Attaching the sensors that will help us study erosion rates required vacuum grease, patience, and a lot of masking tape.

On the volcanic Indian Ocean island of Anjouan, scientists are investigating a rock that apparently formed on a far-off continent.

After bad weather and a busy week of packing and preparation, the team is finally ready to strike out on its own in the coldest, driest, and windiest place on the planet.

The team is using two techniques to study weathering and erosion in Antarctica’s McMurdo Dry Valleys.

The Real-Time Earth initiative is upgrading the technological capabilities of Lamont-Doherty Earth Observatory and transforming the way its scientists study our planet.

Fieldwork in Antarctica adds a whole new layer to the meaning of planning. When heavily field based projects are planned, it is common for preliminary fieldwork to precede the larger project.

A team of autonomous ocean robots deployed in January 2018 has carried out the first year-long observations under an Antarctic ice shelf.

On every continent and every ocean, Earth Institute researchers are studying climate, geology, natural hazards and other dynamics of the planet. Here is a list of projects in rough chronological order for the coming year and beyond.

The North Atlantic Oscillation (NAO) is considered a key driver of winter weather patterns over the northern hemisphere. In recent years, research has claimed a correlation between the NAO and the 11-year solar cycle. A new paper debunks that claim.

Inside the Rock and Ice Mechanics Lab, Heather Savage and her team investigate the physics of earthquakes and fault lines.

What’s a bog corer? And how do seeds help scientists learn about the earth’s past? A paleoecologist explains the most important items in her toolkit.

The current megadrought in the American West may be one of the most severe in the past 1200 years—and climate change is partially to blame.

But there’s a pretty simple solution that could protect a lot of people.

The American Geophysical Union fall meeting is being held Dec. 10-14 in Washington, D.C. Here is a chronological guide to key talks and other events from Columbia University’s Earth Institute.

A concerted, multidisciplinary, and international effort is needed to tackle this complexity, scientists argue in a paper released today.

A guide to wildfire experts at the Earth Institute.

I had one last day installing seismometers with the team, then left for Mandalay. After a breakfast with colleagues, I had a free day to explore Mandalay Hill.

On the way back to Kale, we stopped at a Catholic church where one of the seismometers will be deployed. The seismic team is now in Nay Pyi Taw, the capital preparing for the seismic instrument deployment. 

We drove 15 hours over two days to get to Kale, our new home base. Here, we managed to build a monument and install our first GPS station in only one day. Our homemade post-driver worked amazingly well.

The Trump administration is attempting to rescind almost all the policies to fight climate change proposed or enacted by the Obama administration. Could this send us over the climate tipping points?

The Global Famine of 1876-1878 was one of the worst humanitarian disasters in history, killing as many people as World War II. A new analysis suggests it could happen again, only worse because of climate change.

A small team of scientists ventures out onto the Greenland ice sheet to study the forces large and small that are accelerating the melting of the world’s second-largest ice mass.

Scientists and staff from Lamont-Doherty Earth Observatory and the Earth Institute share some of the ways they’re shrinking their carbon footprints.

Using newly refined analysis methods, scientists have discovered that a North Korean nuclear bomb test last fall set off aftershocks over a period of eight months on a previously unmapped earthquake fault nearby.

By enhancing climate models, a project will help to improve forecasts of intense hurricanes like Hurricane Florence.

Experts from around the Earth Institute weigh in on some of the biggest questions about Hurricane Florence.

An extensive investigation by the Reuters news agency has found that many children living on U.S. military bases may be exposed to hazardous levels of lead in family housing units.

Two Lamont-Doherty Earth Observatory scientists affiliated with the Center for Climate and Life are leading research that examines some of the ways climate change affects the health of the ocean.

The American Geophysical Union, the world’s largest and most distinguished Earth and space science society, has announced its newest Fellows, and among the honorees are two Lamont scientists.

The American Geophysical Union honors the outstanding work of three Lamont scientists.

For this early part of the season the goal is to tease apart a record of historic precipitation and temperature for this region using isotopes from leaf waxes collected in the lake sediments.

Researchers from the Lamont-Doherty Earth Observatory are exploring how volcanic inputs are influencing ocean health in Hawaii.

Rising temperatures and humidity could make summers unbearable in the southeastern U.S. and beyond, according to a study published in December.

Snow on Ice is launching into the field with two teams of scientists this summer. The first group, an ‘advance team’ of six women, will focus on lakes where meltwater has collected on the southwestern flank of Greenland bedrock.

The gift will be used to fast-track innovative high-risk, high-reward projects aimed at delivering science-based solutions to address the challenges of climate change.

Even if we limit global warming to no more than 2°C above preindustrial levels, as the Paris Agreement aims, the world is in store for some dramatic changes, according to a new study.

Yutian Wu, an atmospheric scientist seeking to understand how the rapid decline of Arctic sea ice will impact North American weather extremes, is the Center’s newest Fellow.

Thousands of years ago, the West Antarctic ice sheet shrank dramatically—then grew back in an unexpected way.

For anyone who has ever wished there were more hours in the day, geoscientists have some good news: Days on Earth are getting longer. Very slowly.

Intensifying river floods caused by global warming may hamper national economies worldwide, and effects might propagate through global trade and supply networks, a new study says.

Volcanologist Einat Lev shares incredible footage of steam plumes, lava fountains, and more from the Kilauea eruption.

In a new study in Science Advances, researchers at Columbia University show that machine learning algorithms could pick out different types of earthquakes from three years of earthquake recordings at Geysers in California. The repeating patterns of earthquakes appear to match the seasonal rise and fall of water-injection flows into the hot rocks below, suggesting a link to the mechanical processes that cause rocks to slip or crack, triggering an earthquake.

A new study has uncovered when and why the native vegetation that today dominates much of Australia first expanded across the continent.

Columbia scientists recently visited the Caribbean island of Barbados, whose fossilized coral reefs contain an exquisite record of how the ocean has risen and fallen in the past.

Sediments deposited over thousands of years provide a window to the past—and may perhaps shed light on what happened to the island’s now-lost civilization.

Climate scientist Radley Horton is bringing the effects of sea level rise to the attention of decision-makers and fostering discussions to help society confront climate change.

An international collaboration will study the wasting of the Thwaites glacier, which already accounts for around 4 percent of current global sea-level rise, and could collapse within decades or centuries.

Polar scientists Marco Tedesco and Robin Bell provide a primer on how climate change will impact our coastlines.
