Heatwaves have killed more individuals on common than some other excessive climate event within the US, based on the Centers for Disease Control (CDC).
Officers outline excessive heat as an interval of two to three days of excessive heat and humidity with temperatures above 90F (32C).
On the heels of earth’s hottest June on the report, the US National Weather Service (NWS) estimates over 100 record-high minimum temperatures may very well be set as the heat lingers even past sunset.
Air-conditioning is used in 87% of US homes, in line with a 2018 report by the US Energy Information Administration (EIA). Throughout heat waves, air conditioning use stresses power grids and may result in city-wide outages.
In cities, which means hundreds of thousands of items – including these on cars and buses and trains – always pushing out heat into the atmosphere. Research have discovered the additional heat from air-conditioning can increase temperatures by as a lot as 2C. And when it gets hotter, our thermostats turn lower, and the cycle continues.
However, it goes further than just an ever-hotter summer season – the emissions from air conditioners and their refrigerants is contributing to climate change. The man-made greenhouse gases used in air conditioners, known as hydrofluorocarbons (HFCs), are 1000’s of times stronger than carbon dioxide in the atmosphere.
In cities, the cycle can be exacerbated by all the concrete, asphalt, steel and glass, creating a city heat island.
