Alma Mater’s Other Secret: a Way Forward on Climate
Sitting on the iconic front steps of Low Library, Alma Mater rests on a plinth that offers a clue to a possible method of carbon sequestration, a vital technology for addressing our problem of too much CO2.

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…

The Advances and Challenges of Carbon Capture and Storage
While in energy policy discussions, I heard carbon capture, utilization and storage consistently dismissed as either too expensive or too uncertain in a low-carbon future that favors natural gas, energy efficiency and renewable energy. Yet as was made clear during the three-day Research Coordination Network on Carbon Capture, Utilization and Storage annual meeting hosted by…

From Theory to Reality: Closing the Carbon Loop
Carbon capture, storage and reuse has the potential to help us reduce CO2 emissions and combat global warming. The Lenfest Center for Sustainable Energy is bringing together experts from an array of fields to assess the state of the technology April 14-16.

Researcher Takes Measure of Carbon Storage in Iceland
The idea of capturing carbon and storing it away offers an appealing solution to the “greenhouse gas” emissions from fossil fuels that are warming the planet. But how can we measure the process well enough to know what sort of impact the technology has?

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…
