Climate change skeptic turns on deniers: some details

Eugene Robinson wraps up the Berkeley Earth Surface Temperature project results in an op-ed for the Washington Post: 

[Richard] Muller found that skeptics are wrong when they claim that a “heat island” effect from urbanization is skewing average temperature readings; monitoring instruments in rural areas show rapid warming, too. He found that skeptics are wrong to base their arguments on the fact that records from some sites seem to indicate a cooling trend, since records from at least twice as many sites clearly indicate warming. And he found that skeptics are wrong to accuse climate scientists of cherry-picking the data, since the readings that are often omitted — because they are judged unreliable — show the same warming trend.

Kevin Drum digs a little deeper, and mentions (as no newspaper story has) the BEST figure for global warming by century, and for the last ten years: 

"The earth is indeed getting warmer. Global average land temperatures have risen 0.91 degrees Celsius over the past 50 years. This is "on the high end of the existing range of reconstructions."

"The rate of increase on land is accelerating. Warming for the entire 20th century clocks in at 0.73 degrees C per century. But over the most recent 40 years, the globe has warmed>at a rate of 2.76 degrees C per century."

Warming has not abated since 1998. "The rise in average temperature over the period 1998-2010 is 2.84 degrees C per century."

Warming is accelerating, in other words, contrary to the blind optimism of the deniers.

Maybe what we're seeing here is a rift opening between climate change skeptics (who still can be persuaded with data) and deniers such as Anthony Watts (whose minds are forever closed).
