There is one group, however, that is slightly less anxious than the rest of us about this news: a small number of young professionals who are preparing homes away from the places where climate change is expected to strike the hardest. They are following in the footsteps of billionaires like Peter Thiel, who is investing in real estate in New Zealand in case a climate apocalypse occurs. Although they are doing it on a far more affordable scale.

They have studied maps and research that show the areas of the country that will be less affected by devastation, either because of geography or an ample supply of natural resources. And they are optimistically buying land and homes in these areas, many of them mentioned in an article published in Popular Science in December 2016 titled “These will be the best places to live in America in 2100 A.D.,” which has amassed 28,000 views in the past six months and gets about 100 Google search hits a day.

Not quite survivalists, they are nonetheless teaching themselves essential life skills — like how to grow their own food and make their own electricity — just in case things spin out of control, and the government can’t step in to help. They believe they are making sound real estate decisions by buying land on high ground that will appreciate in value, while at the same time developing a Plan B.

“We are blatantly facing a catastrophe, and all we’re doing is getting rid of straws,” Mr. Dalski said. “There are things I’m going to do for preservation.”

That includes buying land on a wooded, undeveloped part of Plattekill, a 3,500-foot mountain in the Catskills, because the area is filled with natural resources. The land is at a high elevation but it is also in a bowl, so it collects precipitation. Also, there are creeks that run through the area year-round, and he has family nearby.

Michael Phelan, 26, a Ph.D. student in bioengineering in Philadelphia, is deeply concerned about life in a post-climate change world as well.

“I’ve been hearing people talk about moving north to places like Michigan or Maine,” he said. “Seeing how recent government reports have detailed the threats of mass migration or economic loss, I wonder if it’s even possible to move away from it.”
