The polar bear is doomed because the melting of the Arctic ice cap is not reversible. Within 50 years, it will be gone. And if it's gone, there is no place for polar bears to live.

The sustained warmth resulted in no polar ice caps, high sea levels and flooded continents. The geographic distribution of land masses was also very different back then.

Likewise, when the islands cooled, the plants died out because they were unable to survive under blankets of ice. Seeds of hope. Climatologists project the polar regions are going to experience the ...

"The earliest ice-free conditions (the first single occurrence of an ice-free Arctic) could occur in 2020–2030s under all emission trajectories and are likely to occur by 2050," the authors write.

In a year when the Arctic ice cap has shrunk to the lowest level ever recorded, a new analysis from Seattle scientists says global warming will accelerate future melting much more than previously ...

As the planet warms, the polar ice caps are melting. That water flows into the oceans, particularly in the lower latitudes, making our planet bulge at the equator — and adding time to the day.

Mars’ polar ice cap is slowly pushing its north pole inward That, plus data from the InSight lander, gives us a new view into Mars' interior. John Timmer – Feb 28, 2025 4:47 pm ...
