Tiny particles bubbling up from melting Arctic sea ice play a key role in cloud formation, suggests new research. The discovery may explain why Arctic clouds behave differently — and lead to ...

Sea ice is not just solid frozen water. It's riddled with tiny pockets and channels of liquid brine. Whether those pockets connect to form pathways determines whether seawater, nutrients and gases can ...

Add Yahoo as a preferred source to see more of our stories on Google. Many species, not least polar bears, depend on sea ice to breed and feed. (Olivier MORIN) (Olivier MORIN/AFP/AFP) Arctic sea ...

I walked out onto the frozen Arctic water off Utqiagvik, Alaska, for the first time, I was mesmerized by the icescape. Piles of blue and white sea-ice rubble several feet high gave way to flat ...

Antarctic sea ice has entered a persistent low state that appears inconsistent with the natural variability of the past century, and a growing body of research links this “regime shift” to warming ...

Tiny particles bubbling up from the tops of melting sea ice into the Arctic sky may be a key, understudied element of cloud formation in that climate-sensitive region.
