2010 ties for “warmest year on record”

(Greenland 2009)

NASA’s Goddard Institute for Space Studies (GISS) has released figures confirming that 2010 tied with 2005 for the warmest global surface temperatures ever recorded. According to the analysis, the next warmest years are 1998, 2002, 2003, 2006 and 2007.The GISS records go back to 1880.
“If the warming trend continues as is expected, if greenhouse gases continue to increase, the 2010 record will not stand for long”, says the Institute’s director James Hansen.
NASA says their temperature record is a close match with those of others, independently produced, including the UK’s
Met Office Hadley Centre
and the National Oceanic and Atmospheric Administration’s National Climatic Data Center.
Hansen says the records show a rise in temperature over the last ten years in spite of year-to-year fluctuations associated with the El Nino – La Nina cycle of tropical ocean remperature. There is also a possibility that the cold spell which had us diving for the snow shovels here in northern Europe could have been influenced by the decline of Arctic sea ice and linked to warming temperatures at more northern latitudes. The sea ice helps insulate the atmosphere from the ocean’s heat.
The GISS experts say winter weather patterns are “notoriusly chaotic”. Well, climate is certainly a complex business. But whatever way you look at it, it looks like we all have our work cut out for us to have any chance of halting the worrying upward trend in temperature.
