I've always trused the NASA's data for global warming, and I've posted links to it before.
I'm glad NASA admitted that they made an error.
Here are the highlights from another article:

Al Gore claims nine of the 10 hottest years on record have occurred in the last decade.
The trouble is, it's no longer true.
A little less than a decade ago, the U.S. government changed the way it recorded temperatures.
To NASA's credit, when McIntyre pointed out their temperature errors they quickly made corrections.
The hottest year since 1880 becomes 1934 instead of 1998, which is now just second; 1921 is third.
Four of the 10 hottest years were in the 1930s, only three in the past decade.
The 15 hottest years since 1880 are spread over seven decades. Eight occurred before atmospheric carbon dioxide began its recent rise; seven occurred afterwards.
In other words, there is no discernible trend, no obvious warming of late.
