Last year was one of the two warmest years on record, according to the 2010 State of the Climate report, which NOAA released on Tuesday.
The peer-reviewed report, issued in coordination with the American Meteorological Society, was compiled by 368 scientists from 45 countries. It provides a detailed, yearly update on global climate indicators, notable climate events and other climate information from every continent.
While several well-known cyclical weather patterns had a significant influence on weather and climate events throughout the year, the comprehensive analysis of indicators shows a continuation of the long-term trends scientists have seen during the last 50 years, consistent with global climate change.
Noted were near record air and sea temperatures, increased ocean salinity, shrinking Arctic ice and rising greenhouse gases.
