Sea ice plays many important roles for the global climate: Its white surface can reflect energy back into space, helping the ...

The Arctic Ocean likely had the smallest winter ice cover in 47 years of satellite records this season, with just 5.53 ...

UN weather agency issues ‘red alert’ on climate change after record heat, ice-melt increases in 2023 The U.N. weather agency is sounding a "red alert" about global warming, citing record ...

Antarctica’s massive ice sheet looks flat ... rift valleys that emit high levels of geothermal heat—and hence, lots of lubricating melt water. As subglacial rivers flow into the sea, they ...

Researchers found increased meltwater and rain explain 60% of a decades-long mismatch between predicted and observed temperatures in the ocean around Antarctica.

New research reveals that Arctic sea ice loss can disrupt weather worldwide, making California drier while increasing winter humidity in parts of Europe. Using advanced models, scientists isolated ...

Part of the system that pumps water, heat and nutrients around the globe is at risk. Climate change could slow the Antarctic ...

Ice serves as a natural shield for both the Earth and its oceans. Its bright, reflective surface helps bounce excess heat back into space, playing a crucial role in regulating the planet’s temperature ...

The system regulates Earth’s climate and pumps water, heat and nutrients around the globe. But fresh, cool water from melting Antarctic ice is diluting the salty water of the ocean, potentially ...
