2010 Will Be One Of Top Three Hottest Years on Record - Final Details Next Month
We've been writing variations of that headline for the bulk of 2010 and as the year winds down, all the projections that this year would be the hottest on record are proving true. While we won't know for certain until the early part of 2011, when the final temperature data for December is released, NASA, NOAA and now the World Meteorological Association all report (h/t The Guardian) that the past twelve months have been record-breaking.
The past 10 years have also been the hottest decade on record, with temperatures for January to October averaging 0.46C above the 1961-90 average, 0.03C above the 2000-09 mean and the highest value yet recorded for a 10-year period.
And all of this has occurred in a year where there was a declining El Niño effect and a very strong La Niña cooling things down--which according the UK's Met Office will hold global temperatures down enough so that 2011 will likely not set a new record, even if being in the top 10 warmest years recorded.
As previously reported 17 countries reported record highs this year, with Pakistan setting a new record high for Asia of 129°F (53.7°C)--symbolically at the abandoned ancient city of Mohenjo-Daro, which was abandoned at least in part due to changing regional environment conditions as the ancient Saraswati river dried up thousands of years ago.
What's more, 37 US states set new record nighttime temperatures.
The only nation in the world to set a new record low temperature was Guinea, with below normal temperatures experienced in Siberia, South America, parts of Australia, the southeast US, and northern Europe.
