Those who dare assert the Earth’s temperature isn’t on a perilous rise are derided as “deniers.” For liberals, the climate debate has ended, and it is an unquestionable article of faith that mankind’s carbon-dioxide emanations have set the stage for rising oceans, devastating hurricanes and disasters on a scale never before seen. To say otherwise is unthinkable, and that has created a dilemma. It’s not actually getting warmer.
In a paper published Tuesday, no less an authority than NASA scientist James E. Hansen wrote, “The 5-year mean global temperature has been flat for a decade, which we interpret as a combination of natural variability and a slowdown in the growth rate of the net climate forcing.” Mr. Hansen is the intellectual godfather of the global-warming movement who advised Al Gore on his Oscar-winning climate-scare flick, “An Inconvenient Truth.” Mr. Hansen has just acknowledged more than the lack of warming. His words confirm nature, not mankind, played the decisive role in directing global temperatures over the past 10 years.
