The past eight years are the warmest since modern record keeping began in 1880.

Will overshooting 1.5°C of warming push us over climate tipping points, triggering irreversible and abrupt changes?

Seals have been a staple for the coastal village of Kotzebue for generations. Rapid changes in sea ice driven by ocean warmth are presenting a challenge for hunters.

Earth Institute researchers are in the field studying the dynamics of the planet on every continent and every ocean. Here is a list of projects.

Current methods to calculate the so-called social cost of carbon largely leave out how many future people our emissions will kill. This study tries to correct that.

Much of the modern understanding of climate change is underpinned by pioneering studies done at Columbia University’s Lamont-Doherty Earth Observatory. Here’s a timeline of significant studies.

New research links reduced glacier cover to higher rates of fungal decomposition of organic material. If these rates continue to rise, it could further disrupt the carbon cycle.

A major firm will facilitate the engagement of commercial enterprise with the university’s global climate and sustainability research.

Swiss ski resorts are using geotextiles to prevent accelerated glacial melting, but researchers have found this strategy too expensive for use in global-scale glacier protection.

The discovery of fossil plants below a mile of Greenland ice indicates that the ice sheet completely melted in the past, and suggests it could rapidly do so again.
