Hurricane Helene wreaked havoc across the Southeast over the past several days, leaving more than 60 people dead and providing a chilling example of how climate change is worsening storms. Since the hurricane made landfall in northern Florida on Thursday, it killed at least 64 people, including 1-month-old twins and their 27-year-old mother in Georgia, and a couple in their 70s and a 6-year-old relative who drowned in North Carolina, the Associated Press reported Sunday.
