> The world's climate has been consistent for most of the history of modern humanity That really was not the case. Most major civilizational collapses (Bronze age, Rome) can be linked to climate change (of course premodern societies were generally much more sensitive to even relatively slight changes). |

Note too that the timescale is discontinous, with the scale expanding at 30,000 years ago and in 1850 (173 years ago). The span to the right of 1850 shows 350 years, the span to the left of 1850 shows ~30,000 years, before expanding again to show 65 million years of climate history, back to the extinction of the (non-avian) dinosaurs.
