2008 Cooling

Building on prior post, NASA data shows:

Continuing the 10 year trend of declining temperatures, 2008 was significantly colder than 2007. Global temperatures for the year were below the average over the past 30 years. 2008 ranked 14th coldest of the 30 years measured by NASA satellite instruments since they were first launched in 1979. It was the coldest year since 2000.

“The substantial and continuing La NiƱa cooled the Earth quite a bit in 2008, to the point that it was slightly below the 30-year average [1979-2008] but slightly above the 20-year average [1979-1998],” said John Christy, distinguished professor of atmospheric science and director of the Earth System Science Center at the University of Alabama in Huntsville (UAH).
