Carbon Sampling Takes Flight

Last month, aerial photographer and biologist Matevž Lenarčič flew a single-seat airplane across 2000 kilometers of airspace between Easter Island and Totegegie Airport in French Polynesia (right). That lonesome leg was one hop on a 3-month journey around the world, during which Lenarčič and his tiny, lightweight aircraft, a Pipistrel Virus (inset), also touched down on Antarctica, a rare solo feat. Between piloting the plane and collecting photographs for an upcoming book on water, Lenarčič has also collected data on black carbon, or soot, concentrations in the atmosphere. His 290-kilogram plane carries a much-lighter-than-normal Aethalometer, designed by aerosol scientist Griša Močnik of Aerosol in Ljubljana, Slovenia, that measures the optical absorption of the atmosphere and converts it to a rough estimate of soot concentration.

Synthetic Stones Capture Carbon

While scrubbers in smokestacks at coal plants can pull out toxic gases like sulfur dioxide, scientists haven’t yet developed a cost-effective technology to remove carbon dioxide from industrial exhaust. Now European researchers have tinkered with the chemical composition of limestone to produce a material that absorbs almost twice as much CO2 as the natural mineral can (Environ. Sci. Technol., DOI: 10.1021/es2034697).
