In the Southern Ocean, a Carbon-Dioxide Mystery Comes Clear
Twenty thousand years ago, low concentrations of carbon dioxide in the atmosphere allowed the earth to fall into the grip of an ice age. But despite decades of research, the reasons why levels of the greenhouse gas were so low then have been difficult to piece together. New research, published today in the leading journal…

Doing Science When There’s No Science to Be Done
With an abundance of time and a dearth of work, we have begun to devise ways of doing science before we can actually do science at sea. Among other things, we set up an imaging system to take pictures of particle filters we bring back from the deep sea.

Electoral Politics and Environmental Sustainability
The political consensus for sustainability that could emerge might be based on increased funding for the science of renewable energy, battery technology, energy efficiency and smart grids. It could also include incentives for private sector investment to commercialize new energy technologies, and tax expenditures that make it easier for consumers to adopt these new technologies.
On Saturday, October 17, 2026 from 10am to 4pm, Lamont-Doherty Earth Observatory Open House—our biggest, best science fun and discovery event of the year—will take place on our beautiful campus in Palisades, NY. Mark your calendar and join us for this free, family-friendly celebration of science! RSVP Today!
