Time Reports: Climate Change Pushes Polar Bears Towards Extinction, Study Finds
If we do not reduced the amount of greenhouse gas emissions, polar bears will likely die out by the end of the century, according to a new study by Nature Climate Change.
Rising temperatures have put the natural habit of polars at risk, as sea ice and hunting opportunities disappear.
The study found that declining sea ice has already pushed some polar bear populations to their survival limit. If greenhouse gas emissions stay on their current track, only polar bears living in the Queen Elizabeth Islands in Canada’s Arctic Archipelago will remain by the end of the century. But even if emissions are curbed, sea ice will continue to melt in the coming years as a result of the current levels of carbon in the atmosphere, leading to a decline of polar bears, particularly in southern Arctic region
The study analyzed 13 of the world's 19 polar bear populations. The study found that experts can estimate the number of days the bears can fast before their ability to reproduce is impacted.
They determined that the amount of time bears would have to fast surpassed the amount of time polar bears are capable of fasting. The result is that by 2040, some polar bear populations living in southern Hudson Bay and Davis Strait in Canada will begin to experience reproductive failure and by 2080, the majority of polar bear populations will be likely be afflicted.
Polar bears are the largest terrestrial carnivore on the planet that have faced extinction before in 1965.
We need to work together to prevent the disastrous effects of climate change.
