[font size=3]Washington, DC— Climate change caused by greenhouse gas emissions will alter the way that Americans heat and cool their homes. By the end of this century, the number of days each year that heating and air conditioning are used will decrease in the Northern states, as winters get warmer, and increase in Southern states, as summers get hotter, according to a new study from a high school student, Yana Petri, working with Carnegie’s Ken Caldeira. It is published by Scientific Reports.
“Changes in outdoor temperatures have a substantial impact on energy use inside,” Caldeira explained. “So as the climate changes due to greenhouse gases in the atmosphere, the amount of energy we use to keep our homes comfortable will also change.”
Using results from established climate models, Petri, under Caldeira’s supervision, calculated the changes in the number of days over the last 30 years when U.S. temperatures were low enough to require heating or high enough to require air conditioning in order to achieve a comfort level of 65 degrees Fahrenheit. She also calculated projections for future days when heating or air conditioning would be required to maintain the same comfort level if current trends in greenhouse gas emissions continue unchecked.
Looking forward toward the end of this century, her calculations found that Washington state will have the smallest increase in air conditioning-required days and southern Texas will have the largest increase. Likewise, upper North Dakota, Minnesota, and Maine would have the largest decrease in heating-required days and southern Florida would have the smallest decrease.
