I've posted many things about extreme temperatures and how, in the U.S., the records don't support the contention that things are getting hotter. You can look at the data by downloading a file (link on the right sidebar).
Another researcher's work in that arena is cited at Climate Science. Specifically, he states:
Greenhouse gas theory says warming should be largest in the middle to upper troposphere. Thus, daytime maximum temperatures should be much better for detecting and simulating this heat accumulation in the atmosphere.
This post has really piqued the ire of Dr. Schmidt at Real Climate.
Also, over at ICECAP, a meteorologist, Peter McGurk, has taken the work I did and extended the analysis. Although he calls me "Gary Hall" and this blog "Hall of Fame", I don't take offense and you might find his work of interest.
