Urgent steps are required to protect the planet`s last great wilderness Antarctica, which is likely to face more critical threats than ever before, an international team of researchers, has warned.

Thickest Arctic Sea ice melting much faster

The thicker ice, known as multi-year ice, survives through the cyclical summer melt season, when young ice that has formed over winter just as quickly melts again.
