Is the polar bear really going to become extinct?
Last year more than 250 scientists produced the most comprehensive report on climate change in the Arctic (The Arctic Climate Impact Assessment). This report says that polar bears could become extinct by the end of this century unless actions to curb global warming are taken. They are very unlikely to survive as a species if there is an almost complete loss of summer sea ice cover, which is projected to occur before the end of this century by some climate models.
