When we think of global climate change, what comes to mind? Rising seas? Melting glaciers? Shrinking sea ice? How about diminishing ocean oxygen levels?
A rapidly-growing crack in the fourth-largest ice shelf in Antarctica has scientists watching for it to break off entirely. By early February, the crack in the Larsen C ice shelf was more than 100 miles long and some parts of it were 2 miles wide. In the two-month period between December and February, the crack grew by 17 miles, a pace of about five football fields a day.
Bolivia’s second largest lake has nearly disappeared. Lake Poopó, a saltwater lake located in a shallow depression in the Altiplano Mountains, used to cover an area about the size of Los Angeles. While it’s not the first time the lake has dried out, scientists believe its recovery hangs in the balance due to the combined stress of drought, climate change, and water diversion.
