I’m a Dutch science journalist, and I watched @climatethemovie.

It’s full of crap. 😂

Here’s my step-by-step walkthrough, translated by popular request! 👍

Enjoy the ride! 🧵

2/ ...After a fairly ok summary "it was much warmer in prehistoric times than today" (sure, but who cares?)

Yup: first lie. ⚠️
This graph, of temperatures over the past 2000 years:

3/ ...It’s a well known reconstruction, by Ljungqvist. 👇


Except... it’s TWENTY YEARS OLD. 🙄 jstor.org/stable/40930999

4/ ...Today, we know that the ‘warm’ Medieval and Roman periods from the graph were actually REGIONAL.

Current warming (right) is EVERYWHERE:

5/ ...Modern reconstructions of temperatures since the year zero AD look more like this:

(see: ) nature.com/articles/natur…

6/ ...Plus, the documentary LEAVES OUT the last bit of
Ljungqvist's graph.

Today, it would look like this 👇:

7/ ...Hey! It’s the good old Central England Temp Record!

A classic, among climate skeptics. 🥳

Because it appears to show there has been *hardly any warming* since, say, 1650...

Until you take a closer look...📷

8/ ...A few things aren't right.

First of all, the real graph VERY CLEARLY shows warming is indeed happening...

9/ ...And secondly: Central England is of course just a pinprick on the map. Lots of regional influence here.

Here’s the AVERAGE of measurements, on the Northern Hemisphere 😏:

10/ ...It doesn't get better than this. 🥳👇

Peak climate scepticism: "What we see is simply a recovery after the Little Ice Age". 🤷‍♂️

Um, nope.

11/ ...The Little Ice Age was probably the sum of several natural factors:
sun ☀️
volcanism 🌋
maybe sea current 🧜

And those factors are simply NOT doing the heavy lifting now.

Actually, the climate should cool DOWN a bit. 👇

12/ ...Here's another nice one.

"In Central Park, temperatures haven’t changed since 1940! The normal temperature fluctuations are much greater." 🤔

No shit, Sherlock. 😂

13/ It’s misleading. Central Park is hardly representative of the US.

Here's the national statistics.
Seems the world is warming up in the US too. 🥳

14/ ...This also gives MORE temperature records.

Here’s a beautiful time series from @Datagraver 🏆, in my country. Of the number of daily temperature records.

Fewer and fewer COLD records each year. And more and more HEAT records...

(It's getting boring, I know. But hang in there! Just grab a nice tidbit here and there 🥳👍)

15/ ...Here's the next box to tick on the climate bullshit bingo card:

"The earth isn't warming up! It's just because the thermometers are more and more in the city!" 🥳

16/ ...Sure.
Then those buildings and parking lots have also been built… at sea? (blue) 🤔

17/ (The fact that land masses heat up more than the sea is simply because the oceans cool themselves, by evaporation.)
carbonbrief.org/guest-post-why…

18/ ...And of course, scientists DO COMPENSATE for urban heat, by comparing their measurements with rural areas (green 👇).

Interestingly, it often doesn't even matter that much.

Urban weather stations are often located in parks, etc.

19/ ...Aaaaand, yes!! "CO2 is plant food" 🌿

Anyone Bingo yet? 🥳

(The point, of course, is that climate change is about the 46% of our CO2 emissions that is *NOT* absorbed by nature, and ends up in the atmosphere.)

20/ ...Even about something that is TRUE (plants absorb CO2), the documentary manages to get it wrong.

Wut? Did “all life nearly got extinct” during the Last Glacial Maximum? 🤔

21/ ...The mighty mammoth begs to disagree. 😂

(Not to mention all prehistoric life in the tropics back then)

22/ ...Plus, it’s not like we’re running out of CO2. 🙄

Here’s the CO2 over the past 800,000 years.
Currently, we’re at 420 ppm.

23/ Another classic:

"There is a correlation between CO2 and temperature, but the other way around: CO2 only rises after temperature." 🤔

This is actually true. But only PARTLY.

24/ ...Here’s CO2 (black) and temperature (blue), last 800,000 years. 👇

What usually happens:
Sun pokes up the system a bit => earth warms up => CO2 is released => warming accelerates. 💡

Often, CO2 is a *feedback*.

25/ ...But of course that does NOT mean that CO2 isn’t capable of warming the earth!

Just think of your house. Sun ☀️ often warms it up.
But that doesn’t mean your thermostat is useless.

There is simply *MORE THAN ONE WAY* to heat a house! 🥳

26/ ...Probably the best geological evidence for warming by greenhouse gases: the ‘PETM’, 56 million years ago. 👇

Methane erupted from the sea => VERY fast warming. 🥳
southampton.ac.uk/news/2022/03/a…

(Phew, almost half way through! Keep up!)

