An analysis done by Climate Central shows that demand for air conditioning in the U.S. will increase by 59% by the year 2050. According to the study, there has been a continued rise in demand for air conditioners in the U.S. and other parts of the world because of global warming. The study shows that continued greenhouse gas emissions are leading to unpredictable weather patterns in most regions. Regions that were traditionally colder are warming up, and those that are warm are getting hotter. These changes are forcing more people to use air conditioners to regulate home temperatures.
The study was based on data collected from 242 U.S. cities. The data tracks down air conditioning usage via a measure known as cooling-degree days (CDD). Cooling-degree days simply refers to the difference between the accepted temperature for human comfort and the daily average temperature. The human body is expected to feel comfortable at 65°F. Any temperature below or above 65°F can lead to discomfort, hence the demand for air conditioning. If a region experiences a daily average temperature of 80°F, the CDD for that location would be 15.

Analysts behind the study have revealed that 96% of the cities in the U.S. have experienced an increase in CDD between 1970 and 2019. Some of the states that have been widely affected by high CDD include Texas, Nevada and Arizona.
Higher temperatures are pushing more people to purchase air conditioners. Today, many people use some form of air conditioning to control the temperatures in their homes and offices. Sean Sublette, a meteorologist at Climate Central, said that the average person uses air conditioning to deal with higher temperatures without thinking about climate change, which is only made worse by increased reliance on air conditioners.
“When our air conditioning is powered by electricity generated through fossil fuels, heat-trapping CO2 is released,” Climate Central explained. “Air conditioners emit heat back outside and can add to the heat island effect in urban areas. And if old air conditioners are not disposed of properly, they can leak chemicals that are themselves harmful heat-trapping gases.”
