Climate change will drive an increase in summer air conditioning use in the United States likely to cause prolonged blackouts during peak summer heat if states do not expand capacity or improve efficiency, according to a new study of household-level demand.
Climate change will drive an increase in summer air conditioning use in the United States likely to cause prolonged blackouts during peak summer heat if states do not expand capacity or improve efficiency, according to a new study of household-level demand.
The study projected summertime usage as global temperature rises 1.5 degrees Celsius (2.7 degrees Fahrenheit) or 2.0 degrees Celsius (3.6 degrees Fahrenheit) above preindustrial levels, finding demand in the United States overall could rise 8% at the lower and 13% at the higher threshold. The new study was published in Earth’s Future, AGU’s journal for interdisciplinary research on the past, present and future of our planet and its inhabitants.
Human emissions have put the global climate on a trajectory to exceed 1.5 degrees Celsius of warming by the early 2030s, the IPCC reported in its 2021 assessment. Without significant mitigation, global temperatures will likely exceed the 2.0-degree Celsius threshold by the end of the century.
