Researchers Develop an Artificial Intelligence to Analyze Birdsong in a Warming Arctic
A new algorithm quickly sifts through hours of field recordings to learn how climate change influences bird migration. The A.I. could help track other wildlife as well.

Shrinking Ice Sheet Made A Surprising Comeback
Thousands of years ago, the West Antarctic ice sheet shrank dramatically—then grew back in an unexpected way.

Days on Earth Are Getting Longer. You Can Thank the Moon, Not the Seasons.
For anyone who has ever wished there were more hours in the day, geoscientists have some good news: Days on Earth are getting longer. Very slowly.

Increasing Heat Is Driving Off Clouds That Dampen California Wildfires
Sunny California may be getting too sunny. Increasing summer temperatures brought on by a combination of intensifying urbanization and warming climate are driving off once-common morning cloud cover in southern coastal areas of the state, leading to increased risk of wildfires.

Machine Listening for Earthquakes
In a new study, researchers show that machine learning algorithms can pick out different types of earthquakes from three years of data at Geysers in California. The repeating patterns of earthquakes appear to match the seasonal rise and fall of water-injection flows into the hot rocks below.

In India, Dirty Air Kills as Easily in the Country as in the City
A forthcoming study of northern India suggests that people living in rural areas are as likely to die prematurely from the effects of poor air quality as those living in cities.

In Ancient Rocks, Scientists See a Climate Cycle Working Across Deep Time
A gradual shift in Earth’s orbit that repeats every 405,000 years plays a role in natural climate swings.

The 100th Meridian, Where the Great Plains Begin, May Be Shifting
Two new papers find that the line that divides the moist East and arid West is edging eastward due to climate change—and the implications for farming and other pursuits could be huge.

Climate Migrants Will Soon Shift Populations of Many Countries, Says World Bank
If emissions of greenhouse gases remain high, as many as 143 million “internal migrants” might move within their own countries by 2050.

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
