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.

As a result, by 100 million years ago, the forests of Victoria included an open conifer-dominated forest canopy. The subcanopy beneath was made up of seed ferns and ferns. Flowering plants and ferns ...

In fact, 16 years passed. The ice cap has plenty of ice, even in summer. Yet nobody calls him on it. “They absolutely should be calling him on it,” says Lueken. Myth 2: Polar bears are going ...

Ice fields on an Arctic island have shrunk 50 percent in the past 50 years and will be gone in 50 more, scientists said this week. IE 11 is not supported. For an optimal experience visit our site ...

"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 ...

Their findings were published in the journal Alcheringa and represent the first-ever detailed reconstruction of Early Cretaceous polar landscapes. As flowering plants began to appear around 113 ...

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 ...

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.
