Will Polar Bears Survive in Their Natural Habitat to 2050?


















The rate of spring sea-ice decline seems to be increasing. This is good news for international shipping, but very bad news for polar bears.

Reminder: my prediction for policy is that countries will not start taking climate change, and the need for stringent climate policies, seriously until the occurrence of some "catalytic event," such as the disappearance of polar bears from substantial segments of their natural range, which the National Snow and Ice Center at the University of Colorado has predicted will occur by the middle of this century (under a business-as usual scenario) (see here).
