Climate Deniers’ Top 3 Tactics

Climate deniers don’t just want to deny global warming and its danger. They want you to deny it too.

But man-made climate change is real, the danger is extreme, so they have to use guile to persuade you otherwise. There are three tried-and-false tactics they use often, and to great effect. Let’s take a close look at these misdirection methods, so you can arm yourself for defense against the dark arts.

Global Warming AND el Niño

Some people, especially climate deniers like David Rose, seem to have a hard time grasping the fact that more than one thing can affect global temperature at the same time. Some things, like man-made global warming, bring about a trend that keeps on giving. Others, like el Niño, cause temporary fluctuations that just don’t last.

A Sordid Tale of Climate Denial

It started with David Rose in the U.K. Daily Mail, was followed by a variant from Ross Clark in the U.K. Spectator, and now another version has appeared by James Delingpole in Breitbart News. They’re textbook examples of how fact is twisted to mislead, then travels around the world while the truth is still putting on its shoes.

Prolonging a NON-slowdown in global warming

A great deal of discussion lately has centered around the idea of a recent “slowdown” in global temperature. With 2016 destined to break the hottest-year-ever record for the third time in a row, it would seem to be over now, even if it was real. I say “if” because scientists disagree about whether or not it ever was even a real thing — and I’m one of those who thinks it was not.

A new paper in Nature Communications investigates the likelihood of a “prolonged slowdown in global warming in the early 21st century.” But like most (if not all) papers that discuss the so-called “slowdown” it does nothing to establish that such a slowdown is real, that it was anything but random fluctuation that looks like a slowdown. Those who do statistics, and do it right, learned one of its most important lessons a long, long time ago: that “looks like” is a very bad way to draw conclusions.
