Tragic Hiking Deaths in Texas Heat

A teenage boy and his stepfather died while hiking in Big Bend National Park in Texas as temperatures rose to 119 degrees Fahrenheit on Friday, the second-highest mark ever recorded in the state. The triple-digit heat wave has broken daily temperature records across Texas and strained the state’s independent power grid. The heat wave is forecast to spread to the Southeast this week. While tying a single heat wave to climate change requires analysis, scientists have no doubt that heat waves around the world are becoming hotter, more frequent and longer lasting.
