Photo Essay: Iceland at the Cutting Edge of Climate Change
Iceland has a complicated relationship with climate change. As in much of the far north, global warming is already exerting many effects here–arguably both good and bad. Yet the country contributes relatively little to the warming, since most of its energy comes from geothermal and hydro plants, which produce little carbon dioxide. Now, it is…

An Earth Epic
I hear that the Archean Earth Spewed lava and was hot, (While much later, “Snowball Earth,” Apparently was not), Some have said that life sprung out of Spreading-ridge-type stew, Photosynthesis seems likely Based on carbon records, too.

In the Ice
Several days ago we reached our main work areas along the margin of East Antarctica. Our expedition is relatively late in the season and the seas around Antarctica are starting to freeze.

Closing in on Antarctica
We are less than a day away from our first study area on the continental shelf in front of the Dibble Glacier. As we approach Antarctica we are starting our science program with a 4500 meter deep CTD and multibeam acquisition.

Indian Sundarban
We arrived in Kolkata, and filmed by the Hooghly River. While it is no longer the main channel of the Ganges, it is still the Holy Ganges and we saw a funeral procession spreading ashes of a loved one while filming there. Then a 5 hour trip by car, ferry, rickshaw and boat to the…

Geology and Filming in Mizoram
In the small town of Kolasib, we stayed in Hotel Cloud 9. I had been told since I was a child that I was always off on Cloud 9 and now I was actually here. However, the electricity wasn’t for the first few hours, so showers were cold, but the dinner was hot.

Soon-to-End Mercury Mission May Hold Clues to Earth’s Evolution
NASA’s MESSENGER spacecraft has been orbiting Mercury for the last four years, giving scientists an unprecedented look at our solar system’s innermost planet. But now the craft’s fuel supply is exhausted; inexorably drawn in by Mercury’s gravity, it is scheduled to crash in April. Sean Solomon, director of Columbia University’s Lamont-Doherty Earth Observatory, has been…
AGU25, the premier Earth and space science conference, takes place December 15-19, 2025 in New Orleans, Louisiana. This year’s theme—Where Science Connects Us—puts in focus how science depends on connection, from the lab to the field to the ballot box. Once again, Lamont-Doherty Earth Observatory and Columbia Climate School scientists, experts, students, and educators are playing an active role, sharing our research and helping shape the future of our planet. #AGU25 Learn More
