A Popular Narrative
Polar bears (Ursus maritimus) are the poster child for the impacts of climate change on species, and justifiably so. To date, global warming has been most pronounced in the Arctic, and this trend is projected to continue. There are suggestions that before mid-century we could have a nearly ice-free Arctic in the summer. This increases the urgency with which we must act to reduce our greenhouse gas emissions to delay or avoid some of the worst consequences of climate change.
