A massive Antarctic lake has unexpectedly gone, vanishing into the ocean with more water than Lake Erie. Satellite images captured its death before and after the 600-750 million-cubic-meter (21-26 billion cubic feet) lake drained through the ice shelf below, and researchers believe it might reveal a lot about the region's ice stability.

Even though Antarctica's margins and the rest of the world are now experiencing unprecedented temperatures, the researchers cannot establish that climate change is to blame. It would definitely make sense, given that even the most hostile regions on Earth feel the heat, with recent temperatures in the Arctic Circle reaching 48 degrees Celsius.
