Intro:

According to new data from the Rhodium Group analyzed by ProPublica and The New York Times Magazine, warming temperatures and changing rainfall will drive agriculture and temperate climates northward, while sea level rise will consume coastlines and dangerous levels of humidity will swamp the Mississippi River valley.

Taken with other recent research showing that the most habitable climate in North America will shift northward and the incidence of large fires will increase across the country, this suggests that the climate crisis will profoundly interrupt the way we live and farm in the United States. See how the North American places where humans have lived for thousands of years will shift and what changes are in store for your county.

Heat alone, however, won’t determine Americans’ fate. A new climate analysis — presented for the first time here — projects how humidity and heat will collide to form “wet bulb” temperatures that will disrupt the norms of daily existence.

Today, the combination of truly dangerous heat and humidity is rare. But by 2050, parts of the Midwest and Louisiana could see conditions that make it difficult for the human body to cool itself for nearly one out of every 20 days in the year. New projections for farm productivity also suggest that growing food will become difficult across large parts of the country, including the heart of the High Plains’ $35 billion agriculture industry. All the while, sea level rise will transform the coasts.

Combined, these factors will lead to profound economic losses — and possibly mass migration of Americans away from distress in much of the southern and coastal regions of the country. Meanwhile, the northern Midwest and Great Plains will benefit, in farm productivity, in economy and in overall comfort.
