Climate Change and the Complexity of Science
The diplomatic debate about phasing out HFCs has been underway for seven years, but the technology of refrigerant coolants appears to have finally caught up with the need for replacement technology. Once replacement technology is available, diplomacy becomes possible.

For Climate Change, Carbon Pricing is No Silver Bullet
Many economists and policy experts believe carbon pricing is the most effective way to deal with global warming. But others argue that carbon pricing is not a silver bullet for dealing with climate change. Here’s why.

Study Warns of Surge in Heat-Related Deaths in New York City
A new study projects that as many as 3,331 people a year could be dying from the heat during New York City summers by 2080 as a result of the warming climate. That compares to 638 heat-related deaths on average between 2000 and 2006.

Wind-Blown Antarctic Sea Ice Helps Drive Ocean Circulation
Antarctic sea ice is constantly on the move as powerful winds blow it away from the coast and out toward the open ocean. A new study shows how that ice migration may be more important for the global ocean circulation than anyone realized.

Carbon Pricing for the Climate: How It Could Work
Most economists and policy experts agree that the most effective and cheapest way to curb the carbon dioxide emissions that are warming the planet is to “put a price on carbon.” How effective are carbon taxes and cap and trade programs?

Preparing for Climate-Related Food Shocks
Researchers are investigating if the projected increase in climate change-generated droughts, floods, heat waves and other intense short-term occurrences will result in increased shocks that could jeopardize food security worldwide.
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
