Washington Post: The suddenly urgent quest to remove carbon dioxide from the air

Relative comprehensive article on CDR. „From the rooftop of Klaus[nbsp]Lackner’s seven-story building on the Arizona State University campus, photovoltaic panels[nbsp]seem to glisten in every direction. The school claims to have more solar installed than[nbsp]any other university in America – part of a plan to offset the carbon emissions of this[nbsp]institution of more than 80,000 students.“

Physics Today: Nature spotlights deep skepticism about bioenergy with carbon capture and storage

„During the Paris climate summit late last year, European policy analyst Oliver Geden’s New York Times op-ed “The dubious carbon budget” warned that “we’re on the verge of repeating the same mistake that led to the financial crisis: relying on economic models that are completely detached from what’s going on in the real world.” With “magical thinking” and “questionable accounting,” Geden charged, climate scientists and economists are “betting primarily” on an unproven solution: BECCS, or bioenergy with carbon capture and storage.“

Cronkite News: Carbon-capture could ‘save the planet,’ ASU scientist says

„Steve Atkins, wearing khakis and a tucked button-down blue shirt, squints closely at a primitive unit set up on the roof of a research building on the Arizona State University campus in Tempe. The unit is about the size of a telephone booth. Two filters made of a resin material are placed above a see-through tank holding about 400 parts per million of carbon dioxide.“

The Conversation: To meet the Paris climate goals, do we need to engineer the climate?

„Our read is that the Paris agreement will, through time, force closer consideration of so-called “climate engineering” or “geoengineering” schemes. In particular, we foresee increasing attention being paid to solar radiation management (SRM) or albedo modification technologies. This is a class of speculative responses that might cool the planet by reflecting some amount of solar energy back into space before it can trapped by the greenhouse gases in the atmosphere. Leading SRM proposals include depositing reflective sulfate particles into the stratosphere or increasing the reflectivity of marine clouds via the introduction of saltwater droplets.“
