Record humidity made summer heat worse

More than a dozen states experienced record high humidity in July, making summer heat feel more oppressive and dangerous. The Midwest and East Coast regions were particularly affected, with heat index values soaring into the triple digits for extended periods. Cities like Pittsburgh and Washington D.C. recorded their most humid Julys ever. This trend of increased humidity is linked to climate change, which can exacerbate health risks from heat and contribute to more severe storms and flash flooding.
