Never has global climate changed this quickly, as far as we can tell. Usually changes this big take tens of thousands of years, and they're handled fine-ish. A couple of times it has happened over centuries and that resulted in mass extinction. Over decades? Unprecedented.

> A couple of times it has happened over centuries and that resulted in mass extinction.

You just said, without proof, that all (apparently 2 according to you) rapid climate changes have resulted in mass extinction events.

You cannot fight for change if you look like an idiot.

[bryanlarsen]

Are you claiming that the Permian-Triassic and Triassic-Jurassic extinction events didn't happen, or that they weren't coincidental with rapid climate changes?

We can't tell very far.

[bryanlarsen]

Uncertainty makes it even more important that we don't change the climate.

Climate changes, and you can't change that. Whose to know if its because of you or because of nature?

> Whose to know if its because of you or because of nature?

There is a lot of research over decades into that very question, and it overwhelmingly points to humans as the main cause.

If the rate of change is unprecedented, one answer is highly likely.
