About 70 million people in the U.S. are facing excessive heat advisories as dangerously hot temperatures scorch much of the country’s southern and central states, as seen in a trending post on r/news. The third major "heat dome" event in a month is intensifying over the weekend, affecting areas from the Gulf of Mexico coast to the Great Plains and Midwest.
Why it matters: This extreme heat poses serious health risks, particularly for vulnerable populations, and is indicative of worsening climate conditions.
The National Weather Service (NWS) has issued heat alerts for at least a dozen states, impacting 40 million Americans, including regions from Montana to Texas and Florida.
Temperatures are expected to range from 95-105°F (35-40°C), with some southwestern desert areas potentially reaching 120°F (48°C).
Heat is the deadliest weather phenomenon in the U.S., with high humidity and elevated nighttime temperatures compounding the risks.
Vulnerable groups include older adults, pregnant individuals, young children, and those with existing health conditions.
Driving the news: The current heat wave is part of a series of extreme weather events exacerbated by climate change, leading to more frequent and severe heatwaves.
Forecasters predict that the elevated heat will persist into the coming week, trapped by the heat dome, which acts as a lid, holding heat in place.
In addition to the extreme heat, 88 wildfires are currently being fought across the U.S., fueled by the dry and hot conditions.
State of play: Cities across the affected regions are bracing for record-breaking temperatures, with some communities already experiencing prolonged heat.
Palm Springs, California, and Phoenix, Arizona, are forecasted to see temperatures exceed 110°F (43°C) from July 24-27, 2023.
Arizona's capital has recorded 24 consecutive days with temperatures above 110°F, and Tucson may tie its record of 39 days at or above 100°F.
El Paso, Texas, is experiencing a record stretch of 38 days at or above 100°F.
At least four heat-related fatalities have been reported in Texas' Tarrant County, highlighting the severe impact of the heat.
The big picture: The increasing frequency of heatwaves is a stark reminder of the broader climate crisis driven by fossil fuel emissions.
Andy Pershing, chief program officer at Climate Central, stated, "We are experiencing exactly what the climate models in the 1990s said we should experience now," emphasizing the correlation between climate change and extreme heat.
Western Europe is also grappling with severe heat, with the UK facing its hottest June on record and multiple heatwaves impacting public health and emergency services.
In France, an estimated 5,700 heat-related deaths occurred during a recent heatwave, underscoring the deadly consequences of extreme temperatures.
What they're saying: Experts are increasingly concerned about the implications of these heatwaves on health and safety.
Friederike Otto, a climate science professor at Imperial College London, warned that the climate crisis is making every heatwave hotter and more likely to occur.
The UK Health Security Agency expanded heat health alerts across England, indicating potential impacts on health services due to high temperatures.
By the numbers: The statistics reveal the severity and reach of the current heatwave.
Over 130 million Americans are under moderate to severe heat risk conditions, with heat indexes reaching dangerous levels.
Las Vegas has tied its record of 10 consecutive days at or above 110°F set in 1961, with temperatures expected to remain dangerously high.
Miami, Florida, has recorded a heat index high of 100°F for a record 43 days in a row, surpassing the previous record of 32 days.
What's next: As the heatwave continues, authorities are urging residents to take precautions.
The NWS advises limiting outdoor activities, staying hydrated, and ensuring access to air conditioning or cooling centers.
As temperatures rise, the risk for heat-related illnesses increases, particularly for those without air conditioning.
Emergency services are on high alert as they prepare for potential spikes in heat-related emergencies.
This latest heatwave serves as a stark reminder of the urgent need for climate action and public health preparedness as extreme weather events become increasingly common.
