The first humans to inhabit what today is known as Ohio were hunter-gatherers who lived at least 13 thousand years ago. More recently, but prior to European colonization, Native American tribes including the Erie, Kickapoo, and Shawnee tribes called the state’s 41 thousand square miles home. Today, over 11.5 million people live in Ohio much of which is covered by the Appalachian Plateau, which boasts terrain more rugged than the low-lying Great Lakes Plains of Ohio’s northern region.

Climate change is threatening Ohio’s water systems. Over 400 thousand people live in areas that are at an elevated risk of flooding. The number of heavy downpours per year has increased steadily since 1950, and rainfall during the four wettest days of the year has increased about 35% in the last 50 years. Warmer waters also affect the water quality of Lake Erie, which 12 million people—and many Ohioans—depend on for drinking water. Algae blooms more readily both in warm water and after severe storms when pollutants increase that run off from land into the lake. It got so bad in 2014, that an algae bloom in Lake Erie prompted the city of Toledo to ban drinking and cooking with tap water

Between 2012 and 2019, Ohio’s natural gas production increased by more than 30 times, almost entirely due to Utica Shale. Ohio continues to rely heavily on coal, and 2019 was the first year that natural gas generated more of Ohio’s in-state electricity than coal even as its natural gas production was down in 2020, which can likely be attributed to the economic crisis prompted by Covid-19 (8). Ohio is one of the top ten coal-consuming states and more than three times as much coal is consumed in Ohio than is produced. Renewable energy accounts for almost 3% of Ohio’s electricity generation, 60% of which is wind energy

In 2008, the Ohio General Assembly established the Renewable Portfolio Standard for Ohio-owned utilities and any competitive electrical seller in the state, mandating that these companies must source 12.5% of their portfolio from renewable resources. A 2019 bill signed by Governor DeWine decreased that standard to 8.5%, an extremely disappointing development for those advocating for a transition to a renewable economy. On the positive side, in September, 2020, Ohio has approved North America’s first freshwater offshore wind project — six wind-turbines to be installed in Lake Erie — clearing a major hurdle. With some details still to be worked out regarding mitigating harm to animals, the farm is scheduled to be operational by 2022

Ohio has not developed a state-wide climate adaptation plan. However, individual cities like Cleveland, Columbus, and Cincinnati all, principally in 2018, have developed their own various climate adaptation plans.
