It’s been less than a month since the Climategate files were first disclosed, but they’ve already had a dramatic impact on the debate over climate change.
On the one hand is the dominant so-called consensus — that human emission of greenhouse gases has been the primary cause of an unprecedented warming of Earth’s climate. On the other hand, there has been an underground opposition trying to make itself heard. What the disclosure of the files did was demonstrate that these opposition voices had been suppressed unfairly and unscientifically.
As a result, the raw data that had been withheld is becoming available to outside researchers. This new openness is already having results.
Steve McIntyre of Climate Audit has done a careful analysis of the Climategate emails that affect one particular issue — the “tricks” that were applied to the data in composing the various reports. The particular issue McIntyre is considering is called “the divergence problem.” When we measure temperatures now, of course, we use a thermometer. For historical temperatures, however, reliable thermometers weren’t available until about 1724, with Fahrenheit’s mercury thermometer. And regular records of temperature weren’t done until some years later…
