Why does sea level change at different rates? How has it changed in the past? Who will be at risk from more extreme weather and sea level rise in the future? Our scientists often hear questions like these. To help share the answers more widely, we created a new app that lets users explore a series of maps of the planet, from the deepest trenches in the oceans to the ice at the poles. You can see how ice, the oceans, precipitation and temperatures have changed over time and listen as scientists explain what you’re seeing and why.

The public is bombarded by information about Earth’s changing climate almost daily, but the people studying the climate system are rarely seen. The Climate Models wall calendar, which provides a unique look behind the science, intends to change that in 2014.

Tourists flock to Italy to see Michelangelo’s David and other iconic hunks of Renaissance stone, but in a trip over spring break, a group of Columbia students got to visit rocks that have shaped the world in even more profound ways. In the limestone outcrops of Italy’s Apennine Mountains, geologist Walter Alvarez collected some of the earliest evidence that a massive fireball falling from space some 66 million years ago was responsible for killing off the dinosaurs. Geologists have trekked to the region since then to study that catastrophic event as well as others imprinted in these rocks.

A flock of young researchers from New York City, Singapore and the Netherlands are testing their skills in the field near Lamont-Doherty Earth Observatory this weekend -- canoeing on Sparkill Creek to take water samples, counting forest species in Tallman Mountain State Park and analyzing soil chemistry.

We are proud to announce that in the new rankings of 140 Earth Science Ph.D. programs by the National Research Council (NRC), our program is ranked at the very top!

Instead of an ice-covered South Pole, picture sub-tropical temperatures and flowering plants. That’s what parts of Antarctica looked like 85 million years ago. How long ago was that? If you’re drawing a blank you’re not alone.
Thinking on geologic time scales does not come easily for many people, and that’s a challenge in teaching earth science, says Lamont-Doherty oceanographer Kim Kastens, in a recent cover story in EOS, a weekly newspaper published by the American Geophysical Union.

The destruction caused by natural disasters such as Hurricane Katrina and human activities such as mountaintop removal mining are powerful examples of how the environment and society are tightly interwoven. But to what extent do, or should, state science curricula in the U.S. seek to investigate or influence the nature of this interaction?

Mikah McCabe wanted "some serious research experience" on global warming or climate change. Hagar ElBishlawi wanted to work in a program affiliated with The Earth Institute. Michael Silberman wanted to work at Lamont because the people there work on the "interesting and important problems."
Each of the undergraduate interns welcomed by Lamont-Doherty Earth Observatory this summer may have had their own reason for applying, but they all have one thing in common: they are some of the best and brightest.
