Michael Mann falsely claims climate kills more people than Covid

When exposed, he doubles down and claims a Bloomberg article w/5 million deaths

Except, that's 0.5m heat deaths and 4.5m cold deaths, with cold⬇️ more than heat⬆️

Pathetic

🧵

Originally, Michael Mann falsely claims

wildfires, droughts, floods, heatwaves, and coastal inundation caused by climate

kill more people than Covid19

No: 2020-21 such climate deaths total 21,500
2020-21 Covid total 18,100,000

Covid 𝟴𝟰𝟬𝘅 bigger

When exposed, he claims WHO says 250K climate deaths

But
1) not from wildfires, droughts etc, as he claimed (malaria, dengue etc)

2) 250,000 not larger than 18,100,000

3) laughably suggests that 𝗲𝘃𝗲𝗻𝘁𝘂𝗮𝗹𝗹𝘆 larger (yes, after 72 years)

After more googling Mann finds confirmatory news story

Only: study shows 4.5m cold+0.5m heat deaths

1) Bloomberg headline wrong: Not from changing climate, but from cold+warm 𝘄𝗲𝗮𝘁𝗵𝗲𝗿
2) Study shows higher temperature→𝗳𝗲𝘄𝗲𝗿 deaths

Oops

Here is the study, it finds that from 2000-19 global temp rise led to 116K more heat deaths, but 283K fewer cold deaths, so overall 𝗳𝗲𝘄𝗲𝗿 deaths

So, maybe not the point Mann thought he was making...

But pesky facts don't get in the way of intrepid professor Mann

Ready to call anyone disagreeing 'deniers' and double down on false claims

Recap:
Originally 840x wrong

Then shifted to just 72x wrong

Now use wrong news article to claim he's right

Here is why he was originally wrong

Pointing to WHO is an entirely different set of deaths, from malnutrition and malaria

And remember, WHO data doesn't show the world dying more, but dying less and less 𝘀𝗹𝗶𝗴𝗵𝘁𝗹𝘆 𝘀𝗹𝗼𝘄𝗲𝗿

See here:
and

And then when Mann googles terrible Bloomberg article claiming 5 million deaths from climate

He ignores:

1) 5 million deaths from 𝘄𝗲𝗮𝘁𝗵𝗲𝗿
2) mostly from 𝗰𝗼𝗹𝗱
3) total deaths 𝗱𝗲𝗰𝗹𝗶𝗻𝗶𝗻𝗴

As even 2nd author of Lancet study says
