IPCC and Sceptics Agree: Climate Change Is Not Causing Extreme Weather

Climate theory used to hold that there was a link between the amount of extreme weather and the equator-pole temperature gradient, meaning that warming poles should mean less of it, not more. But nowadays almost anything unusual can be labelled extreme weather by alarmists, creating headlines but no understanding of the climate.

A new Global Warming Policy Foundation report from retired physicist Ralph Alexander, Ph.D. (Oxford University) supports the Intergovernmental Panel on Climate Change’s conclusion there is limited scientific evidence linking human-caused climate change to increases in extreme weather, says H.Sterling Burnett.

Alexander’s conclusions are also confirmed by recent documents produced by Heartland Institute Senior Fellow and meteorologist Anthony Watts on the Climate at a Glance website.

Alexander’s paper begins by remarking, “The purported link between extreme weather and global warming has captured the public imagination and attention of the mainstream media far more than any of the other claims made by the narrative of human-caused climate change.”

This is odd because data and analyses from the Intergovernmental Panel on Climate Change (IPCC), the U.N. body that climate alarmists in academic, political, and media circles continually cite as the authoritative source of information on climate change, confirm that “if there is any trend at all in extreme weather, it’s downward rather than upward.

Our most extreme weather, be it heat wave, drought, flood, hurricane or tornado, occurred many years ago, long before the carbon dioxide level in the atmosphere began to climb at its present rate,” writes Alexander.

“Recent atmospheric heat waves in western Europe,” writes Alexander, “pale in comparison with the soaring temperatures of the 1930s, a period when three of the seven continents and 32 of the 50 US states set all-time high temperature records, which still stand today.”

Nor has the IPCC discerned or identified any long-term trend in drought patterns, either in the United States or globally.

And even though rainfall has modestly increased in recent years, there is no evidence floods are becoming more frequent or severe.

Many recent flood events can be traced almost entirely to land-use changes such as channelization, deforestation, the destruction of wetlands, and the building of dams, Alexander notes.
