This paper projects increasing heatwaves – despite all of their data showing the exact opposite.
state-of-the-art climate models project an intensification of heat extremes across the United States and Canada in the upcoming decades and beyond
The paper claims that the heat covered almost one-third of the US, and began around 1930. But their maps and graph show that the heat covered a much larger region, and that summers were hotter from 1910 until 1955.
The National Climate Assessment shows the same thing.
Temperature Changes in the United States – Climate Science Special Report
The vast majority of US states set their all-time temperature before 1940, and all but four set their record with CO2 below 350 PPM CO2.
The vast majority of individual stations set their records below 350 PPM CO2.
Summers were much hotter in the US prior to 1960.
The article claimed poor station coverage in the past, but there were more stations reporting during the 1930s than now.
The heat and drought of the 1930s was not confined to less than one third of the US, it covered the entire planet.

The paper cites a lot of references, and contains lots of mandatory global warming propaganda. But there is no legitimate reason to believe that summers are getting hotter, or will get hotter in the future.
Note that Cohan & All’s paper was published on April 1st …
And the people bowed and prayed
to the neon god they made
listening to the science of climate
Author 2, Gabby Hegerl, has published a number of dodgy temperature reconstructions using Mannian methods
I seem to recall she stated the classic line “If you’re going to make cherry pie, you have to pick some cherries “. I think she was testifying to Congress following Climategate
Jim,
I believe that was Rosanne D’Arrigo, not Hegerl.
Yeah, you are probably right.
I still love the line for its unwitting honesty
[my apologies to Gabby on this particular point]
The masses don’t read history and do’t verify statements, providing fertile ground for leftist propaganda. If you repeat the lie often enough they will come to believe it as fact.
From the journal of Climate Dynamics:
Extraordinary heat during the 1930s US Dust Bowl and associated large-scale conditions
Unusually hot summer conditions occurred during the 1930s over the central United States and undoubtedly contributed to the severity of the Dust Bowl drought. We investigate local and large-scale conditions in association with the extraordinary heat and drought events, making use of novel datasets of observed climate extremes and climate reanalysis covering the past century. We show that the unprecedented summer heat during the Dust Bowl years was likely exacerbated by land-surface feedbacks associated with springtime precipitation deficits. The reanalysis results indicate that these deficits were associated with the coincidence of anomalously warm North Atlantic and Northeast Pacific surface waters and a shift in atmospheric pressure patterns leading to reduced flow of moist air into the central US. Thus, the combination of springtime ocean temperatures and atmospheric flow anomalies, leading to reduced precipitation, also holds potential for enhanced predictability of summer heat events. The results suggest that hot drought, more severe than experienced during the most recent 2011 and 2012 heat waves, is to be expected when ocean temperature anomalies like those observed in the 1930s occur in a world that has seen significant mean warming.

The statements made in 2016 (before NASA-GISS began adjusting away the 1930s heat) was that the 1930s Dust Bowl days were yet to come (if you buy the last sentence of the abstract) – and that the 1930s were hotter than the present era. Now that NASA-GISS has adjusted the data, this paper’s findings are irrelevant. (lol)
Not only can they not predict the world’s climate in the future – they don’t know what happened in the past
“The article claimed poor station coverage in the past, but there were more stations reporting during the 1930s than now”
That alone screams: “this paper is useful only in toilets”
The main thing that comes out of this paper is that we do not really know what caused the temperature extremes of the 1930s (both record cold as well as record heat).
It would be useful to model the impact of a recurrence on global crop yields.
Great Reporting..
