This is the problem with believing too much in models. A model can show you anything you want - it's output is only as good as the parameters and algorithms you set it.

Modelling the climate in the next 50-100 years is already extremely difficult and fraught with inaccuracies but we have lots of models and data to extrapolate from, so we do have a crude idea where we're going. But we can't model next years weather with accuracy, just the base trend. Crucially important warning for climate change but limited otherwise.

Modelling out to 250 million years is basically a crock of shit. The tectonic movements are predictable and gross predictions that a pangea arrangement might be warmer may have some validity but modelling the climate and evolution and status of mammals is pure conjecture.

Good thing about modelling that far is you will never have see you model's accuracy being tested. Publish a paper, play into current fears around climate change with an irrelevant prediction about 250million years away, get an article published in the New York times and egos massaged all round.

Make way for dinosaurs round 2.

Crocodiles and sharks just be watching mammals and birds like old tradesmen watching the new apprentice, knowing he aint gonna last a day.

I, for one, welcome our new insect overlords.

That fucking website with its 3 quarter screen popup forcing registration. Fuck new York times and it's bullshitty bullshit.

Republicans: not if I have something to say about it!

Do you still not see it? Republicans claim not to believe in Climate Change because they are all Lizard People!
/s if it isn't obvious enough.

This is the best summary I could come up with:


Alexander Farnsworth, a paleoclimate scientist at the University of Bristol who led the team, said that the planet might become too hot for any mammals — ourselves included — to survive on land.

Dr. Farnsworth enlisted Christopher Scotese, a retired geophysicist from the University of Texas who had crafted the Pangea Ultima model, and other experts to run more detailed simulations of that far-off future, tracking the atmosphere moving over the oceans, the supercontinent and its mountains.

Thanks to the turbulent movements of molten rock deep in the Earth, the volcanoes may release vast surges of carbon dioxide for thousands of years — blasts of greenhouse gases that will make temperatures rocket up.

If global warming continues unabated, biologists fear it will lead to the extinction of a number of species, while people will be unable to survive the heat and humidity in large swaths of the planet.

Wolfgang Kiessling, a climate scientist at University of Erlangen-Nuremberg in Germany, who was not involved in the study, said that the model did not take account of a factor that might mean a lot for the survival of mammals: the gradual decline in the heat escaping from the Earth’s interior.

As scientists begin using powerful space telescopes to peer at planets in other solar systems, they may be able to measure their continental arrangements to infer what kinds of life might survive there.


The original article contains 1,031 words, the summary contains 231 words. Saved 78%. I'm a bot and I'm open source!

If at that point we're not off earth yet we kinda had it coming.

We're not supposed to leave Earth. We evolved to survive and interact with Earth's systems. Death is inevitable. Entropy is our God.

As long as there are still animals that can live on Earth it's the most habitable planet in our solar system

In the geological timescale for the supercontinent to reform, we and mammals would have evolved as well. Humans would evolve into Xenu™©® for all we know.

ourselves included

Um, we are talking 100's of mlllion years, yes?

I guess someone isn't in the beta testing for neuralink 😏

Okay, maybe graphen + light circuits will have infinite cycles of operation and be fine with passive cooling...

And there's experiments with surface-only electron waves tech (what's it's name?), which could work on the potential difference of wind blowing over it.

Sure, there aren’t any heat adapted mammals

Doesn't matter if there's no food or extremely scarce resources.

Losing the plankton in the ocean on top of losing vegetation would also cause oxygen problems, iirc.

One of the planet's mass extinction events was The Great Oxidation Event. Future lizard scientists will study our time period and coin it The Great Carbonisation Event!

Why would that be though? Last time there was a supercontinent it also supported large animals

Please! We can't predict the weather for tomorrow with enough certainty and you want me to believe that we know how it will behave for the next 250 million years?!
