The Texas heat wave of 2011 was 20 times more likely to be tied to human-induced warming than to natural causes, said Wuebbles.
Scientists Detail Severe Future Impacts of Climate Change: Scientific American
There is no evidence in the temperature record to support this claim. The three worst heatwaves in Texas history all occurred before 1935.
The four hottest years in Texas all occurred before 1955.
It is easy to see why Hayhoe and Dessler ignore the record prior to 1970.
I emailed this podt to Dr Wuebbles and asked him to defend his statement…
“I was quoting the series of papers by Peterson et al. in the Bulletin of the American Meteorological Society in 2012. One obviously cannot just use temperature as a basis for this (although the presentation by John Nielson-Gammon was also compelling that the heat wave -drought of 2011 in Texas was way outside the norm over the las century). The analyses of this event are based on detailed analyses of the special event and how human-induced cliamte change could have influenced it. In what you present below, you are confusing the science and what it is saying about recent overall trends over the larger scale versus what occurred at a local scale. By the way, in the National Cliamt eAssessment we compare all trends relative to the 1900-1960 time period to make sure we are really capturing long term trends correctly as we examine what has been occurring over the last 5 centuries. So, your subject of “wrong again” is way off base.

There you go, a wave of his hands an it all goes away.
Don, Don, Don… Peterson et al came to their conclusions how?
“While the report includes three examples of the odds-based attribution analyzes discussed earlier, the challenges of running models and analyzing data in time for this report have meant that only the final analysis (of the cold UK winter of 2010/11, section 8) has the climate model simulations available to explicitly calculate the change odds attributable to human influence.”
Models. Any empirical evidence? Or just GIGO grantologist wet dreams? No?
Models are fun to play with, but when serious scientists want to discover if something is unusual or unprecedented, they look to the historical record and do not pursue fantasies. Steven has devoted entire sections of his site to the historical record, I suggest you read it.
“The Texas heat wave of 2011 was 20 times more likely to be tied to human-induced warming than to natural causes, said Wuebbles.”
Yep, we have heard that one before…

Warmism is a belief that weather is unprecedented. Cave men had a better grasp on reality, at least they blamed it on the gods. 😆
Interesting. What’s the source of your data?
