Have you ever wondered if polar bears will be extinct?

Polar bears will be extinct in 80 years, the climate crisis may be the cause of the disappearance of polar bears. Most of the polar bear populations of Alaska and Russia will be in serious trouble to perpetuate themselves by 2080 and could mostly disappear by 2100.

There are about 25,000 polar bears left in the north of the planet, but their young may soon face starvation. Due to the increase in temperature, the extent of ice in the Arctic has decreased as never seen before in July, according to the Alfred Wegener Institute of the Helmholtz Center for Polar and Marine Research (Germany), according to the newspaper El Country.

Polar bears cannot get enough sustenance on land, so they depend on ice to hunt and wait for hours in the holes in the ice used by seals to breathe and hunt them, but as the ice decreases due to the climate crisis so could polar bears.

If the current projection of greenhouse gas emissions were maintained, according to a study published by the journal Nature Climate Change.

A change in emissions

The subpopulation (of the 19 that exist now) that may be able to withstand this worrisome fate is the Queen Elizabeth Islands in the High Arctic. If emissions are reacted and mitigated, the scenario shows that subpopulations further south are likely to disappear, but others will resist, albeit with reduced reproduction and population size.
