Post image for Heat Waves, Droughts, Floods — We Didn’t Listen!

The hilarious South Park episode “Two Days Before the Day After Tomorrow” opens with Eric Cartman and Stan Marsh playing in a motor boat that Cartman falsely claims belongs to his uncle. Cartman persuades Stan to drive the boat. Not knowing how, Stan crashes the boat into the world’s largest beaver dam, flooding the town of Beaverton.

Rather than get help, Cartman and Stan decide to tell no one and pretend they were playing at Eric’s house all afternoon. The flood leads to wild speculation not only in South Park but also in the national media and the scientific community. Stan’s father Randy is a geologist. He and his colleagues determine that global warming caused the Beaverton flood. Worse, they calculate that global warming will strike worldwide “two days before the day after tomorrow.” Randy exclaims: “Oh my God — that’s today!” There is panic in the streets.

Echoing the sermon at the end of the 2004 Sci-Fi disaster film, The Day After Tomorrow, Randy laments: “Stan, I’m afraid us adults just let you children down. We didn’t take care of our earth, and now you’ve inherited our problems. We didn’t listen!” To watch Randy’s mea culpa on YouTube, click here.

We’ve been hearing a lot from Randy’s real-world counterparts of late, which is why in recent posts, I presented evidence that climate change was not the principal factor behind the 2003 European heat wave, the 2010 Russian heat wave, the 2011 Texas drought, or the ongong Midwest drought.

What about floods? Google “global warming” and “floods,” and you’ll get 7.2 million results. Given all that ‘evidence,’ you may surprised that a new scientific study finds no correlation between rising global mean carbon dioxide concentrations (GMCO2) and flooding in the U.S.

Post image for When Will Scientists Detect a Warming Signal in Hurricane Damages?

How long will scientists have to measure annual economic damages from hurricanes before they can confidently say that global warming is making storms stronger? In An Inconvenient Truth, Al Gore claimed the evidence is already clear in the damage trends of the last several decades. But a new study finds that any warming-related increase in hurricane damages won’t be detectable for a century a more. [click to continue…]

Al Gore’s film An Inconvenient Truth bombarded audiences with image after image of hurricanes, tornadoes, floods, forest fires, and drought, creating the impression of a world in climate chaos. Gore blamed the alleged upsurge in extreme weather on global warming, that is, mankind’s sins of emission. One of Gore’s mighty pieces of evidence was a dramatic increase in insurance payments for weather-related damages. As he writes in his best-selling book of the same title:

Over the last three decades, insurance companies have seen a 15-fold increase in the amount of money paid to victims of extreme weather. Hurricanes, floods, drought, tornadoes, wildfires and other natural disasters have caused these losses [An Inconvenient Truth, p. 101].

Gore presented a chart similar to this one:

Seeing is believing, right? The problem, of course, is not merely that correlation (warmer weather/bigger losses) does not prove causation. More importantly, the economic data depicted in the chart have not been adjusted (“normalized”) to offset increases in population, wealth, and the consumer price index.
