Heat Dome Expands Across Central US, Creating Dangerous Conditions Dangerously hot weather is spreading across much of the central United States, with temperatures expected to exceed 100 degrees Fahrenheit (37.8 degrees Celsius) from Dallas to North Dakota. Roughly 70 million people are under heat advisories as a persistent heat dome traps warm air, creating sustained high temperatures and uncomfortable conditions. Forecasters warn that overnight low temperatures will not drop sufficiently for people to recover, allowing heat stress to build as the weather lingers. High humidity will exacerbate the situation, making the heat feel even more intense. The heat dome is expected to stretch from the desert Southwest to the Gulf Coast, reaching into the Midwest and Great Plains. Some records in the Denver area may be broken, with temperatures projected to be 10 to 15 degrees Fahrenheit (5.6 to 8.3 degrees Celsius) above normal. Meteorologist Bob Oravec of the National Weather Service noted that the heat dome is likely to remain stationary in its position throughout the week, intensifying the conditions. Extreme heat warnings have been issued for western Nebraska, where temperatures are forecast to reach 108 degrees Fahrenheit (42 degrees Celsius) on Saturday and Sunday. In Chadron, Nebraska, the Museum of the Fur Trade reported fewer visitors than usual for this time of year, and the gift shop’s fur hats and pelts saw little sales. The heat is expected to continue through the week, with temperatures surpassing 100 degrees Fahrenheit even in typically moderate areas of Montana and Wyoming. While some relief may arrive in the central United States by next weekend, Oravec cautioned that this might be temporary.#national_weather_service #denver #associated_press #heat_dome #chadron_nebraska
Scorching US heatwave to hit 70 million people with third ‘heat dome’ in month A third major heat dome event is set to blanket the United States, affecting approximately 70 million people across southern and central regions. Temperatures are expected to soar between 95 and 105 degrees Fahrenheit (35 to 40 degrees Celsius), with some areas in the southwestern desert potentially reaching 120 degrees Fahrenheit (48 degrees Celsius). The heat dome, a high-pressure atmospheric system that traps warmth over a region for days or weeks, is expected to persist into the following week, creating a prolonged period of extreme conditions. The current heatwave follows two previous heat dome events in the same month, marking an alarming trend of increasing frequency and intensity of such weather patterns. The National Weather Service has issued extreme heat warnings for western Nebraska, where weekend temperatures are projected to hit 108 degrees Fahrenheit (42 degrees Celsius). The Denver area could potentially break temperature records during this event, further highlighting the severity of the situation. Heatwaves have long been a feature of American summers, but their regularity and intensity are worsening due to human-driven climate change. The accumulation of heat-trapping gases from fossil fuel combustion has pushed global temperatures beyond historical norms, exacerbating the impact of these events. This summer has already seen record-breaking heat, with a massive heat dome in early July leading to the cancellation of Independence Day celebrations in the eastern U.S. A subsequent heatwave in the western states caused temperatures to reach 115 degrees Fahrenheit (46 degrees Celsius) in Montana, shattering temperature records.#united_states #national_weather_service #denver #climate_central #heat_dome
Why Temperature Records Are Being Not Only Broken But Smashed Across western Europe, temperatures have surged to unprecedented levels, with the UK experiencing its hottest May day on two consecutive days. On Tuesday, the country recorded temperatures exceeding 35°C, surpassing the previous May record by more than 2°C. The Met Office described this heat as "exceptional," even for summer conditions, and emphasized its rarity in spring. Similarly, France is grappling with an early-season heatwave, with hundreds of temperature records shattered. The island of Ireland also saw its May temperature record broken by over 2°C, while Germany, Italy, Spain, and Switzerland faced unusually hot conditions for this time of year. The immediate cause of this extreme heat is a "heat dome" — a high-pressure system that traps warm air over an area, creating prolonged periods of intense heat. However, scientists attribute the severity of the event to human-driven climate change. The burning of fossil fuels has accelerated global warming, making heatwaves more intense and frequent. Over the past 30 years, Europe has warmed by 0.56°C per decade, more than double the global average. This rapid warming has intensified heat extremes, with experts noting that even a weather event from the 1970s would now "smash" records due to the warmer baseline. The phenomenon of record-breaking temperatures is not limited to Europe. In India, temperatures in Delhi reached 45°C, highlighting the global scale of the issue. Climate scientists like Erich Fischer of ETH Zurich explained that in a stable climate, records should become rarer over time. However, in a rapidly warming world, the margin between record-breaking events can be vast.#imperial_college_london #heat_dome #climate_change_committee #erich_fischer #richard_betts
