Astroids, suns exploding, super vulcanos etc these are actual potential extinction level events. Things that have actually been demonstrated to happen without human intervention. “No known” is what you are looking for. There are no known demonstrated consequences of climate change that we dont know how to deal with.
More people are saved each year by human technology than die from it.
Other people are giving new arguments each time. You're the one repeating assertions.
> There are no known demonstrated consequences of climate change that we dont know how to deal with.
It feels like you're arguing “and therefore we shouldn't deal with it”.
We can speculate all we want that means nothing.
With regards to doing something about "it" what demonstrated consequences of climate change is it you mean we don't know how to deal with? I never claimed we shouldn't deal with it, just that it's neither existential nor something we can't handle.
On the other hand, it is the opinion of astronomers that "no known asteroids currently pose any significant threat to Earth."
