What happened to that image? Back in 1999, Dr. James Hansen of NASA penned a report on surface temperatures still located on their servers. However, the critical figure for the report, a GIF image, has mysteriously become garbled. Steve Goddard has the back-story at his blog Real Science: “Data Corruption at GISS“
In 1999, Hansen wrote a report which was largely inconsistent with his current claims. Twelve years ago he understood that the US climate was hotter and more extreme in the 1930s. He also knew that 1934 was the hottest year in the US.
Steve McIntyre of ClimateAudit discussed part of the issue with GISS data adjustments back in 2007 with a post here at WUWT, see:
Regardless, help NASA fix this “clerical” error, as the original image exists all over the internet:
UPDATE: Steve Goddard reports that it has been repaired:
It now has the original file date, too. I’d sure like to know who modified the file on Tuesday, January 18, 2011 at 6:33:14 PM.
