Thanks to an unusually warm spring followed by a hot summer, Cleveland and Columbus both had their highest average annual temperatures this past year.
Both cities broke records set in 1998. Columbus had an average temperature of 56 degrees in 2012. Toledo, Cincinnati and Dayton all fell short of breaking their records, but 2012 was among the five hottest years those cities have posted. State climatologist Jeffrey Rogers says more and more evidence points to global climate change for the spiking temperatures. He says the state has seen rising temperatures since the 1960s.
