On every continent and ocean, Earth Institute field researchers are studying the dynamics of climate, geology, natural hazards, ecology and other subjects with direct applications to the challenges facing humanity.
An all-purpose guide for journalists covering disasters, natural and manmade.
Up to now, it has been a mystery why much of the fresh water resulting from the melting of Antarctic ice shelves ends up in the depths instead of floating above saltier, denser ocean waters. Scientists working along one major ice shelf believe they have found the answer.
Scientists at Columbia University’s Earth Institute will present important findings at this year’s meeting of the American Geophysical Union, the world’s largest gathering of earth and space scientists.
Due to warming climate and increasing human exploitation, far northern forests and the tundra beyond are undergoing rapid changes. In northern Alaska, scientists from Columbia University’s Lamont-Doherty Earth Observatory and other institutions are studying the responses of trees at the very edge of their range.
In northern Alaska’s Brooks Range, the earth as most of us know it comes to an end. The northern tree line-a boundary that circles all of earth’s northern landmasses for more than 8,300 miles, and forms the planet’s biggest ecological transition zone–runs through here. Scientists from Columbia University’s Lamont-Doherty Earth Observatory are studying how climate may change it, and the tundra beyond.
A new film takes viewers from the eastern highlands of India to the booming lowland metropolis of Dhaka, the capital of Bangladesh–and explores an ever-more detailed picture of catastrophic earthquake threat that scientists are discovering under the region.
With the approach of Hurricane Matthew, here are a few of the many scientists at Columbia University’s Earth Institute who can help journalists cover the story.
A new white paper reviews climate impacts already underway in the Arctic, and examines further changes expected to take place even if the world meets the goals of the Paris Agreement. It will be presented today at a meeting at the White House of national-level science ministers and advisors from around the world.
In fall 2015, smoke from agricultural fires in Indonesia blanketed much of equatorial Asia. Schools and businesses closed, planes were grounded and tens of thousands of people sought treatment for respiratory illnesses. In a new study, researchers estimate that the smoke caused upward of 100,000 deaths across Indonesia, Malaysia, and Singapore.
