Polar bears could soon disappear from parts of the Arctic due to global warming, a climate-change expert has warned.
In an alarming sign, scientists have warned that Arctic sea ice is dramatically melting at a faster rate than previously thought, which may accelerate the effects of global warming.
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.
