Tests of water taken near the site where as much as 80,000 tons of coal ash spilled into North Carolina’s Dan River showed high levels of toxics such as arsenic and lead, according to the environmental group Waterkeeper Alliance, which took the tests.

Warming temperatures are expected to have a significant impact on popular ski resorts around the world as snowpack melts. In Sochi, officials ensured snow would be available by using insulated blankets and snow guns.
