The research, published by Nature Climate Change, assessed global warming impact in polar bears habitats and surviving strategies, like seal hunting on the ice. This circumstance could lead them to more extended fasting periods and reproductive failure.
“It’s been clear for some time that polar bears are going to suffer under climate change,” University of Toronto Scarborough biologist and research author Péter Molnár said.
If greenhouse gas emissions continue as for current ratios, the polar bears would only remain in the Queen Elizabeth Islands in the Canadian arctic archipelago by the end of the century. Even under a gas reduction situation, by 2080, most polar bears clusters would face reproductive limitations.
Climate Change is the defining issue. From shifting weather patterns that threaten food production, to rising sea levels that increase the risk of catastrophic flooding, the impacts of climate change are global in scope and unprecedented in scale. @UNFCCC@UNClimateSummitpic.twitter.com/PCLxAcphvE
