2010 hits global temperature high
Standard denier response: But, but, but—SNOWSTORMS!!!11!!!1!
Although December was exceptionally cold in some places - the coldest for 100 years across the UK - other regions, such as Greenland and eastern Canada, saw unseasonably warm weather.
Standard denier response: All-natural!!!1!1!
The WMO analysis combines data from three leading research agencies, and is regarded as the most authoritative…”The 2010 data confirm the Earth’s significant long-term warming trend,” said WMO secretary-general Michel Jarraud. “The 10 warmest years on record have all occurred since 1998.”
Other indications of 2010 warmth flagged up by the WMO include the lowest extent of sea-ice cover in the Arctic since the satellite record began.
The possibility that 2010 would emerge as the warmest year on record was raised by scientists after the year began with a period of El Nino conditions - unusually warm waters in the eastern Pacific Ocean, which transfer heat from the ocean to the atmosphere.
However, a switch to the opposing La Nina conditions halfway through the year cast doubt on whether the record would be broken.
Standard denier response: SEE?!? El Nino and La Nina! All-natural! Therefore so is climate change! Nothing to do with man!
The variation between El Nino and La Nina can alter the global temperature by half a degree or so. But the variations it produces sit on top of a slow, steady warming trend dating back half a century, ascribed to the buildup of greenhouse gases in the atmosphere from industry, agriculture, deforestation and other human activities.
Fucking climate trends, how do they work? :/
