At least 75 record-breaking extreme weather events occurred in Ohio during 2012.
Nationally, 3,527 monthly weather records for heat, rain and snow were broken by extreme weather events, according to an updated review released by the Natural Resources Defense Council, an environmental group.
The figures reveal an increase over the 3,251 weather records smashed in 2011.
Among the record-breaking events in Ohio, the Buckeye State had:
* Record-breaking heat in 26 counties, with a total of 55 new heat records
* Record-breaking rainfall in nine counties, with a total of 10 new rainfall records
* Record-breaking snow in nine counties, with a total of 10 new snow records
* 1 large wildfire
"2012's unparalleled record-setting heat demonstrates what climate change looks like," said Kim Knowlton, the NRDC's senior scientist.
"This extreme weather has awoken communities across the country to the need for preparedness and protection," Knowlton added. "We know how to reduce local risks, improve our lives and create more resilient communities. Now our leaders must act."
The monthly weather records are compared against prior records set during the last 30 years at each location.
In 2012, Americans experienced the hottest March on record in the contiguous U.S., and July was the hottest single month ever recorded in the lower 48 states.
As a whole, 2012 was the warmest year ever recorded in the U.S., according to the National Oceanic and Atmospheric Administration.
Summer 2012 had the worst drought in 50 years across the nation's mid-sectiont, with more than 1,300 U.S. counties in 29 states declared drought disaster areas.
Further, Hurricane Sandy's storm surge height -- 13.88 feet -- broke the all-time record in New York Harbor.
Groups like the Natural Resources Defense Council say the extreme weather events are caused by human activity, and want governments to reduce carbon emissions.
Some conservatives, however, counter that the events are due to natural fluctuations in the planet's weather cycle that occur over long periods of time.
