Today's NY Times includes "Quarter-Degree Fix Fuels Climate Fight". The piece recounts the running argument between Stephen McIntyre (climateaudit.org) and NASA's James Hansen. McIntyre cites room for doubt and disagreement while Hansen reportedly claims that, "the evidence for human-driven warming remains robust."
The article includes a chart. "This month, scientists at NASA adjusted their annual estimates of average air temperature in the lower 48 states, a change that shifted the ranking of the warmest years since 1895." It appears that 1934 is actually the warmest of the warmest and 2001 is the coolest of the warmest. Oops!
