Yeah; by the time we are at 3.4C (the bottom of that range), we're already to the point where a large percentage of people are climate refugees. In addition to many currently-inhabited places being too hot for humans to survive, the Atlantic current will have already collapsed, so bug chunks of Western Europe will probably be under a glacier.
- landemva 3y agoUSGS has a decent and short write-up of glaciers across Europe. It says 20,000+ years ago. https://www.usgs.gov/media/images/glaciers-extended-over-much-europe-during-last-ice-age https://www.usgs.gov/media/images/glaciers-extended-over-muc...
- hedora 3y agoYeah; crucially, we have some fossil record of the run up to that glacier, with 50 year resolution: Sample 1: Normal Sample 2: Atmospheric CO2 spike. Sample 3: Glacier Based on that, we are 0-75 years away from the next European ice age, which the maximum expectation estimate at ~25 years.
