NASA Finds New Way to Track Ozone By Satellite
Ozone pollution near Earth’s surface is one of the main ingredients of summertime smog. But it not directly measurable from space, due to the abundance of ozone higher in the atmosphere, which masks the surface. Now, researchers have devised a way to use satellite measurements of the precursor gases that contribute to ozone formation to…

National Climate Report: Q&A With Authors
Every four years Congress is provided with a state-of-the-art report on the impacts of climate change on the United States. The next National Climate Assessment is scheduled for 2018, but its scientific findings are scheduled to be published today. Here, two of its authors explain what to expect.

Settling in at McMurdo Station in Antarctica
Even though our tent is within a short drive of McMurdo (a small town with most of the safety and logistical equipment on the entire continent), we still need to prepare ourselves for sudden, extreme weather. Every time we leave the relative safety of McMurdo, we carry our Extreme Cold Weather equipment and our tent…

Giant Boulders on Bahamas Coast Are Evidence of Ancient Storms and Sea Level, Says Study
A new study says that storms of intensities seen today, combined with a few meters increase in sea level, were enough to transport coastal boulders weighing hundreds of tons more than 100,000 year ago.

By 2100, Climate Change Could Alter Key Microbial Interactions in the Ocean
The warmer, more acidic waters caused by climate change influence the behavior of tiny marine organisms essential to ocean health.

In Biblical Land, Searching for Droughts Past and Future
Human-influenced climate warming has already reduced rainfall and increased evaporation in the Mideast, worsening water shortages. Up to now, climate scientists had projected that rainfall could decline another 20 percent by 2100. But the Dead Sea cores suggest that things could become much worse, much faster.

Photo Essay: The Dead Sea, Living Waters and Megadrought
Thousands of years before Biblical times, during a period when temperatures were unusually high, the lands around the Dead Sea now occupied by Israel, Jordan and surrounding nations suffered megadroughts far worse than any recorded by humans. Warming climate now threatens to return such conditions to this already hard-pressed region.
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
