The Federal Emergency Management Agency just released a map of estimated flood zones in the United States for the year 2100—and it doesn’t look good. According to FEMA, we can expect a 45 percent increase in the area of the U.S. that will be at risk of major flooding – including almost half of the eastern part of the country, and much of the west. The agency also estimates that 11.2 million homes will be subject to the National Flood Insurance Program as “special flood hazard zones” almost double.

The influx of water across the country is largely attributed to climate change, with FEMA placing 70% of the blame on climate change and global warming issues. The projected maps highlight the Great Lakes region to be the hardest hit area for river-related flooding, while the Northwest, Gulf of Mexico and Atlantic Coasts are the more obvious, large body-related affected zones.

The pink and red map that FEMA has released shows only a small snippet near Montana and Wyoming that seem to go unharmed, with even small chances of flooding in interior states with higher elevations.

Aside from the total catastrophe of flooding and flood damage, the FEMA report also looks into just who will pay for future damage caused by impending storms. The National Flood Insurance Program will have to double its covered housing, from 5.5 million to 11.2 million, which will also drive up insurance premiums by 50-90%. Where this money will come from remains to be seen, but FEMA’s report shows that the government is considering the long term outcomes of climate change.
