Prominent Climatologists Skeptical of AGW Alarm

Six Prominent Climatologists; John Christy, Patrick Michaels, Richard Lindzen, Roy Spencer, Fred Singer and Sherwood Idso, all skeptical of "man-made" global warming (AGW) alarm.

"I'm sure the majority (but not all) of my IPCC colleagues cringe when I say this, but I see neither the developing catastrophe nor the smoking gun proving that human activity is to blame for most of the warming we see." - John R. Christy
