Melting polar ice is delaying the leap second by three years, pushing it from 2026 to 2029, the report found. “Part of figuring out what is going to happen in global timekeeping ...

Polar sea ice is ever-changing. It shrinks, expands, moves, breaks apart, reforms in response to changing seasons, and rapid climate change. It is far from a homogenous layer of frozen water on ...

The impacts of human-caused climate change are so overwhelming they’re actually messing with time, according to new research.. Polar ice melt caused by global warming is changing the speed of ...

If it works, polar geoengineering like sea-ice thickening could affect the entire Earth. Arctic sea ice is like a big mirror, reflecting up to 90 percent of the sun’s radiation back into space ...

Earth’s major climate goal is too warm for the polar ice sheets, study says. If Earth stays at its current levels of warming — below policymakers’ goal of 1.5 degrees Celsius — polar ice ...

Polar bear equipped with camera collar reveals details of life in the melting Arctic 04:34. Polar bears, unable to thrive on land in Canada's Hudson Bay, are facing greater risk of starvation as ...
