Little evidence of changes in extreme weather trends

New IPCC attribution statistics are distorting observational evidence

London, 27 July – A new paper from the Global Warming Policy Foundation finds that the IPCC’s recent shift in methodology has led to misleading claims about changes in weather extremes.

The review, from physicist Dr Ralph Alexander, finds that IPCC claims that many of these weather extremes are increasing significantly are largely unsupported by observational evidence.

Ralph Alexander: Extreme Weather: The IPCC’s Changing Tune (pdf)

According to Dr Alexander:
“On almost every kind of extreme weather, with the possible exemption of heatwaves, the evidence for significant changes is scant. But the latest IPCC report has introduced novel ‘attribution’ statistics and now insists that things are getting worse. It’s yet another case of scientists trying to scare the public into compliance.”

Dr Alexander’s paper looks at:
– droughts
– floods
– hurricanes
– tornadoes
– wildfires
– hot and cold extremes
– coral bleaching.

He concludes that:
“The mistaken belief that weather extremes are worsening because of climate change is more a perception, fostered by media coverage, than reality. The IPCC’s new statistical method is playing an unworthy part in bringing this sorry state of affairs to pass.”

GWPF invited the Royal Society and the Met Office to review this paper, and to submit a response to be published as an appendix to it. No reply was received.

BBC Exaggerate Drought Claims

To compare this year with 1976 is really quite mendacious, as the latter was much, much drier. And as the BBC’s own chart shows, there have been eight other years since then with similar rainfall levels to this year. Indeed, in England, as opposed to England & Wales, both 1996 and 2010 had drier starts to the year).

In other words, this year is not an exceptional event, merely something you expect to see every few years or so.

And if you go back through the full Met Office record to 1836, we can see again that there is nothing at all unusual about this year.( Indeed, all of the really dry years occurred in 1976 and before:

Climatologists Embarrassed: Increase In Global CO2 Levels Accompanied By Arctic Sea Ice Growth!

by P. Gosselin, July 26, 2022 in NoTricksZone

Today we look at the polar ice caps, which the global warming wingnuts claim is the canary in the coal mine and predicted earlier they’d melt and collapse. For example, Al Gore warned the Arctic ice would disappear by 2014.

While CO2 has gone up, Arctic sea ice has RISEN over past decade

But we have a big surprise. First we examine the Arctic sea ice extent so far this summer. Has it melted away like Al Gore said it would?
