djf~:” Something happened about 75,000 years ago. And except for the very central tropics, worldwide temps fell by 10 degrees Celsius for almost a thousand years!”
If my calculations are correct , I believe that the reported “ 10 degrees Celsius” for 1,000 years would compute to a 50 º temperature change in Fahrenheit.
If that would be occurring for 1,000 years , that would represent a short ‘ ice age’ , I believe .
I would call it that. But I think the data they rely on for long-term climatology is not fine enough to show it. The Vostok data shows a major glacial maximum about 115,000 yrs ago, I’m not sure of Toba shows up.
F= C*1.8 + 32
10°C equals a total of 50°F
DF = DC * 1.8
A change of 10°C equals a change of 18°F