27/ ...Ok, another nice lie.

"Most of the warming occurred before 1940. And most of the CO2 emissions were AFTER that!"🤥

Not quite. 😏

28/ ...This is because the left graph is simply WRONG (see this thread, 15-18).

And the right graph starts at 1750, giving the impression the line rises more steeply...

29/ ...Here are the actual data.

As you can see: CO2 emissions and temperatures rise nicely in tandem.

30/ ...Another classic: the 1930s were very warm! Dixit Steve Koonin.

Pants on fire. 🤥

31/ ...This was the case in *America* 👇, where due to poor land use there was the Dust Bowl drought...

32/ ...On a global scale, there wasn't much going on in the 1930s.

33/ ...Here's another one straight from the Climate Sceptic Bingo Card:
"It cooled down after the Second World War!" ✅

That's right. Except, it has nothing to do with CO2...

34/ ...The slight (!) decline was due to massive air pollution. Sulfur in particular blocks sunlight.

35/ ...Actually, I was surprised when I put the data together. 🤯

Top: sulfur emissions. Below: temperature.

The cool period EXACTLY matches the peak in sulfur emissions. 😳

36/ ...And of course, this one is INEVITABLE.

"Climate models overestimate warming." 🥱

38/ ...What they show you, is John Christy's infamous, misleading graph. 👇

(For a detailed explanation why it's misleading, see ) shorturl.at/egimJ

37/ ...Meanwhile, here's the reality. Actual warming vs models. (h/t @carbonbrief)
You can easily check this yourself.

39/ And there’s… John Clauser!

A Nobel Prize Laureate! 🏆

Ok, for research into… quantum entanglement. 😂

40/ ...When I recently seriously asked Clauser to substantiate his claim, he couldn't provide it.

Worse: it turned out he didn’t *have a clue* about climate science. 🤦‍♂️

Here is my report: wp.me/p1hd3G-xA

42/ Ok. So to summarize:

✅ There is no global warming;
✅ Global warming, which isn’t there, is NOT caused by CO2;
✅ CO2, which doesn't cause global warming that isn't happening, doesn’t come from humans. 🤔

So: what DOES cause this global warming that isn’t happening?

43/ “It must be cosmic particles creating extra clouds!” 📢

Well, no.
What they forgot to tell you is that the number of space particles actually DECREASES. 🙄

44/ “It's the sun!” 📢

Including an infamous, flawed sun reconstruction.

(see
) realclimate.org/index.php/arch…

45/ ...So, here's the data from NASA.
They happen to do some solar science, every once and a while. 🙄

No connection there...

47/ ...Ok, extreme weather’s up next. ⛈️
It actually starts with a correct observation by @RossMcKitrick

48/ ...After which the documentary immediately falls back into Trick Mode again. 😖

"There used to be a lot more heat waves!" 📢

This was the US Dust Bowl, remember?

49/ ..."Summers didn't get warmer, winters got milder" 🙄

Hey, it’s the Middle England Temperature series again!

50/ ...Of course, if you zoom out to the ENTIRE Northern Hemisphere, summers are indeed getting WARMER. 👍

51/ ..."The number of wildfires decreased this century!" 📢

True.

But that’s because people (in the tropics in particular) BURN LESS NATURE, according to the study.
… agupubs.onlinelibrary.wiley.com/doi/full/10.10

52/ "The number of US wildfires is decreasing!" 📢

You betcha. It’s the Dust Bowl again. 🔥

More relevant is the INCREASE in US wildfires over the last 50 years.
Due to, among others, longer fire seasons. ⚠️

53/ "There’s no increase in hurricanes!" 📢

True, and as usual, misleading.

There are other increases. 💨
Such as faster increases in hurricane STRENGTH. Remember Acapulco? volkskrant.nl/ts-bf86526e/

54/ "Antarctica didn't get any warmer!" 📢

No, not OVERALL. 🤦‍♂️

But the *edges*, which prevent the ice glaciers from slipping away, became more unstable... 🙄
nature.com/articles/s4155…

55/ Only at the VERY END, the truth comes out. 👇

This documentary is NOT about climate science at all. 😐

It's about politics.

The boring, old stuff: right vs left. 🥱

56/ “No big government!”

Of course, feel free to debate this 👍
But shall we leave the SCIENCE out?🙄

Needless to say, many of these folks are involved in Big Oil...
(h/t @thedisproof)

59/ Anyway, (very) long thread short: lies, lies, lies. 🤦‍♂️

Putting out pathetic propaganda movies like this silly documentary just doesn't help. 😖
