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.
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.

No daily records are in [the] forecast for any of those locations. This week’s heatwave does not compare to those of June 1936, 1944, 1953 or 1988.
Completely and totally ignorant of our weather history. Clowns.
Mann is both sloppy and shameless.
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.
The math/stats/physics weren’t just bad, they were intentionally bad, to create a narrative under which the world could be controlled.
Every year before summer starts, I turn off notifications from all media sources to avoid the incessant barrage of heat-disaster fearmongering.
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.
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. 😉
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.

Mann overboard!
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.
Historical state records reveal CNN’s and Michael Mann’s climate scam
Record Temperatures
Illinois: 117 F July 1954 – this weeks high: Chicago 95 F
Missouri: 118 F July 1954 – this week high: St Lous 96 F
Oklahoma: 120: August 1936 – this week high: Oklahoma City 90 F
Georgia: 112 F August 1983 – this week high: Atlanta 93 F
District of Columbia: 106 F July 1930 – this week high: 92 F
When did 90F become hot? I remember plenty of 100F summer days, without AC. We’ve become whimps.
The first time I experienced AC was in the dormitory at college.
You had air conditioning. You were lucky.
Only we deniers actually have memories. The CAGW / CACC crowd have not got any memories left, and don;t know how to look anything up on the Internet.
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.
I wouldn’t look to Mann or CNN for climate news. Neither know what they are talking about. Pay no attention.
Yes, anyone who uses the term ‘carbon pollution’ to describe CO2 should be summarily ignored.
The problem is, a lot of people do. So the brainwashing/gaslighting goes on and on.
Oh My! A heatwave in summer in the midwest and the east coast. What will we do what will we do? It’s an existential crisis CNN tells you over and over as if its news.
90 or so degree.. how is that a “heatwave” ?
You have to ignore the definition of “heatwave” and just speak colloquially.
It’s a heatwave in areas that aren’t used to it. They would call it that in the Pacific Northwest. But not in Northern VA where I grew up.
South Dakota highs for 20 Jun 24 are 60 to 65 degrees F. 20 degrees below normal — the world is coming to an end.
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!
Heat index.. just another SCAM to scare to ignorant and the AGW cultists… oh wait.. same thing
Yes, if the regular temperature isn’t high enough, they start showing the heat index numbers.
It is a valuable social service to remind people of how to cope with higher (and colder) temperatures.
It is NOT a valuable social service to scare the hell out of people while giving the reminders.
The temperature records for 1934 and 1936 make this look like the Potemkin Village that it is.
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.
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.”
https://www.bbc.co.uk/news/articles/czvvqdg8zxno
“Many extreme weather events including heatwaves are becoming more frequent and intense as a result of climate change, experts say.”
That is simply not true. The evidence does not support this scaremongering. There is no evidence extreme weather is getting more extreme or more frequent.
We live in southern California. We have not experienced any extreme heat. In fact, spring weather just arrived about a week ago. Total rubbish.
It’s not uncommon to have heat waves in late June, the longest days of the year. I recall many of them, having worked outdoors for the past 50 years.
From the article: “Presidential Distinguished Professor”
What the heck is a “Presidential Distinguished Professor”? Is this an official title?
Does Michael Mann go around referring to himself as a Presidential Distinguished Professor?
Pretty Dumb Putz is more like it.
Probably the President of the University of Pennsylvania.
Mann is liar of the first magnitude.
If you are so inclined, Chris Martz is a good follow on X (formerly Twitter). He is constantly engaging climate alarmists with clear, concise and data supported arguments against the breathless, emotion filled garbage thrown at him.
Slightly off topic. On 17th Feb 2022 Liz Bentley, Chief Exec. of the UK Royal Meteorological Society told BBC Radio 4’s World at One programme.
“If you look back over the last,say, 50 years there isn’t a compelling trend that we’ve seen in the amount of storminess we get in the UK” and
“we are not seeing any significant changes or trends within the number of storms or maximum wind gusts over the last 5 decades”
Then it has all been since 18th Feb 2022.
“𝗽𝘂𝗺𝗽𝗶𝗻𝗴 𝗰𝗮𝗿𝗯𝗼𝗻 𝗽𝗼𝗹𝗹𝘂𝘁𝗶𝗼𝗻 𝗶𝗻𝘁𝗼 𝘁𝗵𝗲 𝗮𝘁𝗺𝗼𝘀𝗽𝗵𝗲𝗿𝗲”
And, he calls himself a scientist. Charlatan would be more accurate
Supernovas pump carbon pollution into their galaxies, along with all the other elements they create.
It’s an environmental pollution disaster, supernovas are. Stop limiting your pollution outrage to the earth. We are all citizens of our galaxy and there is nothing you can do to change that.
Did you really read my comment? Obviously not.
