PINEDALE, Wyo. (AP) A climber missing in the area of Wyoming's highest mountain has been found dead. Thor Hallingbye, 41, of Cheyenne, was reported missing Sunday after apparently getting separated from his group near Gannett Peak on Saturday, according Sublette County sheriff's officials.
PUNACA TINTA MARIA, Bolivia (AP) For many generations, the homeland of the Uru people here wasn't land at all: It was the brackish waters of Lake Poopo. The Uru “people of the water” would build a sort of family island of reeds when they married and would survive on what they could harvest from the broad, shallow lake in the highlands of southwestern Bolivia.
Study: Key Antarctic ice shelf is speeding up its collapse

The Pine Island Glacier on the West Antarctic Ice Sheet is responsible for more than a quarter of Antarctica s contribution to global sea level rise over the past decades. Now, a new study shows it is more vulnerable to rapid melting than thought, because climate change is weakening its natural braking system.
Why it matters: At stake is the future of a glacier containing about 160 trillion tons of ice, which if it were all to melt into the ocean would cause about 1.6 feet of global sea level rise.
In the Antarctic circle, robots collect data on melting icebergs. Elsewhere, drones help us study river flows. These are just two examples of how digital technology is helping us better understand climate change.
