That system sends air sinking, pressure increasing and temperatures rising.<\/p>\n<p>\u201cThe concept of a heat dome really means that the air in this region is so warm, and we know that warm air expands,\u201d said Jennifer Francis, a climate scientist at the Woodwell Climate Research Center. \u201cIt basically means that the layers of the atmosphere are bulging upward as well.\u201d<\/p>\n<p>Simply put, heat domes cause heat waves. They\u2019re associated with very dry, sunny conditions that last for multiple days at a time, trap heat at the surface and help to amplify it, said Zachary Labe, climate scientist at Climate Central, an independent collective of scientists.<\/p>\n<div>\n<div><\/div>\n<\/div>\n<h4>How has heat affected the world this year?<\/h4>\n<p>Heat impacted various regions of the world\u00a0early in 2026.<\/p>\n<p>The\u00a0continental United States registered\u00a0its most abnormally hot month in 132 years of records in March, with\u00a0record-shattering extremes\u00a0first in the Southwest and then\u00a0across the rest of the nation. Heat\u00a0scorched the French Open\u00a0and\u00a0scorched parts of India\u00a0in May. Extreme heat has since\u00a0been top of mind for the World Cup\u00a0across the U.S., Canada and Mexico.<\/p>\n<div>\n<div>\n<div><\/div>\n<\/div>\n<\/div>\n<p>Starting mid-June, Europe has baked under unseasonable highs of around\u00a040 degrees Celsius\u00a0(104 Fahrenheit) in many places due to a heat dome.<\/p>\n<div>\n<div><\/div>\n<\/div>\n<p>Now, much of the\u00a0Eastern U.S. is expected to be slammed\u00a0by a long heat wave in the coming days, and already, much of the Southwest is experiencing temperatures around 100 degrees Fahrenheit (38 Celsius) this week and those temperatures could reach elsewhere by the Fourth of July holiday.<\/p>\n<p>Read more <a href=\"https:\/\/crosscountrymovingteams.com\/?p=2557\">Warren Buffett breaks from a \u2018lifetime\u2019 pledge to the Gates Foundation as the Epstein fallout deepens<\/a><\/p>\n<div>\n<div><\/div>\n<\/div>\n<h4>What role does climate change play?<\/h4>\n<p>Science shows that as the planet warms \u2014 the result of humans burning coal, oil and gas \u2014 heat waves get worse, last longer and become more frequent.<\/p>\n<p>\u201cHeat waves like this are so directly connected to the climate crisis and climate change,\u201d Francis said, \u201cand it\u2019s because of how we\u2019ve been burning fossil fuels and cutting down forests for so long and increasing the concentration of heat-trapping gasses in the atmosphere.<\/p>\n<p>\u201cThese kinds of heat waves and droughts and associated fires are all increasing just as we would expect them to in a warming world,\u201d she said.<\/p>\n<h4>How can I stay safe?<\/h4>\n<p>Experts say people need to stay hydrated when sweltering heat and humidity hit.<\/p>\n<div>\n<div>\n<div><\/div>\n<\/div>\n<\/div>\n<p>Be sure to avoid outdoor exercise in the heat of the day \u2014 and find shade, or if you can, access to air conditioning. Some cities offer resources and cooling centers to provide relief.<\/p>\n<p>Cooling off in nearby pools or bodies of water can also help.<\/p>\n<p>Heat domes can make it difficult to fully recover from high temperatures at night, so finding ways to stay cool during the day and evening hours are important.<\/p>\n<p>\u201cIt\u2019s those night times \u2014 especially, locations and people, who don\u2019t have access to adequate cooling, really need to be aware of the impacts that added heat stress will have and their body\u2019s ability not to be able to cool down,\u201d Labe said, \u201cbecause humidity is going to be a really key factor in boosting those heat impacts.\u201d<\/p>\n<div>\n<div><\/div>\n<\/div>\n<p>___<\/p>\n<p>The Associated Press\u2019 climate and environmental coverage receives financial support from multiple private foundations.
