GISS Presents Some Revisions

NASA GISS has revised their surface temperature data and 1998 has been determined to be only tied for the fourth warmest year. For January-December their top years (relative to the 1951-1980 average) are now:

2005               +0.62°C
2007, 2009      +0.57°C
1998, 2002      +0.56°C
2003               +0.55°C
2006               +0.54°C

The NASA page doesn't give the uncertainty in these numbers -- they should -- so it's hard to see any real difference in positions 2-7.

Regardless -- it's been very, very warm lately.

Here's a paper that explains their recent revisions.
