The ignorance of this comment is breathtaking. How are the crops going to grow if the temperature drops by 15 degrees Celsius? What marine and terrestrial ecosystems can survive a sudden catastrophic change like that? What’s going to happen to the weather patterns after this planet-scale shift? How do you “adjust” to the collapse of your food supply and entire ecosystems?

Grow the crops somewhere else? The earth's climate has always changed - the sea was 100m lower 20k years ago and much of Europe covered by ice. But it doesn't change so much over one human lifetime.

20k years ago, humans hadn't invented agriculture. Our whole civilization has existed in one particular geological time, an exceptional one. There is absolutely no indication that it's flexible enough to be transposed in another, and particularly not at that speed of transition, which is, in geological time, exceptionally fast.

We've gotten this far because we've had a rather stable climate for the past few thousand years. The current rate of the change is the problem.
