Some comics [0] [1] might be able to get the point across in a way that words seldom do when arguing on the interblags.You're right to call out that we don't know the "ideal" state of anything. I, for one, am excited about higher mean rainfall, more exotic weather patterns, and the changes in flora and fauna we expect to see as a result. Many species we currently know and love (e.g., basically everything interesting off the west coast of the US or north coast of Australia)

cuz it will collapse the global ecosystem and plunge huge populations into climates they're not prepared for.

The article seems to completely forget about climate change. The current pandemic is going to look like a tiny speed bump in a few years when we start seeing regular deadly heat waves, crop failures, and other natural disasters. Billions of people are going to be displaced, and we'll see wars for the remaining livable land. The effects of climate change are all around us already, and they're happening much faster than any of the models predicted:* new research indicates that parts o

Click this XKCD and scroll to the bottom: https://xkcd.com/1732/This is not a normal phenomenon.Earth can accommodate climate change. We're not worried about Earth. Prosperous, free, advanced human civilization is what's at risk here, between disruptions to agriculture and refugee crises the likes of which the world has never seen.

You don't need to reach 3, or 4, or 8 to render swathes of the world functionally uninhabitable. At present trajectories Dubai and Miami will reach lethal wet bulb temperatures within my lifetime.Science refines models, you seem to be under the impression that makes it hysterical. Isaac Asimov might disabuse you of that notion: https://hermiene.net/essays-trans/rela

Sure its not gonna "kill the world", but you can expect a constant inflation of food prices, wars plus tens of millions of refugees due to climate instabilities. It will not eradicate mankind, but it may provoke the downfall of modern civilizations. And then good luck starting from the beginning again after you have depleted all easily accessible basic ressources such as iron or coal.

The evidence is that the Earth is warming so it's not odd that there aren't any dire warnings about it cooling. When it cools suddenly then I'm certain there would be dire warnings.It seems to me that the dire consequences are about the ability of nations to deal with relatively sudden changes. We are no longer at the point where populations can shift easily on a grand scale. Four thousand years ago it was much easier for humanity to shift production of food and seek out new

Thats a bad way to look at it.A better way:The moisture is being sucked out of some places and falling to others. So one area is becoming barren, and another is being flooded. This means a few things:- It is harder to farm. Can't farm when it is flooded, can't farm when it is barren- It is harder to keep fixed cities because the climate changes. Imagine having to move NYC every 10 years. It is far worse when people don't have good infrastructure.- The displacement o

If a third of the world becomes uninhabitable within the space of 3-4 decades, expect the remaining parts to also feel it.

Because if it is indicative of a warming planet (which this particular event may or may not be, although the warming of the planet is beyond doubt at this point), then life for human being is gonna get much worse because we have spent centuries setting up civilization based on environmental conditions which are not true anymore.As a result you will see mass migrations as earlier fertile regions become arid, and people compete for scarce resources, exposure to diseases that populations in a re
