Earth Institute Scientists Drill Into the Oil Spill
Earth Institute scientists have begun research into the Gulf oil spill’s physical and ecological impacts, both on land at sea. While much attention has focused on surface oil washing up along the shores of Gulf coast states, one cruise starting in mid-August will study the location and magnitude of subsurface oil plumes, and their effects…

Core of the Matter
A final note (for now) on the expedition to recover ice cores from the top of Puncak Jaya in Papua, Indonesia: the cores arrived safely on Thursday, July 22, at Ohio State University’s Byrd Polar Research Center, and are now in a special freezer. In coming months, the team hopes to extract and interpret climatic…

Ice on Ice
I have reached Jakarta, and so have the ice cores, which are being kept frozen while awaiting air shipment to the United States. The rest of the team has already returned to their homes. Next for me: back to sea level, on two research cruises that will add oceanographic information to the data we gathered on Puncak Jaya.…

Connecting Young and Old
Nano and I took the train to Rome to meet a colleague for lunch, and after we explored the old city. I have been through Rome a number of times, making my way to and from Calabria, but this was my first time really seeing the city. Nano was a fantastic tour guide. He was…

Hiking Monte Pollino
I grew up in a family that drove on vacations, be it six hours to the beach, eight hours to see relatives, or three days to Idaho. So the seven hour drive from Calabria to Rome is no big deal, although the lack of air conditioning does make it undesirable. When I tell my friends…

Finished, as the Glaciers Fall Apart
We have finished our mission at Puncak Jaya and removed the ice cores, along with all camps and people from the field. Currently, we are in the coastal city of Timika for a few days, drying out our field equipment and tents. These are the first glaciers we have ever drilled where it rains almost every day–and…

Fitting Calabria through a Rocky Doorway
One of the challenges of studying the Calabrian subduction zone is the enormous variation over relatively short distances. Etna is located just 120 kilometers from Stromboli, yet the volcanoes have completely different sources of magma. Fluvial conglomerates in the Crotone Basin have lots of chert, yet conglomerates of the same age just 15 kilometers to…
COP31, the 2026 United Nations Climate Change Conference, aims to advance dialogue, strengthen consensus, and accelerate climate action on a global scale. From November 9–20, 2026 in Antalya, Türkiye, heads of state, ministers, scientists, business leaders, and civil society will gather to advance efforts in emission targets, climate finance, and adaptation and resilience. Once again, our experts, students, and global thought leaders from Columbia Climate School and across Columbia University are contributing to key events, sharing insights, and helping shape the dialogue toward ambitious, science-based solutions.
