Ice caps not likely to face rapid, irreversible melting as previously thought, researcher claims – meaning polar bears could surviveThe polar bear can be saved from extinction – but only if action is taken quickly to make deep cuts to greenhouse gas emissions, a new study shows.The study, published today in journal Nature, conflicts with previous research, which suggested that Arctic temperatures are already on track to exceed the threshold required to trigger rapid, irreversible ice loss.Researchers from Polar Bears International said sea ice in the Arctic, which polar bears use as a platform on which to hunt seals and breed, is unlikely to undergo a rapid and irreversible decline when temperatures rise beyond a certain threshold."It's widely believed that nothing can be done to save the polar bear," said author Steven Amstrup of Polar Bears International in Winnipeg, Canada.
