Climate Change Risk Ratings for Ohio

People in Ohio will experience especially increased risks from precipitation, heat, and flood due to climate change over the next 30 years. These risks, through 2050 and beyond, may change depending on how much we reduce emissions in the near future.

ClimateCheck Risk Ratings measure the risk posed by a hazard on a 1-100 scale, using historical conditions and projected scenarios through 2050. Climate change has complex, interacting local and large-scale effects that impact everyone on Earth, and a low risk rating does not mean no exposure to impacts from that hazard. See how we measure risk.

Ohio Rankings for Climate Change Risk

Precipitation Risk in Ohio with Climate Change

To measure precipitation risk, we look at the amount of precipitation that falls in 48-hour periods exceeding a location-specific threshold, and how many times this happens per year. A precipitation threshold is based on the top 1% of rainiest days per year for a location.

Historically, Cincinnati experienced an average of 1.4 inches of rain about 11 times per year. In 2050, it is projected to experience an average of 1.3 inches of rain about 13 times per year.

Historically, Canton experienced an average of 1.2 inches of rain about 11 times per year. In 2050, it is projected to experience an average of 1.1 inches of rain about 14 times per year.

Drought Risk in Ohio with Climate Change

Drought risk is based on water stress, which is a projection of how much of the water supply will be taken up by human demand.

In the figure, the blue bars represent the available water every 10 years from 2020-2060, and the orange bars represent demand. The drought risk rating is based on the ratio of supply to demand and the projected change in this ratio. Lower supply and higher demand correspond to a higher score.

How can we prevent climate change and protect our homes and communities?

Mitigating climate change—by eliminating our emissions into the atmosphere and reducing our strain on the environment—and adapting to our changing planet are both vital to our well-being.

Understand Risks

Your level of risk depends on your city's capacity to adapt. Look up information on your city's characteristics and how they relate to preparedness for climate change: ND-GAIN Urban Adaptation Assessment.

Protect Homes and Communities

Check our free report for tips on protecting your home from hazards.

Green infrastructure is a category of nature-based solutions to increasing precipitation. Find resources for individuals and municipalities through the EPA's Soak Up the Rain initiative.

Planting trees and vegetation helps reduce extreme heat in urban environments. Cool Pavements can also help urban heat islands. Search the Heat Island Community Actions Database to see what some municipalities have been doing to reduce extreme heat risk.
