  • Learning from El Niño as La Niña Odds Rise

    Learning from El Niño as La Niña Odds Rise

    Although El Niño is weakening, its ramifications continue to be felt around the world. Drought and resulting food insecurity is one of the major implications for southeast Asia, eastern and southern Africa, Central America and the Caribbean. Sixty million are in need of emergency relief today, according to the United Nations.

  • The Climate Crisis and the Transition to a Renewable Economy

    What I am betting on is the growing sense of awareness and understanding of environmental issues among the people of the world. It could be that my personal perspective is a little warped. I’ve seen the environmental issue move from the outer fringes to the center of our political agenda.

  • Fossil Fuel Companies Need to Become Renewable Energy Companies

    No one should underestimate the scale of the challenge that confronts humanity. It will require new technologies and changes in infrastructure, organizational capacity, economic incentives and public policy.

  • Moving the Global Economy Toward Sustainability

    Using something finite and dumping it into a hole in the ground is less efficient and more costly than a system build on photosynthesis, renewable resources, and reuse of finite resources. In other words, an organization managed according to the principles of sustainability should be able to outcompete the organization sticking to the old, polluting…

  • Filling a Climate Gap and Helping Rwandan Farmers

    Filling a Climate Gap and Helping Rwandan Farmers

    Agriculture makes up a major portion of Rwanda’s economy, and employs eight in 10 Rwandans. Of course, farmers are hugely dependent on the climate, and a new project hopes to ensure they get timely information so they can plan for both good times and bad.

  • The Technological World and the Risk of Nuclear Power

    The modern economy and our way of life depend on new and advancing technology. It especially depends on energy technology.

  • Slowly Moving to Protect the Environment

    In some cases we do not understand the impact of human actions on the planet and we need to do more observation and analysis to understand those impacts. In other cases we don’t really know how to repair the damage once it has been done.

    Helping Communities Respond to Climate Change

    A new tool helps scientists communicate better with communities on global climate change issues, increasing awareness and stakeholder engagement.

  • Optimism, But Also a Hard Bottom Line for Island States

    Optimism, But Also a Hard Bottom Line for Island States

    “Reaching an agreement would firstly mean an increase in awareness for the particular situation faced by small island developing states. States such as Kiribati are on the front line of climate change since they are already experiencing its effects, and an agreement would enhance recognition of [their] vulnerability.”

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
