While I was reading this USDA report on Climate Change, I was watching the Weather Channel in the background and the National Weather Service was issuing frost and freeze warnings for the mid west.
NORTHERLY WINDS WILL CONTINUE TO PULL COLD CANADIAN AIR INTO THE
GREAT LAKES REGION TODAY. CLEARING SKIES AND DIMINISHING WINDS
WILL ALLOW TEMPERATURES TO QUICKLY FALL TONIGHT...WITH OVERNIGHT
LOW TEMPERATURES AT OR BELOW FREEZING IN MANY AREAS.
The blue is for freezing and the gray for frost.
The USDA report finds that climate change is already affecting U.S. water resources, agriculture, land resources, and biodiversity, and will continue to do so. A complete list of the specific findings can be found here. But, this was the finding I found most interesting, given the above warnings.
• The growing season has increased by 10 to 14 days over the last 19 years across the temperate latitudes. Species' distributions have also shifted.
During the last 19 years during ,the last third of Pacific warm phase PDO, the growing season increased and food production was up as more land at higher latitudes could be put into production. Now with the Pacific in a cool phase PDO we can expect the the growing season to be shortened by 10 to 14 days, reducing food production.
If we were to enter a mini ice age the growing season could be shortened by an additional 10 to 14 days, that could add up to a whole month shorter, reducing food production even more in Northern Hemisphere grain producing regions.
Now I ask you, which would you rather have modest warming and more food, or modest cooling and less food. Or, sever cooling and food shortages across the nation and around the world as grain production declines in American and Canadian bread basket regions? If we have some killing frost in June, you best buy an extra loaf, or two, and put them in the freezer. You will be glad you did.
