This was a surprise to me. A previous presentation I made on the issues with the surface temperature record got turned into a video.

From the YouTube description: Anthony Watts, founder and editor at wattsupwiththat.com, explains why the oft-reported surface temperature record is inaccurate, misleading, and an insult to proper science.

Some graphics in this presentation are from Tony Heller from realclimatescience.com

Bonus video:

A few years ago I was interviewed for PBS News Hour, which caused a lot of liberal heads to explode.
