Does temperature control atmospheric carbon dioxide concentrations?
A record of temperature and atmospheric CO2 from Antarctic ice cores shows the tight relationship between the two over the past 800,000 years (see figure). It is frequently asserted that changes in Earth’s temperature or, more specifically, the temperature of the ocean, caused atmospheric CO2 concentrations to vary over that time period. The underlying principle…

Why Women Matter
Megatons of carbon dioxide, radiative forcing, technology deployment, cap-and-trade systems: this is the common vocabulary of climate change. Concepts of equality, justice and ethics are relative latecomers to this highly specialized and technical world. Where they have emerged, terms like ‘climate justice’ usually refer to the interests of developing nations as a whole, reflecting the deep…

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…

Event: Himalayan Glaciers and Asia’s Looming Water Crisis
Columbia Water Center, The Asia Society and The Economist are cosponsoring the event Himalayan Glaciers and Asia’s Looming Water Crisis, Wednesday July 14, 2010, 6:30pm at the Asia Society.
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
