Middle class Americans are moving straight into fire and drought because they can't afford to live in the cities that are safer from climate change

• Rising housing costs have helped push Americans into parts of the country more vulnerable to climate change. 
• US counties that have the most at-risk homes are all growing in population.
• The trend shows how the burden of climate change is falling disproportionately on less affluent people.

The skyrocketing cost of housing has pushed many Americans to trade their lives in big coastal cities like New York and San Francisco for more affordable ones in Sunbelt cities and Southern suburbs. 

But that move could cost more in the long-run.
