Conversely, Canada is not expected to be a great beneficiary of climate change (except for the Northwest Passage becoming passable), because most of what is not currently used isn't because of temperature, but because it is muskeg.
From David Wallace-Wells's "The Uninhabitable Earth":
In 1879 the naturalist John Wesley Powell [..] divined a natural boundary running due North along the 100th meridian. It separated the humid—and therefore cultivatable—natural farmland of what became the Midwest from the arid, spectacular, but less farmable land of the true West. The divide ran through Texas, Oklahoma, Kansas, Nebraska, and the Dakotas, and stretches north into Manitoba, Canada, separating more densely populated communities full of large farms from sparser, open land that was never truly made valuable by agriculture. Since just 1980 that boundary has moved fully 140 miles east, almost to the 98th parallel, drying up hundreds of thousands of square miles of farmland in the process.
Maybe it won't turn into desert exactly but it won't be productive for growing food.
There are expected to be agricultural impacts:
> The Midwest is a major producer of a wide range of food and animal feed for national consumption and international trade. Increases in warm-season absolute humidity and precipitation have eroded soils, created favorable conditions for pests and pathogens, and degraded the quality of stored grain. Projected changes in precipitation, coupled with rising extreme temperatures before mid-century, will reduce Midwest agricultural productivity to levels of the 1980s without major technological advances.
I know you're responding to a comment talking about climate refugees ... the HN comments often jump quickly from realistic scenarios to Mad Max.
But even the projected impacts are significant. Other concerns are impacts to the Great Lakes and to extreme heat events. All covered in the link, which is really very good.
I don't know if you live there or keep in touch with people there. The changes in snow and rain patterns since my childhood in the 70s/80s seem noticeable to me -- although I'm open to correction since I haven't looked at the numbers and this kind of change is not covered in the above report. I don't remember rain in February in Kansas, for instance, but it happens now.
I realize that Global Warming != Warming Winters because climate is more complex than that, and odd weather has always been a staple of Michigan on account of the Great Lakes, but this just felt unprecedented, and a bit concerning if it continues in this direction.

By contrast, practically all of Florida would be gone with that rise.
