Polar Bears Will Starve If They Don't Eat
Climate change will trigger a dramatic and sudden decline in the number of polar bears, a new study has concluded.
The research is the first to directly model how changing climate will affect polar bear reproduction and survival.
However, these projections are essentially educated guesses, based on experts judging or extrapolating how current population trends might continue as the climate changes.
"mortality will dramatically increase when a certain threshold is passed; for example, while starvation mortality is currently negligible, up to one-half of the male population would starve if the fasting season in Western Hudson Bay was extended from currently four to about six months."
So if you don't eat for a long time you will die, no shit Sherlock. Thank goodness for modern research based on models because; until now, most studies measuring polar bear survival have relied on a method called "mark and recapture".
This involves repeatedly catching polar bears in a population over several years, which is cost and time-intensive.
That measuring stuff in the real world is like so old fashioned....
