CNN Goes ‘Mann Overboard’ on Eastern U.S. Heatwave

From ClimateREALISM

Editors Note: This guest essay from meteorologist Chris Martz talks about how CNN uncritically reposted statements from embattled climatologist Michael Mann in an interview discussing summer a heat wave that has been forecast for the eastern half of the United States. The media has been promoting heat wave hysteria nearly continuously for the past two weeks. Mann made some wild claims about the heatwave that Martz completely debunks and falsifies simply by looking at past temperature records for cities highlighted by CNN. Mann, as a “distinguished professor” should have checked the data himself, but instead chose to turn a normal run-of-the-mill summer heatwave into a “climate crisis” without any actual evidence, and CNN posted it as fact, rather than the unjustified speculation that it is.


From Chris Martz on Twitter

CNN’s Brianna Keilar interviewed their number one climate czar, Dr. Michael Mann from UPenn, yesterday, to discuss how this week’s “brutal” and “unprecedented” heatwave is being fueled by global warming and is a taste of our future.

“𝗧𝗵𝗶𝘀 𝗶𝘀 𝗮 𝗴𝗹𝗶𝗺𝗽𝘀𝗲 𝗼𝗳 𝗻𝗼𝘁 𝗼𝗻𝗹𝘆 𝘄𝗵𝗮𝘁 𝗼𝘂𝗿 𝗳𝘂𝘁𝘂𝗿𝗲 𝘄𝗶𝗹𝗹 𝗹𝗼𝗼𝗸 𝗹𝗶𝗸𝗲, 𝗯𝘂𝘁 𝗶𝗻 𝗳𝗮𝗰𝘁 𝗶𝘁 𝘄𝗶𝗹𝗹 𝗹𝗼𝗼𝗸 𝗾𝘂𝗶𝘁𝗲 𝗮 𝗯𝗶𝘁 𝘄𝗼𝗿𝘀𝗲 𝘁𝗵𝗮𝗻 𝘁𝗵𝗶𝘀. 𝗪𝗲 𝘄𝗶𝗹𝗹 𝘀𝗲𝗲 𝗺𝗼𝗿𝗲 𝘄𝗶𝗱𝗲𝘀𝗽𝗿𝗲𝗮𝗱 𝗮𝗻𝗱 𝗵𝗼𝘁𝘁𝗲𝗿 𝗮𝗻𝗱 𝗹𝗼𝗻𝗴𝗲𝗿-𝗹𝗮𝘀𝘁𝗶𝗻𝗴 𝗵𝗲𝗮𝘁𝘄𝗮𝘃𝗲𝘀 𝗶𝗻 𝘁𝗵𝗲 𝗳𝘂𝘁𝘂𝗿𝗲 𝗶𝗳 𝘄𝗲 𝗰𝗼𝗻𝘁𝗶𝗻𝘂𝗲 𝘁𝗼 𝗵𝗲𝗮𝘁 𝘂𝗽 𝘁𝗵𝗲 𝗽𝗹𝗮𝗻𝗲𝘁.”

Mann then goes off on an activist sales pitch, demonizing affordable and reliable energy consumption, which he himself benefits from:

“𝗔𝗻𝗱, 𝘀𝗼 𝗮𝗹𝗹 𝗼𝗳 𝘁𝗵𝗶𝘀 𝗴𝗲𝘁𝘀 𝘄𝗼𝗿𝘀𝗲 𝗶𝗳 𝘄𝗲 𝗰𝗼𝗻𝘁𝗶𝗻𝘂𝗲 𝗽𝘂𝗺𝗽𝗶𝗻𝗴 𝗰𝗮𝗿𝗯𝗼𝗻 𝗽𝗼𝗹𝗹𝘂𝘁𝗶𝗼𝗻 𝗶𝗻𝘁𝗼 𝘁𝗵𝗲 𝗮𝘁𝗺𝗼𝘀𝗽𝗵𝗲𝗿𝗲 𝗮𝗻𝗱 𝘄𝗮𝗿𝗺𝗶𝗻𝗴 𝘂𝗽 𝘁𝗵𝗲 𝗽𝗹𝗮𝗻𝗲𝘁. 𝗧𝗵𝗮𝘁’𝘀 𝘁𝗵𝗲 𝗯𝗮𝗱 𝗻𝗲𝘄𝘀. 𝗧𝗵𝗲 𝗴𝗼𝗼𝗱 𝗻𝗲𝘄𝘀 𝗶𝘀 𝘄𝗲 𝗰𝗮𝗻 𝘀𝘁𝗶𝗹𝗹 𝗱𝗼 𝘀𝗼𝗺𝗲𝘁𝗵𝗶𝗻𝗴 𝗮𝗯𝗼𝘂𝘁 𝗶𝘁; 𝘄𝗲 𝗵𝗮𝘃𝗲 𝘁𝗼 𝘀𝘁𝗼𝗽 𝗺𝗮𝗸𝗶𝗻𝗴 𝘁𝗵𝗲 𝗽𝗿𝗼𝗯𝗹𝗲𝗺 𝘄𝗼𝗿𝘀𝗲 𝗯𝘆 𝗴𝗲𝘁𝘁𝗶𝗻𝗴 𝗼𝗳𝗳 𝗳𝗼𝘀𝘀𝗶𝗹 𝗳𝘂𝗲𝗹𝘀.”

