How the Climate System Works

Monday, August 1, 2011

  • In early 2010, water temperatures in the eastern tropical Pacific were warmer than average, but a summertime reversal cooled the region off over the rest of the year.

  • Between January and April 2010, temperatures in the Pacific were under the warming influence of a fading El Niño episode. Meanwhile, higher latitudes of the Northern Hemisphere were dominated by a strong negative phase of the Arctic Oscillation.

  • In 2010, global temperatures were marked by near-record warmth and strong natural variability. This is the first in a series of posts highlighting findings from the "State of the Climate in 2010" report.
