The research study that concluded this heat wave event was "virtually impossible" without climate change does not provide an analysis of all "heat dome" events from the past 2,000 years -- instead focusing on model data since 1950. 
Huaynaputina erupted in 1600 and has since gone quiet. 
ABC News reported the same information, including it in their headline. 
Rubin's column was tasked with marketing climate change as the proximate cause of the LA fires, and the vast majority of media and Democrat politicians have jumped aboard the bandwagon. 
No observations were used in the attribution study. Instead, reanalysis and gridded precipitation were used. Obviously that's a problem when using pre-satellite data.
"climate change has also increased the frequency and severity of extreme weather" 
Proposed new Saffir Simpson Scale: 
The claim is that the "off-the-charts" warm Arctic right now is causing cold air to plunge into Texas.
Unfortunately, the forecasts are trending toward the full load of Arctic air dumping on the southern Plains and Texas with a slow but steady surge into Great Lakes. 
Looking back at the El Nino of 2015-16, the typical global cooling until mid-January was disrupted by a significant warming episode. 
Don't expect any capable scientists to bother reviewing this "super-rapid" climate attribution research article.
The Dust Bowl of the 1930s and 1980 stand out as so exceptionally hot, many decades ago, that no one would say without laughing that the recent July in Texas was unprecedented. 
The 40 Trillion gallons of water vapor in the stratosphere represents an unprecedented amount injected in the stratosphere. 
Note, there is every indication that longer, more frequent, and intense heat waves may be occurring and are expected to occur in the future. 
No evidence provided that Arctic is forcing the tropics -- just believe me. Seriously.