Someone should tell these people that this is what a glimpse of SUMMER looks like. There is nothing unprecedented or all that unusual about this heatwave. Not by summer standards nor by June standards.

Let’s look at the NWS forecast through Sunday for the same cities CNN plotted on their WSI graphic (seen above) at the 12-second mark in the video:

He has made a lucrative academic career out of a mathematically bogus hockey stick PhD thesis that even included his ‘proxy/thermometer splice Nature trick’.

Typifies bad ‘climate science’. Two of my other personal favorites are Dessler, who claimed in a 2010 paper that an r^2 of 0.02 proved positive cloud feedback. r^2 0.02 means no meaningful statistical correlation. Sterling claimed polar bears were threatened by loss of summer Arctic sea ice. Polar bears consume (depending on which subpopulation) between 70 -85% of annual caloric intact during the spring seal whelping season. NOBODY ever claimed global warming would diminish Arctic spring ice after a total dark and freezing Arctic winter.

Bad math, bad stats, bad biology. Nothing good in ‘settled climate science’ anywhere. There is even bad basic physics—methane is a GHG in the lab dry atmosphere, but not in the real world wet atmosphere of a planet covered 71% by water. Yet we are supposed to eat bugs rather than beef because of absurdly bad real world physics.

Not to mention that methane has an atmospheric life of 5-10 years during which it is broken down into CO2 and H2O.

Wasn’t the estimated polar-bear population about 5,000 when former Vice President Al Gore made his pronouncement that the polar bears would become extinct, and their populations have been decimated to the current estimate of 35,000?

That 5000 number I believe was in the 1950s. So the bears were already increasing in number when ManBearPig made his initial proclamations.

Yes, the Media is constantly fear-mongering about the heat.

And as was noted in the article above, not one record temperature was set in this heatwave. It was warmer in the recent past than it is today. But the Climate Alarmists want us all to believe we are living in the “hottest year evah!”

it’s all a pack of lies. Dangerous, destructive lies.

June 20, 2024 2:41 pm

They haven’t got anything else. All their past climate ‘predictions’ were wrong. And they forget past weather records are easily retrieved via the internet, as here.
So alarmists like Mann just continue to make fools of themselves. Ridicule is richly deserved.

BTW, it was this post’s Chicago heatwave of 1988 that finally convinced me to spend really big bucks on our then Chicagoland ‘mansion’ full AC retrofit to a three story 5br/5full+two partial(ground floor powder room, full basement) bath brick house built in 1921. Massively complicated project, but ultimately successful. Cool is cool in a heatwave.

CNN is hardly the only network to make a big deal out a typical North American summer heat wave because Canada’s CBC will never fail to jump on the climate alarmism bandwagon either. On the one hand the CBC is describing the warmer-than-normal weather in eastern Canada in near-catastrophic terms while slyly avoiding to mention that in the West, temperatures are either normal or slightly below with above-average rainfall. It also is cautioning that such heat will make students unable to learn—as though these conditions will endure for much of the year, especially in January It’s exaggerations like this that costs the mainstream media much of their credibility.

“It also is cautioning that such heat will make students unable to learn” That must be why students in hotter climes don’t get good grades. 😉

June 20, 2024 2:49 pm

Around 4.6 million people die each year from cold or cool weather compared with about 500,000 that die each year from warm or hot weather.

