The scientist and his family tracking melting glaciers for nearly half a century

The world's glaciers are receding at an alarming rate, losing more than a trillion tons of ice a year. Fueled in part by climate change, it's driving sea levels higher, which could threaten coastal communities around the world. One man, alongside his family, has seen the melt firsthand every year for nearly half a century. Special correspondent Ben Tracy of Climate Central reports.
