Solving the Mysteries of Carbon Dioxide
About 50 percent of the CO2 produced by human activity remains in the atmosphere, warming the planet. But scientists don’t know where and how oceans and plants have absorbed the rest of the manmade CO2. To try to answer these questions, on July 2, 2014, NASA launched the $468 million Orbiting Carbon Observatory-2 (OCO-2), its…

Photo Essay: High Desert, Deep Earth
In the Arabian peninsula nation of Oman, geologists are studying the Hajar mountains–a range containing rocks that have been thrust up from the deep earth. Accessible to humans in only a few places on earth, these kinds of rocks offer clues to the planet’s deep history–and possible ways that natural processes may be harnessed to…

Ancient Rocks, Modern Purpose
The desert sultanate of Oman is home to some of the weirdest—and possibly most useful—rocks on earth. The stark Hajar mountains, near the border with Saudi Arabia, contain a chunk of earth’s mantle—a zone that makes up most of earth’s mass, but normally lies inaccessible to humans, far below the surface. Here, though, a sliver…

New Gift to Support the Launch of the Carbon Management Program
Following an initial gift last year to create a Masters Degree in Carbon Management, a generous Columbia University alumnus has renewed his support with additional funding toward the preparation and implementation of the program.

Understanding GHG emissions: Stock vs. Flows
In discussing climate change and greenhouse gas (GHG) emissions, a key distinction must be made between the stock of GHGs in the atmosphere, and the flow of GHGs, primarily emissions. Understanding this difference is crucial for designing and implementing policies to effectively address the problem. Because a bathtub is something that most of us are…

Can the Oceans Keep Mopping Up Carbon Dioxide?
The oceans absorb nearly a third of the carbon dioxide humans put into the air, and this has helped offset CO2’s potential to warm global temperatures. But many researchers think the oceans are struggling to keep pace with rising emissions. A new study looks at 30 years of data to see how natural variability and…

Yes, We Can Afford to Remove Carbon from Air
Recently, the American Physical Society (APS) released a report on the direct capture of carbon dioxide from air. The report concludes that air capture could be a powerful tool for mopping up carbon dioxide emissions that otherwise would escape to the air, for providing carbon dioxide for synthetic liquid fuels in the transportation sector, and…
