    Shareholders Turn Up the Heat on Climate Change

    2016 was a hot year for climate change shareholder resolutions hitting the boardrooms of oil and gas companies. Although more familiar climate news headlines have carried calls to “keep it in the ground” and divest investment portfolios from fossil fuels, a patient strategy has been quietly gaining momentum: shareholder engagement on climate change.

  • Protecting Indigenous Land Rights Makes Good Economic Sense

    Protecting Indigenous Land Rights Makes Good Economic Sense

    Indigenous peoples and other communities hold and manage 50 to 65 percent of the world’s land, yet governments recognize only 10 percent as legally belonging to these groups, with another 8 percent designated by governments for communities. That’s bad economic policy.

  • Trade Deals and the Paris Climate Agreement

    Trade Deals and the Paris Climate Agreement

    With the approval of the Paris Climate Agreement comes a key question: Do our trade and investment agreements—current and proposed—create the space, send the right signals, and clear the path for the U.S. and other countries to meet their Paris commitments?

  • Rising Temperatures Load the Dice for Megadrought Risk

    Rising Temperatures Load the Dice for Megadrought Risk

    As the American Southwest grows hotter, the risk of severe, long-lasting megadroughts rises, passing 90 percent this century if greenhouse gas emissions continue at their current pace, a new study from scientists at Lamont-Doherty Earth Observatory says. Aggressively reducing emissions can cut that risk.

    Pressure Mounts for Developing Countries to Leave Fossil Fuels in the Ground

    Calls are intensifying to phase out fossil fuels, and that is now beginning to occur in many developed countries. This shift will have profound implications for the developing world, which has vast untapped fossil fuel resources, but may be unable to realize their value.

    Land, Resource Investments and Climate Change: 3 Key Takeaways

    Any discussion on climate change and sustainable investment in natural resources must grapple with land—a complicated yet crucial component of the search for equitable climate change solutions.

    Flaring Gas: How Not to Waste a Valuable Resource

    Every year, oil fields around the globe burn, or “flare,” an estimated 3.5 percent of the world’s natural gas supply. The gas is produced alongside oil and must be disposed of during the production process. Eliminating flaring would reduce CO2 emissions by as much as removing 77 million cars from the road. Moreover, the flaring…

    Facing Rapid Change in the Arctic

    An expedition to the Canadian Arctic and west coast of Greenland is a moving and motivating experience for Lamont-Doherty Earth Observatory climate scientist Maureen Raymo.

    An Ecological Traffic Jam in the Warming Tropics?

    The tropics are already hot, and they’re getting hotter as global temperatures rise. A new study offers a glimpse into how seriously a couple more degrees could disrupt the region’s ecological map.

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
