The fall crop is in, harvested. But the map of what we grow, where, is changing, with climate change. We’ll look at the new map of North American food production.
Look at a crop map of North America over the years and you’ll see there is a great migration going on in food production. Crops heading north. Corn and beans – soybeans – marching north toward the Canadian border and spilling over it into brand new territory. It’s about plant genetics and farming technique. It’s also about climate change. A southern tier turning too hot and dry. A northern planting season getting longer, more welcoming. Crop production moving. How far can it, will it go? Up next On Point: the new map of North American food production, pushing north with climate change.

From Tom's Reading List
USA Today: Some crops migrate north with warmer temperatures — "North Dakota is at the leading edge of a shift in North American weather patterns, with more variable weather and rainfall; longer, hotter summers; and warmer winters. USA TODAY visited the state as the seventh stop in its look at how climate change is impacting the way Americans work, live and play. In the town of Rugby, N.D., 50 miles south of the Canadian border, climate change is written in the fields. Where once wheat was king, field after field is now full of feed corn. At the beginning of September, farmers are hustling to get combines out to cut the golden wheat but green fields of corn are everywhere — and still a month from harvest."
New York Times: A Jolt to Complacency on Food Supply -- "This may be the greatest single fear about global warming: that climate change could so destabilize the world’s food system as to lead to rising hunger or even mass starvation. Two weeks ago, a leaked draft of a report by the United Nations climate committee, known as the Intergovernmental Panel on Climate Change, suggested that the group’s concerns have grown, and that the report, scheduled for release in March in Yokohama, Japan, is likely to contain a sharp warning about risks to the food supply."
Mother Jones: Climate Change Is Already Shrinking Crop Yields — "Of course, we can't tie any individual heat wave to long-term climate trends—there's plenty of random weather variation even in times of climate stability. But we do know that hot, dry weather can stunt plant growth and reduce yields—and we also know that we can expect more hot, dry weather in key growing regions as the climate warms up."
