Fossil fuel companies are ramping up production of virgin plastics, with huge potential consequences for climate and the environment.

Now that the ‘Solid Carbon’ project has won a spot in the MacArthur foundation’s 100&Change competition, what’s next for carbon capture and storage?

Women scientists play an essential role in our mission to understand how the planet works, how humans are changing it, and how to build a sustainable future.

In your Oscar speech, don’t just preach sustainability — wear it.

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.

The award posthumously recognizes Takahashi's research around ocean uptake of carbon dioxide emissions.

Dan Westervelt, a 2019 Center for Climate and Life Fellow, received funding to address the ongoing air pollution crisis in three large sub-Saharan African cities.

Long-lived compounds implicated in a third of overall global warming from 1955 to 2005.

My last days in the field brought us to monuments in a makeshift home near the ocean, a flooded field next to a school, and adjacent to a jute mill. Most of us now head back to Dhaka, the capital. Céline will stay on a few more days, then Hasnat with Saif and Nahin will continue until all the monuments are resurveyed.

We continued our GPS surveys of monuments to measure land subsidence. While the work generally went very well, we faced challenges from obscured or tilted monuments. We also struggled with large traffic delays, particularly at unpredictable ferry crossings.

A new study uncovers a previously undocumented relationship between erosion and wind speed.

Evidence suggests that this major ocean current, which influences the weather in parts of Europe and the U.S., is already changing.

The PlastiX-Snow project will track microplastics that contaminate Earth’s most remote and pristine locations.

Warming temperatures create two major drying trends, jeopardizing corn and soybean crops.

Using old tree rings and archival documents, historians and climate scientists have detailed an extreme cold period in Scotland in the 1690s that caused immense suffering. It may have lessons for Brexit-era politics.

A variety of undergraduate research assistant positions are available. Apply by January 29, 2020.

The “walking rock” track suggests that a massive volcanic winter may have frozen the tropics during the dawn of the dinosaur age.

On a peninsula within sight of New York City, researchers are studying trees dating as far back as the early 1800s. Rising seas and more powerful storms, both fueled by climate change, could eventually spell their end.

A chronological guide to key Lamont talks and other events at the Dec. 9-13 American Geophysical Union meeting in San Francisco.

A bay in Antarctica has been named after biological oceanographer Hugh Ducklow to celebrate his contributions to Antarctic research.

New study challenges many climate scientists’ expectations that plants will make much of the world wetter in the future.

Kevin Griffin uses remote sensing to track the daily rhythms of trees. His work is helping to bring tree biology to life for students and the general public.

Using drones, laser scanners, and high-resolution models, researchers hope to find out more about the processes driving rapid melting in this region.

On Saturday, October 5, Columbia University’s Lamont-Doherty Earth Observatory opened its doors to the public once again.

A paleoecologist explains why it’s actually a bad idea to “drain the swamp.”

Visit us in Palisades, NY, for hands-on, family-friendly science activities and lectures — including a new panel that will address the challenges of reporting the climate story.

Short answer: Moderation is key.

Journalists at Univision teamed up with Lamont scientists to test how well Newark’s lead filters are working. The results support new findings from city officials.

Dozens of Earth Institute and Lamont staff and students took part in New York City’s Climate Strike march.

Two Months in the Southern Ocean, for Science Under the leadership of Lamont-Doherty Earth Observatory scientists, two different expeditions sailed to the stormy Southern Ocean to learn more about Earth’s climate history.

A team of researchers taught social science students to test for high fluoride levels in their own villages, and experimented with creative ways to get the word out about the dangers of fluorosis.

Join Lamont's Center for Climate and Life and our Earth Institute colleagues at a groundbreaking New York City climate event designed to inform and inspire.

Scientific experts from Lamont and leading finance professionals at AllianceBernstein are collaborating to create an intensive curriculum focused on how climate change can affect economic and financial outcomes.

Park Williams and Richard Seager, climate experts at Lamont-Doherty Earth Observatory, discuss why California wildfires are expected to expand and intensify with climate change.

A student research project unveils that tiny plastics in laundry detergents and fabrics could potentially have a big impact on ocean health.

Two months at sea, collecting drill cores in the stormiest ocean on the planet, can feel both extremely epic and fairly routine.

Artificial and modified organisms could become essential tools to fight climate change, clean up pollution, protect biodiversity, and more.

A new study shows, for the first time, evidence of a link between human-caused global warming and melting of the West Antarctic Ice Sheet.

Lower air pollution levels saved an estimated 5,660 lives in New York State in 2012, compared to 2002 levels, according to a new study.

We added a campaign monument to the tide gauge at Khepupara on the way to our last GPS and SET installation site at Patuakhali. We faced challenges such as bad roads and broken bridges, and leeches, but got the work done. The field work was now coming to a close.

We replaced the GPS at Khulna University, then met some colleagues in Barisal. We continued to Khepupara and the beach at Kuakata for more installations. The beach on the Bay of Bengal is fresh water in the summer due to the enormous water discharge at the Ganges-Brahmaputra Delta.

Silting rivers and bad roads made it difficult to find a last site. After a successful installation and an upgrade to an existing GPS site, we left the boat for land. We then discovered the local river had washed away some of our equipment.

We sailed to Hiron Point in the Sundarban Mangrove Forest to upgrade old and install new equipment. I have been to this beautiful remote site several times before. After competing the work, we sailed for over a day to reach our next site on a primary school roof.

By working a 16-hour day, we managed to get both GPS and SETs completed at our first field site. We then sailed into the Sundarban Mangrove Forest, the world’s largest, to visit an existing site and make measurements.

Study picks apart factors that caused severe, long-lasting droughts and suggests increased risk for future.