Cold or cool weather causes increased heart attacks and strokes because in cold or cool weather the body constricts blood vessels to conserve heat and this raises blood pressure causing increased strokes and heart attacks in the cooler months.

I think they do their best to get local forecast right. That’s good.
But then they do their best to give a false impression that it’s due to Man caused “Climate Change”.
I wonder how many weather stations still include the record highs and lows for the day?
(Other than implying a record a record might be broken then ignoring it if wasn’t.)

One of our local radio stations, KNX (the CBS affiliate, so MSM), broadcast yesterday that temperatures would be between 2F and 20F hotter today. Their “local” forecast area stretches from the far west of the San Fernando Valley to Palm Springs, and from the north of the San Fernando Valley to the San Diego county line. It includes beaches, heavily-urbanized areas, the Hollywood Hills and the San Gabriel Mountains, and peaks over 11,500 feet high (> 3500 metres) west of Palm Springs. The 2F increase was to be near the beaches, while the 20F increase was to be around Palm Springs, in the desert.

The hottest temperature recorded in Ohio was 113 degrees Fahrenheit on July 21, 1934, near Gallipolis.

And, speaking of heat waves, for my little spot in central Ohio (Columbus area),

20-Jul                   101        1934 (tied the 1930 record)
                                          1930
21-Jul                   106        1934 (all time record high)
22-Jul                   104        1901
23-Jul                    99         1933
24-Jul                   102        1934
25-Jul                   104        1934
26-Jul                   102        1934

For those 7 days, July 20 to July 26, 5 of them set (with one tie) record high for the day. One of them was also the all time high for the area.

Fairmount, Indiana today, the National Weather Service issued (emphasis mine):
Excessive Heat Warning for Grant County

Effective Jun 20, 2024 at 2:16 PMExpires at Jun 22, 2024 at 8:00 PM

Excessive Heat Warning issued June 20 at 2:16PM EDT until June 22 at 8:00PM EDT by NWS Northern Indiana

* WHAT… Dangerously hot conditions with peak heat index values of 95 to 102 through Saturday. Low temperatures in the 70s at night will provide little relief from the heat.

* WHERE… Portions of northern Indiana and northwest Ohio.

* WHEN… Until 8 PM EDT Saturday.

* IMPACTS… Extreme heat and humidity will significantly increase the potential for heat related illnesses, particularly for those working or participating in outdoor activities.

* ADDITIONAL DETAILS… Heat stress increases with the number of consecutive hot days. The effects of heat are most impactful for more vulnerable urban populations.

Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Young children and pets should never be left unattended in vehicles under any circumstances.

Take extra precautions if you work or spend time outside. When possible reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear lightweight and loose fitting clothing when possible. To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency! Call 9 1 1.

It’s summer in Indiana, so of course it can get hot. Anyone who has lived a few years knows to expect it from time to time and how to deal with heat. NWS, OSHA, CDC, etc. have become the nanny state to promote the myth of excessive, extreme heat! This is all in lock step with the new strategy of fixation with EXTREME and false attribution. They are trying to convince people that weather never happened before today. I’m 70 years old and regularly go running in temperatures above 90F with heat indices above 100F. Acclimate and hydrate!

Yes, the written temperature records refute the heatwave scaremongering. It was as warm or warmer in the Early Twnetieth Century as it is today. Nothing unprecedented weatherwise is going on today. What is going on is a whole lot of climate change scaremongering.

June 21, 2024 12:22 am

From the BBC, “Climate change made US and Mexico heatwave 35 times more likely”. “The World Weather Attribution (WWA) group studied excess heat between May and early June, when the US heatwave was concentrated in south-west states including California, Nevada and Arizona. 
Extreme temperatures in Mexico also claimed lives during the period.
Such attribution studies take some time to complete, so it is too soon for scientists to say how much of a role climate change is playing in the current heatwave stretching from the centre of the US through to the north-east and into Canada.
In their new report, the scientists said such a heatwave was now four times more likely than it was in the year 2000, driven by planet-warming emissions.
Many extreme weather events including heatwaves are becoming more frequent and intense as a result of climate change, experts say.
“The results of our study should be taken as another warning that our climate is heating to dangerous levels,” said Izidine Pinto, Researcher at the Royal Netherlands Meteorological Institute.”
