Anthony Watt has a pointer to a nice presentation in four parts on YouTube by Bob Carter made at a public forum in Australia. He walks through some of the skeptics' issues with catastrophic man-made global warming theory.
What caught my attention, though, were the pictures Mr. Carter shows in his presentation about about 1:30 into part 4. Because I took the pictures he shows, down at the University of Arizona, as part of Mr. Watts project to document temperature measurement stations. Kind of cool to see someone I don't know in a country I have (sadly) never visited using a small bit of my work. Part 4 is below, but you can find links to all four parts here.
