It's curious that HNers purport to be...smart, yet this comment is heavily downvoted.
Climate has changed before man. Climate will continue to change.
Beyond that, our understanding of our impact is nonexistent and naive. I have to laugh at the hyperfocus on CO2 as if the planet doesn't have a use for it already.
- bryanlarsen 3y agoNever 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.
- willcipriano 3y ago> as far as we can tell. We can't tell very far.
- bryanlarsen 3y agoUncertainty makes it even more important that we don't change the climate.
- ThunderSizzle 3y agoClimate changes, and you can't change that. Whose to know if its because of you or because of nature?
- bryanlarsen 3y agoIf the rate of change is unprecedented, one answer is highly likely.
- wolverine876 3y ago> 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.
- overstay8930 3y agoThe only person literally making things up here is you > 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 3y agoAre you claiming that the Permian-Triassic and Triassic-Jurassic extinction events didn't happen, or that they weren't coincidental with rapid climate changes?
- karmakurtisaani 3y agoCertain portion of HNers certainly is not that smart, judging from the ever present climate change denialism.
