Using old tree rings and archival documents, historians and climate scientists have detailed an extreme cold period in Scotland in the 1690s that caused immense suffering. It may have lessons for Brexit-era politics.

Research led by Columbia University's Paul Olsen suggests that a massive volcanic winter may have frozen the tropics during the dawn of the dinosaur age.

A team of researchers led by Fred Jiang at Columbia's Data Science Institute is designing an intelligent headphone system that warns pedestrians of imminent dangers.

Scientists have identified systematic meanders in the northern jet stream that cause simultaneous crop-damaging heat waves in widely separated regions—a previously unknown threat to global food production that could worsen with warming.

On a peninsula within sight of New York City, researchers are studying trees dating as far back as the early 1800s. Rising seas and more powerful storms, both fueled by climate change, could eventually spell their end.

A new study led by researchers at Columbia's Data Science finds that diversifying India's crops could provide better nutrition for 200 million undernourished people.

Columbia researchers suggest radiation that lights the densest objects in our universe is powered by the interplay of turbulence and reconnection of super-strong magnetic fields.
