Texas Braces for Worsening Heat Wave, Puts Millions on Alert.

A heat wave in Texas is expected to worsen and expand, putting over 40 million people under heat alerts. High temperature records have been broken, and the heat index could reach as high as 120°F. Rising global temperatures due to the burning of fossil fuels are making heat waves worse, and changes to the jet stream are causing more persistent weather patterns. The heat dome over Texas is causing an uptick in severe weather, and the CDC recommends staying in air-conditioned buildings, drinking plenty of water, and wearing loose-fitting clothing to protect against extreme heat events.
