Climate & the U.S. Flood Insurance Program

The U.S. Federal Emergency Management Agency has released an assessment of the effects of future climate change and population growth on the U.S. National Flood Insurance Program (NFIP). The study concludes that floodplain area in the United States is projected to grow by 45% (median estimate) by 2100. Approximately 30% of this increase is due to increased flood discharge due to increasing population density while the other 70% is due to climate change. This increase in floodplain area is projected to translate into an 80% increase in NFIP policies, a 50% increase in losses per policy, and a 40% increase (current dollars) in NFIP premiums.
