During his time in Ethiopia, New York-based art director and photographer Diego Arroyo spent time with the Hamar, Mursi, Dassanech, and Arbore Tribes. They, along with several others tribes, make up the 200,000 people situated in Africa’s Great Rift Valley. The people of the Omo Valley are still primarily herders and farmers, living an isolated and simple life. While they have yet to be truly touched by globalization, they could soon disappear. Their way of life is being threatened by a massive hydroelectric dam. (Photo by Diego Arroyo)

The northeastern United States sweltered this week in a scorching summer heat wave, complete with stagnant, sticky air and no winds for relief, forecasters said. Even in a summer already filled with stretches of very hot weather, this week will be stubbornly brutal, with no relief in sight until the weekend brings thunderstorms to the region, they said. "Plain and simple, this week may feel the worst of any week for this summer in the Northeast," said Accuweather.com meteorologist Alex Sosnowski. (Reuters)

In this Thursday, December 1, 2016 photo, Cat Bigney, part of the Oglala Native American tribe, waits on the shore of the Cannonball river for travelers to arrive by canoe at the Oceti Sakowin camp where people have gathered to protest the Dakota Access oil pipeline in Cannon Ball, N.D. So far, those at the camp have shrugged off the heavy snow, icy winds and frigid temperatures. But if they defy next week's government deadline to abandon the camp, demonstrators know the real deep freeze lies ahead.
