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. "But that's not true."According to Andrew
Derocher, a polar bear... - With climate changes, polar bear and
brown bear lineages intertw
