Climate Tipping Point Surpassed: Rising Heat and Mortality Rates in the U.S.

Doug McIntyre and Dave Callaway discuss whether the tipping point for climate change has been surpassed. Callaway believes it has, noting that climate conditions are worsening rapidly. He cites Phoenix’s 54 days over 110 degrees last year, which resulted in 660 deaths. Callaway warns that the number of heat-related illnesses and deaths in the U.S. is likely to increase sharply. McIntyre agrees, emphasizing that extreme heat is the most dangerous aspect of climate change. He explains the concept of the wet bulb temperature, where extreme heat prevents the body from perspiring, leading to fatal conditions. While such extremes have been observed in India and South America, they have yet to become common in the U.S., but this could change soon.
