Gore’s movie trumpeted that 1998 was the warmest year on record. This is wrong. An error was found in the NASA GISS data and when corrected made 1934 hottest year on record, not 1998; 1921, became the third hottest year on record not 2006; three of the five hottest years on record occurred before 1940; Six of the top 10 hottest years occurred prior to 90 percent of the growth in human produced greenhouse gas emissions during the last century. If it was a genuine error then somebody should be fired, if it wasn’t there are more serious implications. Suspicions are raised by a pattern of ‘adjustments’ that make earlier years cooler thus making more recent years warmer. The procedures that cause this are explained in an article titled, “Rewriting History, Time and time again.”
The pattern of adjustments and failure to disclose methods is deeply disturbing and requires much more investigation. It parallels too closely what has happened at the IPCC and makes a mockery of their claim that, “Eleven of the last twelve years (1995-2006) rank among the twelve warmest years in the instrumental record of global surface temperature (since 1850).”
The 66% error factor is sufficient in itself to reject the argument that Jones’ figure represents an unusual increase. It is definitely inadequate to serve as the basis for a global climate and energy policy. But there is a more serious problem. - Canada Free Press
I don't feel like searching the archives, but sometime last year I made a post commenting on the correction.
