  • Drilling Ancient Mud from Seafloor No Easy Task

    Drilling Ancient Mud from Seafloor No Easy Task

    Yesterday we left our first study region with new samples from the seafloor and a healthy respect for the ocean currents that can erode sediment deep in the ocean. The seafloor we surveyed was heavily eroded and we had to look carefully before finding sites that were promising enough to try sampling. Even then we…

    Our Best Flight Yet

    Evidence of the retreat of glaciers since the last glacial maximum (check), flying over sites of ancient Inuit, Norse and present day settlements (check), and a personal recollection of my own past in this location (check).

  • Emissions from the Cement Industry

    Emissions from the Cement Industry

    A single industry accounts for around 5 percent of global carbon dioxide (CO2) emissions. It produces a material so ubiquitous it is nearly invisible: cement. It is the primary ingredient in concrete, which in turn forms the foundations and structures of the buildings we live and work in, and the roads and bridges we drive…

    Ph.D. Candidate Studies Natural Carbon Storage in Oman

    Amelia Paukert considers herself “environmentally inclined” because of her early exposure to nature and horseback riding in her native Napa Valley, California. Her fascination with the water cycle helped spark her passion for environmental science.

    Albany to Alert

    On the way from Kangerlussuaq to Thule we fly along the coast of Greenland, over Baffin Bay, where the Arctic starts to show its icy face. For me, Greenland is fascinating for its mild temperatures, diverse wildlife in the south and breathtaking frozen state in the north. I also like the Danish pastries served in…

    Through the Looking Glass: Peering Through the Bottom of the Ocean

    Alice stepped through the mirror to see the world beyond, and we peer through the bottom of the ocean to see what is below. Short pulses of sound from the ship are focused on the seafloor, and we listen to the echo and reverberations that return.

    Calmer Seas Ahead

    After a short break due to weather and a bit of fun with Styrofoam cups, we are back in the lab sampling phytoplankton in the Bering Sea. We are using a specialized instrument to determine how well these small plant-like creatures are able to photosynthesize in the ocean, and we continue to learn fun facts…

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.
