The National Climate Assessment, a stunning report released by 13 federal agencies and the White House this month, showed that climate change has already had devastating impacts on our health and economy, and that costs could mount to hundreds of billions of dollars by the end of the century.

The report maps out what we can expect if we aggressively cut greenhouse gas emissions now, and what would happen if we do nothing. As part of our Weather 2050 project, we used the latter scenario to look at what could happen to temperature and precipitation in US cities by the middle of the century.

We found that by 2050, many US cities may resemble hotter, more southern parts of the country today. We’ve mapped a few of the most striking transitions here:

As you can see in this map, climate change means cities could move further south in terms of their temperature and rainfall patterns. In some cases, the closest match may be hundreds of miles away. If you want to get a sense of […]
