and, in some regions, floods and droughts. Sea level is rising, oceans are becoming more acidic, and glaciers and arctic sea ice are melting. These changes are part of the pattern of global climate change, which is primarily driven by human activity.” Quoted from the Executive Summary of the Federal Advisory Committee Draft Climate Assessment Report
