In areas such as the Great Plains and the Midwest, temperatures are expected to be 10 to 15 degrees above average, with heat waves expected to spread to much of the continental United States next week, according to the National Weather Service.
Expected heat and high humidity occur shortly after a record heat wave brought triple-digit temperatures to Oregon, Washington, and British Columbia at the end of June, causing hundreds of heat-related deaths.
Next week’s temperatures will result in a heat dome, a powerful high-pressure air system that descends from the atmosphere, compresses and heats near land, and exacerbates already hot summer temperatures.
Heat domes tend to impede cloud formation, leading to hot, sunny skies that are not covered by clouds, which can become even more severe as the climate changes.
Researchers have found that the June heat wave, also a result of the heat dome, was estimated to be a once-in-a-millennium event that would have been virtually impossible without anthropogenic climate change.
Temperatures and drought conditions also caused more severe wildfires this year, which ignited earlier than usual. More than 80 wildfires have recently occurred in more than 12 states, especially in the western part of the country, which has been hit by unprecedented droughts.
The smoke from the western fires is so terrible that this week it created a hazy sky and unhealthy air quality in New York, New Jersey and Pennsylvania.
According to the World Meteorological Organization, the Earth is already hotter than 1 degree Celsius compared to pre-industrial levels. Last year was the hottest on record, and 2021 is virtually certain to be among the hottest decades ever recorded.
Studies show that more than one-third of the world’s heat-related deaths in warmer months are due to climate change.And heat kills more people than any other weather disaster in the United States
Hot and humid temperatures expected throughout the United States due to the heat dome
