The correction was for the U.S. The plot shown is for global temperatures and is accurate (the U.S. correction barely nudged the global temperatures).

Because the U.S. is a region and only 2% of the global surface. I actually authored a thread on this, which features some good illustrative graphics:

A little perspective on the U.S. and global temperature records

Something went wrong with the source links to the original images in the article. I recommend reading my original article. If you don't want to read everything in the comments, the post I recommend you examine is #69.

The plots of U.S. and global temperatures are here:

Bottom line: climate rarely behaves the way that you intuitively think it should (or want it to).
