The polar ice caps are melting, and according to a new study, they may be melting twice as quickly as previously thought. Researchers from University College London say some parts of the Arctic could be free of ice within 20 years. “It's also declining in the coastal areas of the Arctic much more quickly than we thought,” said Robbie Mallett, a PhD student at UCL. He continued, “It's going to contribute to a lot of warming, basically. It's going to get hot."
