Scientists succeeded in thickening and lightening Arctic ice using seawater in an innovative climate experiment.

For two decades the nitrate that feeds the base of the Arctic food web has been draining away. A long record of ocean ...

A hidden change in Arctic geography may have disrupted the ice age rhythm and transformed the global climate over thousands ...

Arctic sea ice helps cool the planet and influences weather patterns around the world, but it is disappearing faster than ever as the climate warms. Scientists have now developed a new forecasting ...

Scientists have identified a tipping point that has amplified El Niño’s effect on sea ice loss in the Arctic. For years, researchers have known of a feedback loop linking the El Niño-Southern ...

When it comes to global warming and climate change, we often hear news stories about tipping points where Earth's systems shift into a new and dangerous state. One such may have been reached in the ...

Earth’s oceans absorbed another record volume of heat in 2025, reinforcing a pattern that climate scientists say is accelerating ice loss in the Arctic and storing energy that will shape weather ...

Melting glaciers and ice sheets are raising sea levels while the Arctic is poised to log one of its worst winters on record. Here are some key points about the planet's ice as human-induced global ...

As the sea ice melts due to climate change, the trend of polar bears getting thinner and having fewer cubs has been well documented in areas such as Baffin Bay, a stretch of ocean between Greenland ...

Rising temperatures and rapidly melting sea ice threaten polar bears across the Arctic. But the bears living 800 miles north of the Arctic Circle have stayed surprisingly fat, researchers report ...
