This is borderline climate denial, not "calm and reasonable". If you want to tell yourself that things are somehow gonna be fine, then feel free to go ahead. It just doesn't line up with an absolutely overwhelming scientific consensus.

It is not borderline. It is out-and-out denial. People like that will, ultimately, be personally responsible for collapse when it comes, but they will be better insulated from consequences than their victims.

I denied nothing. I simply stated that climate change is business as usual. Have we as humans impacted it, yes. But we’ll either adapt or die. How is that a denial?

It is downvoted because it is dangerously incorrect. It is not a reasonable opinion, though it is calmly delivered.

Yes, climate has always changed. The current rate of change, caused by mankind, is extreme: https://xkcd.com/1732/

I love the certainty you have. I only wish I could be as certain as you with planet-scale systems.

Which bits are you unsure of? Are you concerned the data regarding historical temperatures is incorrect?
