> So the levels aren't the problem, it's the rapidity?

Not what I said. You argued it has been hotter before and it wasn't a problem. I had to explain to you that temperatures haven't changed this fast before, which is a strong argument for the antrhopogenic nature of the current change. It also illustrates the danger of the current phase, since the thriving ecosystems of millions of years ago didn't have to deal with such sudden change.

> I'm in Ohio, USA. Are you from the Arctic by any chance? Maybe Australia? How about Mongolia? Perhaps Brazil? Mozambique? We live and thrive in all of those unique areas. Very narrow conditions indeed...

Don't conflate narrow global conditions with narrow set of landscapes. The holocene has been remarkably stable in terms of climate and civilization thrived due to this stability.

You're clearly arguing in bad faith and I feel no need to engage further
