Al Jazeera America–Can carbon dioxide removal save the planet?

Imagine 10 million car-sized contraptions dotted along shorelines and scattered throughout open spaces, sucking carbon dioxide from the air, powered by vast amounts of electricity and water. Or immense complexes for pulverizing and dumping limestone into the oceans at rates near the current use of coal. Or arable land devoted to growing biofuel rather than […]

Al Jazeera America—If the world had a giant thermostat, who would control the weather?

As the prospect of a warmer planet becomes reality, scientists are seeking ways to control the climate and keep the planet cooler. It’s a risky and highly controversial idea and, if successful, could imperil the ozone layer and lead to changes in rainfall patterns worldwide. It could also pit nations against one another as they […]

Al Jazeera America—Scientists threatened by demands to share data

When Christopher Lortie was earning his Ph.D. in ecology at the University of British Columbia in the late 1990s, he joined a small consortium of international ecologists who pooled their resources to study the potential effects of climate change on alpine-plant communities around the world. He spent several months trudging up and down mountains in […]


The New York Times—Seeking to Help Budding Researchers With a Click of the Mouse

An estimated 1.5 billion people worldwide live without dependable electric power. In places like Kenya, lead-acid batteries are affixed to bare wires and used to charge cellphones, radios and lights. By collecting baseline data on how these batteries are used, the two researchers hope to show that an improved battery system can hasten rural electrification. […]


Archaeology—The Subatomic Dig

How a particle accelerator in France has revolutionized artifact analysis. Some of the greatest discoveries in the future of archaeology may lie within the molecules of excavated artifacts. Thanks to the extremely powerful X-ray beams produced by a type of particle accelerator called a synchrotron, scientists can now look within artifacts at an unprecedented degree […]


The Christian Science Monitor—How to stash carbon dioxide: Turn it into stone.

A long-known but little-tested means of permanently storing carbon dioxide (CO2) underground, mineral carbonation, is now the subject of study in Iceland and Oman. The good news is that mineral carbonation promises to lock away CO2 – a powerful greenhouse gas – in a much more stable form than simply pumping it into an underground […]
