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.
Dust Bowl. Explain how we could have prevented the Dust Bowl—
☞ Better soil conservation and land management practices might have helped. AGW makes these extreme events more likely. June 2021 was the
Eemian. —
☞
Greenland.
LIA. The Little Ice Age—
☞ We have evidence that the indian genocide contributed to the Little Ice Age.
MBH. Mike’s magnum opus has been discredited by the Auditor—
☞ That paper has been published in 1998, and contrarians are responsible for the Streisand Effect. Besides, seldom is the question asked: is the Auditor audited? Rarely.
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.
Prosperity. Warmer periods are generally a time of prosperity—
☞ Had we been around during the Neoproterozoic, humans might have needed robust air conditioning.
Romans. Still too cold to grow wine in the North of England as the Romans—
☞ The Nene Valley is not the North, and a Scot made wine recently. England has more than 450 wineries and produces around 3.15m bottles a year, where there was a bumper harvest in 2018. Oh, and there’s a vineyard in Norway!
Thermopylae. The battle was on a 100 m strip that is now 1 km, so sea levels—
☞ Incorrect: the depositional process of the Sperchios River has filled a considerable part of the basin with alluvial sediments.
