The westward migration in America was at least in part caused by the Dalton Minimum.
– Joseph Kraig
Most people have never heard of the Dalton or Maunder Minimums
Ignorance they say is bliss, but it is not. In the early part of the 19th century when the Dalton Minimum was in full swing there were summers that would not support a harvest, with frost in July in Vermont, New Hampshire and New York. The westward migration in America was at least in part caused by the Dalton Minimum when farmers moved southwest to find farms that would support them. They could do this because for many places no one was living there except nomadic Indians. Today there is no place else to go.
Today people take abundance for granted. I do believe that shortages will not come all at once. There is pork shortage in Asia now. The USA is starting to fill some of those shortages which will cause pork prices to go much higher than in recent past. As the disease in North Korea spreads to China and other countries where pork farming is low tech the shortages will only get worse.
I drove through Nebraska and Kansas this summer. I was appalled to find mile after mile of farm fields under water. There will be no corn or soy beans from those fields. Much of Central Canada had a very late spring and early winter, snow on the ground now makes it impossible for crops to mature and impossible for the tractors to harvest crops if they were to mature. There were good harvests in much of the USA that will help compensate for losses but as the Minimum deepens it will get worse. We can handle a bad year now and then but several in a row will be devastating.
Stock up on grains now to prepare for the shortages that are likely to come.
