'2006 Fifth-Warmest Year on Record'

On February 8, 2007, climatologists at the NASA Goddard Institute for Space Studies (GISS) announced that 2006 was the fifth-warmest year in the past century. GISS scientists estimated that the five warmest years on record were, in descending order, 2005, 1998, 2002, 2003, and 2006. Other climatology groups ordered the years somewhat differently due to different measuring techniques, especially in areas with sparse measurements, but they also considered these years to be the warmest. According to NASA GISS director James Hansen, 2007 is likely to see warmer temperatures than 2006 and could prove to be the warmest on record, thanks to an El Niño and continued emissions of greenhouse gases.
