Scientists Say They Now Know Why Antarctic Meltwater Stays Below Ocean Surface

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.

Photo Essay: Where the Trees Meet the Tundra

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.

Near the arctic circle in northern Alaska, forests begin giving way to tundra. as cold air, frozen soils and lack of sunlight squeeze out trees. Researchers are investigating how warming climate may affect the ecology of this boundary. (All photos: Kevin Krajick) CLICK TO VIEW A SLIDESHOW

Where Trees Meet Tundra, Decoding Signals of Climate Change

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.

2015 Indonesia Fires Killed 100,000 People, Says Study

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.
