Warmest Year for United States

Interesting article. A quick background:
  • Using NASA surface temperature numbers, a team at NASA concluded that 1998 was the warmest year on record for the lower 48 United States.
  • However, Steve McIntyre of climateaudit.org noticed some rather odd "discontinuities" in the graphic data, all around January 2000.
  • The team at NASA apparently refused to release their algorithm to McIntyre, so he reverse engineered the algorithm and discovered the problem. He notified the team at NASA of the error.
Now this:
NASA has now silently released corrected figures, and the changes are truly astounding. The warmest year on record is now 1934. 1998 (long trumpeted by the media as record-breaking) moves to second place. 1921 takes third. In fact, 5 of the 10 warmest years on record now all occur before World War II.
I find the phrase "silently released" interesting. This is very common. Findings that support the proper "narrative" are loudly trumpeted; findings or corrections that run counter are quietly handled. A true scientist would be disinterested in outcome. I suspect these folks at NASA were fairly invested in the "global warming" narrative and this set of corrections are rather embarrassing.
