America's Preparedness Report Card 2015

View Map

Oklahoma faces growing threat levels from extreme heat, drought, wildfire, and inland flooding between now and 2050. The state has taken strong action to address current risks, but besides some efforts around projected future drought risks, it has taken almost no action to prepare for its climate change-related risks. Oklahoma will need to do more to plan for climate change and implement adaptation measures if it hopes to be prepared for future risks.

Extreme Heat

Oklahoma already faces a high level of threat from extreme heat, but the state has taken strong action to address related risks. Although its increase in threat level by 2050 is projected to be modest, Oklahoma lags behind other states in preparing for future heat risks: it has taken little action to plan or implement adaptation strategies.


Oklahoma is better prepared for its projected future drought risks than most other states; it has a climate-change adaptation plan in place, albeit only for the water sector. On the other hand, Oklahoma has done less than most states to address its current drought threat.


Oklahoma faces a moderate threat level from wildfire, and like most states it has taken strong action to address its current risks. But Oklahoma needs to do more to improve its preparedness for its projected future wildfire threat, especially by, for example, conducting a climate change vulnerability assessment and developing an adaptation plan.

Inland Flooding

Oklahoma faces a moderate threat from inland flooding compared to other states assessed, but its efforts to address that threat fall behind that of most other states. While Oklahoma, has taken strong action to address its current risks from inland flooding, it has taken no action to plan for climate change-related inland flooding risks, or to implement adaptation strategies.

Coastal Flooding

Grades were assigned only when threats were identified as priorities for that state. For details, see the methodology.
