ItвЂ™s a problem that stretches across the United States, and now, with rising global temperatures, heat is no longer a danger just in places like Phoenix. Ebi, a professor of global health at the University of Washington. вЂњIf 130 homeless people were dying in any other way it would be considered a mass casualty event,вЂќ said Kristie L. Just in the county that includes Phoenix,В at least 130 homeless peopleВ were among the 339 individuals who died from heat-associated causes in 2021. The past few summers have been some of the hottest on record, according to The Associated Press.

Temperatures are rising nearly everywhere because of global warming, and combineВ with brutal drought in some places to create more intense, frequent, and longer heat waves. Around the country, heat contributes to some 1,500 deaths annually, and advocates estimate about half of those people are homeless. High temperatures bring heat-relatedВ weather deathsД®xcessive heat causes more weather-related deaths in the United States than hurricanes, flooding and tornadoes combined. 'The big difference is, compared to last week, much of this heat -В it's not going to be several days in a row,' Roys said. The good news, Roys said, is that the heat in the lower Midwest and nearВ the Ohio River Valley andВ mid-Atlantic won't last as long as last week's heat wave when some cities in the region experienced high temperatures for three or four days straight. Louis andВ Kansas City, MissouriВ could possibly see temperatures in the 100s, Roys said.ДЄs next week goes on,В highs in the 90s areВ likely inВ WashingtonВ andВ Pittsburgh. Meanwhile, stormsВ in the West are going to help push the heat eastward early next week.В As the heat dome inches east, the lower Midwest will also see scorching high temperatures.ДЄround Tuesday, Chicago, St. 'The ground is already dry, so there's no moisture in there at all, so that air is able to rise faster,' Roys said. Prolonged, severe drought in much of the southwest has been feeding the heat dome even more than normalВ becauseВ drought-stricken ground bakes even fasterВ under the hot sun. Roys said weather patterns slow down when there's high pressure, so the heat dome isВ 'kind of likeВ a roadblock,' forcing storms to go around it. High atmospheric pressure from aВ 'heat dome' has been causing rising temperatures to stick around, while preventing storms from bringing cooling rain. Why is the extreme heat happening before start of summer?
