Annoying Lead Time Graph | Musings from the Chiefio

All in all, this graph tells me that we are on the knife edge of a drop into a cold stage and acceleration into a glacial stage, from which we can not recover....
So if we are very lucky, and do not have a major volcanic event, nor have a nuclear winter, nor have a rock fall from space in size, nor any other cooling event that causes multi-year ice to start collecting near the north pole, we can maybe stay warm. But if an ‘aw shit’ happens, we fall into a non-recoverable decent into the next glacial. We can only exit a glacial when there is sufficient energy to prevent multiyear ice from accumulating at the North Pole. We are presently out of that realm for a large ice pack. Essentially, once the Arctic freezes and does not melt for a few years, we’re done.

It looks like, during a very cold glacial, CO2 levels plunge to plant starvation levels and plants don’t grow as well…

So once it gets very cold, and the cold rain / arctic snow CO2 scrubbers kick in, the food production gets cut too. Along with the fire wood.
