Why are Past Surface Temperatures and CO2 Concentrations Important?
By burning fossil fuels for heating, electricity, transportation and other purposes, humans add CO2 to the atmosphere. Yet, by comparing ways in which the Earth’s temperature, CO2 concentration, sea level and ice sheets have changed in the past, we are able to learn valuable lessons about the climate system of today and tomorrow.

Photo Essay: A Day in the Life of the Hudson River
Once a year, Piermont Pier becomes a field station, and local students, a team of environmental investigators. On Tuesday, scientists at Lamont-Doherty Earth Observatory led students through a series of field experiments designed to teach them more about the Hudson River.
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
