2012 was one of the 10 warmest years on record globally
06 August 2013
Worldwide, 2012 was among the 10 warmest years on record according to the 2012 State of the Climate report released online 06 August by the American Meteorological Society (AMS). The peer-reviewed report, with scientists from NOAA's National Climatic Data Center in Asheville, N.C., serving as lead editors, was compiled by 384 scientists from 52 countries. It provides a detailed update on global climate indicators, notable weather events, and other data collected by environmental monitoring stations and instruments on land, sea, ice, and sky.
"Many of the events that made 2012 such an interesting year are part of the long-term trends we see in a changing and varying climate - carbon levels are climbing, sea levels are rising, Arctic sea ice is melting, and our planet as a whole is becoming a warmer place," said Acting NOAA Administrator Kathryn D. Sullivan, Ph.D. "This annual report is well-researched, well-respected, and well-used; it is a superb example of the timely, actionable climate information that people need from NOAA to help prepare for extremes in our ever-changing environment."
Conditions in the Arctic were a major story of 2012, with the region experiencing unprecedented change and breaking several records. Sea ice shrank to its smallest "summer minimum" extent since satellite records began 34 years ago. In addition, more than 97 percent of the Greenland ice sheet showed some form of melt during the summer, four times greater than the 1981-2010 average melt extent.
