Manmade Global Warming - New Extremes, page-9449

Jops, just because you want to remain a Muppet of Denial, does that automatically mean you have to discard all critical thinking faculties? I guess so.

hence your clueless comment about cherry picking locations.

The Japanese Meteorological Agency would be remiss in not reporting that the Northern Summer just gone was for Japan the warmest on its records. That's what meteorologists do.

but surely you can see a likely motive for @birdman29 drawing attention to the record high US heat wave index in the 1930s in the lower 48 was to moderate concerns about the current global warming being an existential threat. If we survived such warming previously, why worry now.

US-based meteorologists Jeff Masters and Bob Henson addressed this exact issue in an article published mid July on Yaleclimateconnections.org.

extracts from their article appear below this photo showing the grim reality of the US Dust Bowl of the 1930s.


MASTERS & HENSON

"Why were the 1930s so hot in North America?

"Climate skeptics sometimes point to heat records from that decade to dismiss the reality of global warming. They’re leaving out crucial context.

"Those who’ve trawled social media during heat waves have likely encountered a tidbit frequently used to brush aside human-caused climate change: Many U.S. states and cities had their single hottest temperature on record during the 1930s, setting incredible heat marks that still stand today.

"The critical context that’s typically left out is that the 1930s were the decade of the Dust Bowl — the grim result of relentless overplowing of the Great Plains followed by natural oceanic cycles that favored a multiyear drought, which coincided with the Great Depression.

......

"Three multi-year periods of drought unfolded between 1928 and 1942, with virtually no break in between.

"Much of the topsoil across the central United States simply blew away during those nasty years. The bare landscape allowed for maximal warming from the summer sun, which in turn helped reinforce the deep atmospheric heat that prevailed. Day-to-day weather patterns sometimes pushed the dust and heat all the way to the East Coast.

"How the Dust Bowl teamed up with natural oceanic cycles to create all-time record heat"

"There's ample evidence that the heat of the 1930s was partially the result of the parched landscape that itself was stoked by overeager planting and plowing.

"Richard Seager of Columbia University and colleagues found through computer modeling that the landscape degradation of the Dust Bowl interacted with an ocean-forced drought, intensifying the hot pattern and shifting it poleward. And a 2022 modeling study led by Gerald Meehl of the National Center for Atmospheric Research found that the Dust Bowl landscape may have helped to propagate heat extremes across other parts of the Northern Hemisphere.

"1936 heat records"

"The heat was especially brutal during July and August 1936, as chronicled in detail by extreme weather historian Christopher Burt in a 2018 write-up at Weather Underground.

"Dozens of U.S. states and cities set all-time high temperatures (i.e., the highest readings ever officially observed at a given site). The heat extended into south-central Canada, where Winnipeg, Manitoba, soared to its still-standing all-time high of 108 degrees Fahrenheit.

"Below are a few of the still-standing all-time highs set or tied in July 1936 at major U.S. cities:New York City, New York: 106°F (July 10)Baltimore, Maryland: 107°F (July 10)Columbus, Ohio: 106°F (July 14)Louisville, Kentucky: 107°F (July 14)Des Moines, Iowa: 110°F (July 25)Minneapolis, Minnesota: 108°F (July 14)Bismarck, North Dakota: 114°F (July 6)Omaha, Nebraska: 114°F (July 25)."
