Key Findings 2015

For over a century weather events have become more extreme, turning normal fluctuations into long-term climate trends. Today, heavy rains increasingly pound northeastern states, the southwest is in a long term drying pattern, the western wildfire season is 60 days longer, rising seas compound damaging coastal storms, and the Southeast and Gulf Coast states are on the verge of exceeding critical heat thresholds that seriously endanger human health. 

Extreme heat, drought, wildfiresinland flooding and coastal flooding threaten different regions of the U.S. in different ways, but all are increasing. Regardless of what we do to slow the warming that fuels these changes, massive global forces have been set in motion that will perpetuate these trends for many decades.

States need to prepare now for the inevitable increases in severe weather that a warming world will bring. Extreme weather events will be even more extreme in the future and preparedness plans that fail to take this into account will fall short, perhaps tragically so.

States at Risk: America’s Preparedness Report Card is the first-ever national analysis of state level preparedness for climate change-driven, weather-related threats facing all 50 states. For more information on how we prepared the Report Card, read our About page and our methodology

The Threats

Across the country, extreme heat, drought, wildfires, inland and coastal flooding aggravated by sea level rise pose a significant and increasing risk to people and the economy. With a few exceptions, states are reasonably well prepared for current threats, but very few have taken actions sufficient to prepare for the increasing risks of the future.


Extreme Heat 

Extreme heat is the most pervasive threat, affecting every state, particularly in the Southeast and along the Gulf Coast where the combination of heat and humidity is projected to cross thresholds dangerous for human health within the next decade. By 2050:

  • 11 states are projected to have an additional 50 or more heat wave days per year
  • 2 states will have an additional 60 or more heat wave days per year
  • Florida is projected to have 80 heat wave days each year

Extreme heat is the threat where states are least prepared; only seven states have taken strong action to prepare for extreme heat risks.


Summer Drought

Texas currently faces the highest overall summer drought threat of any state, by a substantial margin. By 2050, however, nine states; Colorado, Idaho, Montana, New Mexico, Texas, Michigan, Wisconsin, Minnesota, and Washington are projected to face a greater summer drought threat than Texas does today. Some, like Colorado, Washington and Michigan are reasonably well prepared overall, earning a B or higher.  Others, like Texas and Montana have taken little action, scoring a D- and an F respectively.



The growing threat from wildfires is concentrated in four states, Texas, California, Arizona, and Nevada, where more than 35 million people live in the high threat zone where wildlands and development converge. But climate-driven wildfire threats are not restricted to western states.

  • Florida, North Carolina and Georgia combine for another 15 million people at risk
  • a group of Southeastern states; Arkansas, Alabama, Louisiana, and Mississippi all face above average increases in wildfire risks by 2050

Current preparedness for wildfires is very high, but readiness for future climate-driven wildfire threats is very low; 15 of the 24 states analyzed do not have a climate adaptation plan that includes wildfires.


Inland Flooding

Florida and California have the largest populations vulnerable to inland flooding, with 1.5 million, and 1.3 million, people living in the inland FEMA floodplain, respectively. Georgia is third most at risk with 570,000 people. More than half of all states assessed (17 out of 32) have taken no action to plan for future climate-related inland flooding risks or implemented strategies to address them.


Coastal Flooding

Florida and Louisiana face enormous coastal flooding threats, far greater than any of the other 22 coastal states. Florida alone has 4.6 million people projected at risk (living in the 100-year coastal floodplain) by 2050. Louisiana has 1.2 million. Overall, states are more prepared for coastal flooding than for any other threat. Florida, however, is not among them. Florida earned an F for coastal flood preparedness, due to its average level of readiness in the face of enormous current and future risks. Louisiana, which is far better prepared, earned a B-.
