If enough climate systems collapse, lots of existing farms will no longer be viable. That means famine and migration, which means war, which means lots of death. I don't know anyone who thinks we'll see extinction (outside of possible "hothouse earth" scenarios, where we become a second Venus) but societal collapse is definitely on the table. Saying this is "not scientific" would just be you not understanding the science.

"Climate conspiracy"? Like you, mean, the conspiracy of climate scientists to publish facts to the best of their understanding?

I don't know what exact strawman you're arguing against, although I'm sure you can always find some idiots saying something like what you say. But scientific consensus has long been that it will lead to increasingly extreme weather and mass extinction, which we seem to be on track for. Of course, we can't know for sure what the consequences are untill we do the experiment, which in this case means potentially destroying large sections of the biosphere and living with increasingly destructive weather patterns. Surely that risk is worth at least legislating that hyperscalers need to spend some of their billions on solar panels?

It doesn't have to end the humanity itself. My favorite city being underwater because it's too expensive too pump the water out is already bad enough.

End humanity, maybe not. Causing very painful social changes, however, is absolutely on the cards.

It’s anxiety about tipping points more than conspiracy theories. If you look at the figures in the various scenarios without even factoring them in: hundreds of millions to billions face food and water insecurity. You may be insulated enough from the direct effects but what about what they trigger? Already even our wealthy societies are being strained by rising food prices, extreme weather, and dysfunctional migration.

We don’t know exactly what the tipping points would lead to but we do know it would be some degree of a more severe and abrupt decline across the board.

> The left wing version of climate conspiracy is that climate change will end humanity itself.

That is unrealistic, but also not what a conspiracy is. It’s also a red herring, as nobody serious is claiming that. They are talking about civilisation changes, which we are already seeing.

At some point you have to engage with the arguments besides shouting "no, it’s you".
