The Lethal Impact of Extreme Heat: How Climate Change is Affecting Cities Like Las Vegas and Phoenix

Doug McIntyre and David Callaway discuss the extreme heat events in cities like Las Vegas and Phoenix, highlighting recent record temperatures—120°F in Las Vegas and over 110°F for 54 days in Phoenix. They point out that while many have access to air conditioning, a significant portion of the population in these cities does not, making extreme heat potentially lethal. They also address the vulnerability of electric grids due to rising energy demands from AI and other sectors. With climate change intensifying heatwaves, they express concern that this summer might just be the beginning of even hotter conditions in the future.
