A perilous heat dome is projected to hover over fourteen states in the United States this week, elevating temperatures beyond 100 degrees Fahrenheit throughout the South and Midwest and posing threats of record-breaking highs in multiple cities. The National Weather Service has issued warnings for extreme heat across a vast region stretching from Texas to Indiana. Health officials alert that older adults and young children are at significant risk. Power grids in Texas and the Southeast are under considerable stress. At least three states have already set up emergency cooling facilities. Researchers attribute the escalating heat dome phenomenon to rising ocean temperatures and the ongoing El Nino system.
