Scott Armstrong is a classic denier -- talk big, make sweeping claims, and tiptoe away when you lose on the facts.
Armstrong is still vomiting up nonsense on his website . . . the last post is dated 5/5/2010 -- but he seems to have lost all interest in the "Global Warming Challenge" that gives the site its name. And no wonder; since March, when he last updated, he's lost every month:
Gore (fictional): 0.348C
Actual (UAH): 0.50C
Gore (fictional): 0.351C
Actual (UAH): 0.54C
Gore (fictional): 0.354C
Actual (UAH): 0.44C
Armstrong has lost every month of 2010 and nine of the last ten months. Time for the "scientific forecaster" to look for honest work.
