Heat Index Rise Outpaces Temperature, Signaling Climate Change Impact

A new study reveals the heat index in Texas is increasing three times faster than actual temperatures, underscoring the urgency to address climate change.

The heat index in Texas, measuring the perceived heat stress, is rising three times faster than actual temperatures, reaching extremes like 167°F at Houston's Ellington Airport due to climate change.
A study by UC Berkeley reveals that current methods to calculate the heat index underestimate the risk of hyperthermia and heat-induced fatalities, highlighting a gap in public awareness.
Heat-associated deaths in Arizona's Maricopa County increased by 50% from 2022 to 2023, with most victims over 50 years old.
Scientists warn that without halting fossil fuel consumption, half of Earth's population could face life-threatening heat stress.
Practical measures like using water and shade are advised to mitigate hyperthermia risks in the face of rising heat indices.
