Quote of the Day

The temperature has risen about 10 degrees since this morning. If you extrapolate that, we will all be burned to a crisp before the end of the month.

2007 Was Earth's Second Warmest Year in a Century
Climatologists at the NASA Goddard Institute for Space Studies (GISS) at Columbia University have found that 2007 tied with 1998 for Earth's second warmest year in a century...

A minor data processing error found in the GISS temperature analysis in early 2007 does not affect the present analysis. The data processing flaw was the result of a failure to apply NOAA adjustments to U. S. Historical Climatology Network stations in 2000-2006, as the records for those years were taken from a different database (Global Historical Climatology Network). This flaw affected only 1.6% of the Earth's surface (the contiguous 48 states) and only the last several years in the 21st century. The data processing flaw did not alter the ordering of the warmest years on record and the global ranks were unaffected. In the contiguous 48 states, the statistical tie among 1934, 1998 and 2005 as the warmest year(s) was unchanged. In the current analysis, in the flawed analysis, and in the published GISS analysis, 1934 is the warmest year in the contiguous states (but not globally) by an amount (magnitude on the order of 0.01°C) that is an order of magnitude smaller than the certainty.
