Yeah; 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

Yeah; 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.
