Examples
Yet mankind muddled through the last Ice Age’s death throes and has done rather well since, despite a 100-meter rise in sea levels!

Objections and Replies
Before. We already had similar temperatures in previous times—
☞ At present rates of human emissions, there will be more CO2 in Earth’s atmosphere by 2025 than at any time in at least the last 3.3 million years.
Eemian.
Prosperity. Warmer periods are generally a time of prosperity—
☞ Had we been around during the Neoproterozoic, humans might have needed robust air conditioning.
LIA. The Little Ice Age
☞ We have evidence that the indian genocide contributed to the Little Ice Age.
MWP. They tried to erase the Medieval Warming Period—
☞ The MWP was before 1400, and MBH’s series go 1400 onward. However, note that the bigger the temperature swings in historical times, the bigger should be climate sensitivity.
Notes
Details on all the historical times can’t be covered here. We provide a blueprint for the kind of exchanges to expect. Do your homework!
