Why do we always have to end up with this false dichotomy? Why is it so hard to accept that a) yes the climate throughout the history of our planet (at geological time scales) had a lot of variation and humans didn't live during an average climate b) it's reasonable to worry that the climate deviates quickly and strongly from what it was throughout the history of humankind? Why do these two points need to be opposed to each other? The timescales are so utterly incompatible. Is it because people struggle to understand what a million years is? Let alone a hundred million years.
