One of the oldest puzzles in climate science is why ice ages deepen: atmospheric carbon dioxide dropped during glacial ...

Scientists have uncovered a surprising connection between Earth's opposite poles that may help explain how the planet plunged ...

Sign up for the Morning Brief email newsletter to get weekday updates from The Weather Channel and our meteorologists. The warming climate in polar regions may ...

As climate change advances, the ocean's overturning circulation is predicted to weaken substantially. With such a slowdown, scientists estimate the ocean will pull down less carbon dioxide from the ...

Every southern spring and summer, sea ice around Antarctica melts with the change of season. The melt injects fresh water ...

Scientists have found that the AMOC may be far more vulnerable to rapid warming than to temperature alone. When warming happens slowly, the ocean can adapt, but at faster rates similar to today’s, the ...

Climate change-driven shifts in the circulation of waters to the deepest reaches of the ocean around Antarctica, which could reverberate across the planet and intensify global warming, are happening ...

René van Westen watched in alarm as freshwater from a melting Arctic poured into the North Atlantic, diluting the normally dense and salty sea. The influx gradually slowed the aquatic conveyor belt ...

The Antarctic Circumpolar Current (ACC) plays a central role in regulating the global ocean circulation, climate and Antarctic Ice Sheet dynamics. Yet the spatiotemporal variability of the ACC during ...

Changes in ocean circulation can increase oxygen in some regions while decreasing it in others, creating local winners and losers for marine life. Studying warmer periods in ancient oceans can help ...

During glacial epochs, changes in large‐scale ocean circulation exerted a profound control on atmospheric carbon dioxide levels and global climate. Cooler temperatures, expanded sea ice and altered ...
