The American tropics

The New York Times provides a visualization of the steady Northern march of extreme heat due to global warming. By 2060, much of the country will experience 20+ days a year above 100ยบ F.

By the end of the century, that will expand to include almost the entire country except for Northern coastal areas, the West coast and the high Rockies.

It's easy to see this as a map of where not to live. It must also be a call to action. Unfortunately, it feels like we are slipping past the point of no return. The feedback cycles are already in motion. Even with massive cuts in carbon emissions, radical geoengineering may be our only option to preserve the climate our species has prospered in for the last 50,000 years.
