The simple facts are, that all of Canada and half of the USA was once covered in glaciation, and that global warming has receded these glaciers, which has exposed the entire grain belt for cultivation. So no global warming, and we all starve.

So no global warming, and we all starve. You don't even need to go back that far. There are those that believe that if we drop the mean annual temperature of Canada and the Northern plains by 4-6 degrees C, then it basically stops producing most of the grains we grow today. And other areas further south may need to change what they grow. I'm no expert, but that's what they say ... would be somewhat disconcerting for lots of people.

I don't think it stops there....where I live there are substantial gravel deposits, they mark the leading edge of the previous ice ages glacial advance. I'm in North Buckinghamshire, surrounded by prime agricultural land which is what, a 700-1000 miles wide band at this latitude which includes north Europe and Russia and North America. This band of viable climatic conditions for effective production in the event of a significant temp drop simply moves south, away from the machinery, expertise, infrastructure. A logistical horror story.

A logistical horror story. Excellent point, the edge where the glaciers stopped, is not the point where viable cropland begins, as there is likely next to no logical growing season at this place. You might need to travel hundreds of miles to be out of the glacial influence zone, which puts a person at least in what is now the subtropics, and perhaps nearer the tropics. So this global warming, which is the same global warming that is happening now, has allowed for both cultivation of farmland, and for the spread of human culture through the World.

This band of viable climatic conditions for effective production in the event of a significant temp drop simply moves south, away from the machinery, expertise, infrastructure. A logistical horror story. And away from the highly productive, loess-covered, glacial till soils ... the most productive in N. America. It is not that soils further south will not produce anything. It is that world populations have expanded to the point that we require the extensive production of our mechanized agricultural system to feed them ... and soil regions further south our poorly suited to that. If we were a society of intensive Asian farmers with a different standard of living, we could probably feed a lot more people per unit of land. Look at China. But we're not and we probably won't.

Actually, at the end of SC23 (and after several months of no sunspots), in Oklahoma we had cool long late winters and cold springs with rain seemingly almost every day for many weeks. The wheat crops were severely damaged and much of it turned to translucent mush. Prices for all grains spiked.
As far south as Oklahoma and Kansas, cooler and wetter and longer winters did this. That might just be a small taste of whats coming when the sun goes mostly dormant after SC24.

Change of standard of living it'll be then! I'm keeping my rice bowl and chopsticks handy. Just in case.

Next thing, he will be blaming the greying of his hair on carbon dioxide, not hydrogen peroxide !!!

Sig. Do you have any references to CO2 levels and grain production?
