    Connecting the Dots: Extreme Weather and Climate Change

    Professor Ben Orlove, anthropologist and co-director of the Earth Institute’s Center for Research on Environmental Decisions discusses the connection between extreme weather and global warming, and public perception of climate change.

    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…

    Exploring the Bering Sea Ecosystem

    Our stations have continued to be rich in phytoplankton, while our colleagues are excited by the larval fish they are finding in the southern Bering Sea. Wildlife sightings have included whales, dolphin, and the jawless lamprey fish, and we are settling in for potentially bumpy seas ahead.

    Observations in Nature Outrun Those in Artificial Plots

    The Double-Edged Sword of Geoengineering

    Shooting sulfur particles into the stratosphere to reflect the sun? Dumping iron into the ocean to boost the absorption of carbon dioxide? Could these far-fetched and dangerous-sounding schemes—geoengineering—help avert potentially catastrophic effects of climate change, or would they exacerbate conditions on our ever warming planet?

    Dead Plants Strengthen Beliefs in Global Warming

    Subtle stimuli in the environment exert a strong influence on the way we think about global warming. The notion that surrounding objects unconsciously influence our thoughts and behavior is of interest to individuals who are interested in developing strategies to promote sustainable behavior.

    Climate News Roundup: Week of 4/08

    EU CO2 law could scupper global climate talks, Reuters, Apr 11 A European Union law that charges airlines for carbon emissions is “a deal-breaker” for global climate change talks, India’s environment minister said, hardening her stance on a scheme that has drawn fierce opposition from non-EU governments. U.S. airlines have said they would grudgingly comply,…

    From Sendai to Rio: A Call for Action

    The people living on the northeast coast of Japan had learned to expect large earthquakes. But despite being one of the best-prepared nations, they were caught off-guard by the force of the March 11, 2011, earthquake and tsunami that devastated their coastline and led to the meltdown of reactors at the Fukushima nuclear power plant.

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
