When the Sahara Turned to Sand
The Sahara wasn’t always a desert. Trees and grasslands dominated the landscape from roughly 10,000 to 5,000 years ago. Then, abruptly, the climate changed. A study by Lamont-Doherty’s Peter deMenocal says it took just a few hundred years to happen.

The Arctic’s Secret Garden
Lamont-Doherty Earth Observatory marine biologists Craig Aumack and Andy Juhl spend a month each spring in Barrow studying the algae dwelling in and under the sea ice. Their goal is to learn more about the different species of algae that compose these communities and their role in the Arctic marine food web.

Exploring New Zealand Climate Change in Groundwater
Alan Seltzer, a senior at Columbia University, traveled to New Zealand this past summer to work on field experiments aimed at reconstructing temperatures in the region over the last 20,000 years. His adviser, geochemist Martin Stute, is working closely with colleagues at Lamont-Doherty to understand how the southern hemisphere came out of the last ice…

Summer Heat Wave May Have Triggered Landslide on Lonely Alaskan Glacier
A massive landslide in Alaska’s snowy Wrangell-St. Elias mountain range in July may have been caused by a summer heat wave making some slopes more vulnerable to collapse, says the Lamont-Doherty scientist who first discovered the avalanche.

Q&A: Climate Change, Drought and the Future
“One of the ways that climate change is going to manifest is through warmer temperatures. … What we are seeing, in line with our projections, is that even if you assume constant precipitation, the temperature effects are so large that it is going to dry things out. This is going to have really big impacts…

Seismology as Performance Art
Ideally, seismic stations are sited in remote, quiet locations. But other considerations are important for a good station, particularly security. As a result, we placed most of our stations in towns near schools, hospitals or town halls, where people could keep an eye on them.
The first Earth Day in 1970 ignited a movement to stop polluting our planet. Today, our scientists and experts are tackling the most pressing challenges to achieve real-world impact. This Earth Day, join us in our commitment to realizing a just and sustainable future for our planet. Visit our Earth Day website for ideas, resources, and inspiration.
