Climate Central’s latest report, Warming U.S. Cities Face Higher Cooling Demand and Energy Bills, argues that climate change is driving increased cooling demand and higher electricity costs across America. Climate Central describes “cooling degree days as a temperature-based metric used to estimate the demand for energy to cool buildings.” Climate Central’s own methodology states that it calculated cooling degree day trends using temperature records from 241 urban locations between 1970 and 2025. Climate Central’s attribution of rising household cooling bills to a warming climate is equally flawed. Nevertheless, Climate Central repeatedly presents increasing cooling degree days as evidence that greenhouse gas emissions are responsible for rising cooling demand.
