Warming world creates hazard for Alpine glaciers


              A view taken from a rescue helicopter of the Punta Rocca glacier near Canazei, in the Italian Alps in northern Italy, Tuesday, July 5, 2022, two days after a huge chunk of the glacier broke loose, sending an avalanche of ice, snow, and rocks onto hikers. Italy was enduring a prolonged heat wave before a massive piece of the Alpine glacier broke off and killed hikers on Sunday and experts say climate change will make those hot, destabilizing conditions more common.
