NOAA releases comprehensive 2011 State of the Climate report

On Tuesday, July 10, 2012, NOAA released the 2011 State of the Climate report. This report is a peer reviewed paper that was compiled by 378 scientists from 48 countries around the world. This report looks at the extreme weather events that occurred in 2011. It also analyzes global climate indicators and monitoring stations and instruments used on land, sea, ice, and sky. The report says that 2011 was the coolest year on record since 2008, but it remained above the 30-year average (1981-2010). La Nina – the cool phase of the El Niño-Southern Oscillation – was the major cooling factor, globally, in 2011. At the same time, the influence of human-caused global warming on the climate system continues to grow. The report identified “human fingerprints” in more than two dozen climate indicators examined by this international research team — from air temperatures to ocean acidity. More specifics of the report below.
According to NOAA, La Niña played a major role in the crazy weather events that occurred in 2011, such as the violent tornado outbreaks in the United States, severe droughts in southern United States, northern Mexico, and East Africa, and one of the worst summer heat waves in central and southern Europe since 2003.
