Blogger finds Y2K bug in NASA Climate Data

Posted August 11, 2007 11:02 AM

From digg:

Years of bad data corrected; 1998 no longer the warmest year on record My earlier column this week detailed the work of a volunteer team to assess problems with US temperature data used for climate modeling. One of these people is Steve McIntyre, who operates the site climateaudit.org. While inspecting historical temperature graphs, he noticed a strange discontinuity, or "jump" in many locations, all occurring around the time of January, 2000. These graphs were created by NASA's Reto Ruedy and James Hansen (who shot to fame when he accused the administration of trying to censor his views on climate change). Hansen refused to provide McKintyre with the algorithm used to generate graph data, so McKintyre reverse-engineered it. The result appeared to be a Y2K bug in the handling of the raw data.

Steve McIntyre should be commended for catching the error.

Here's the other side to that story.
