It's important to be self-critical, to keep yourself from wandering off into the fever swamps. I must confess that I was a little worried when I saw this from Dr. Roy Spencer (major league climate scientist) - after all, I'm pretty skeptical here, pretty regularly. Fortunately, it looks like I haven't spouted any of these.
Worth a read. Spencer is a skeptic, but he's also a scientist. That's actually a good combination.
