Tiny microbes called phytoplankton live beneath the ocean’s surface, producing oxygen that is essential to human survival. A new study sheds light on how these all-important diatoms survive and thrive under difficult conditions.

A new paper in PLOS Medicine argues that climate change projections are often misused in health impact studies: they are best suited for shaping public health policies, not for triggering operational actions on the ground.

Young children are far more vulnerable to climate-related disasters and the onus is on adults to provide the protection and care that children need, according to research led by Columbia University scientists.

Geochemist Alex Halliday was appointed the new director of Columbia’s Earth Institute by University President Lee C. Bollinger last December.

As the world continues to urbanize, poorer people and people of color, in particular, are having to move further and further from city centers. Hutson’s research looks at how these people are surviving.

Melting of ice shelves in West Antarctica speeds up and slows down in response to changes in deep ocean temperature, and is far more variable than previously thought, according to new research.

Two scientists affiliated with the Center for Climate and Life at Lamont-Doherty Earth Observatory are leading research that examines some of the ways climate change affects ocean health.
