Did Media Or NASA Withhold Climate History Data Changes From The Public?

A change in climate history data at NASA's Goddard Institute for Space Studies recently occurred which dramatically alters the debate over global warming. Yet, this transpired with no official announcement from GISS head James Hansen, and went unreported until Steve McIntyre of Climate Audit discovered it Wednesday.

For some background, one of the key tenets of the global warming myth being advanced by Hansen and soon-to-be-Dr. Al Gore is that nine of the ten warmest years in history have occurred since 1995.

McIntyre has been crunching the numbers used to determine such things as published by GISS, and has identified that the data have recently changed such that four of the top ten warmest years in American history occurred in the 1930s, with the warmest now in 1934 instead of the much-publicized 1998.

As McIntyre wrote Wednesday (emphasis added, h/t NBer dscott):

There has been some turmoil yesterday on the leaderboard of the U.S. (Temperature) Open and there is a new leader.


Four of the top 10 are now from the 1930s: 1934, 1931, 1938 and 1939, while only 3 of the top 10 are from the last 10 years (1998, 2006, 1999). Several years (2000, 2002, 2003, 2004) fell well down the leaderboard, behind even 1900.

Most importantly, according to the GISS, 1998 is no longer the warmest year in American history. That honor once again belongs to 1934.

As global warming is such a key issue being debated all around this country and on Capitol Hill, wouldn't such a change by the agency responsible for calculating such things be important to disseminate? When this correction was made by Hansen's team at the GISS, shouldn't it have been reported?

In fact, it is quite disgraceful that it wasn't, as it suggests that a government agency is actually participating in a fraud against the American people by withholding information crucial to a major policy issue now facing the nation.

Think this will be Newsweek's next cover-story?

No, I don't either.

Post facto thought: If Hansen's team had made changes to the data which showed that ten of the ten warmest years in American history occurred since 1995, do you think that would have been reported?

Yeah, I do, too.

*****Update: This appears to be necessary given some very silly e-mail messages that I've received. Gore's claim concerning warmest years in history pertains to data for the entire planet. The changes at GISS are only for American data.

However, as e-mail messages from various scientists around the world have pointed out, American climate data collection is the finest on the planet. It is expected that when these changes are made to numbers across the globe, the worldwide rankings might see some changes as well.

Yet, still more to the point is the fact that American data were changed without any announcement.
