Renewables are a better investment than carbon capture for tackling climate change

Who knew that shooting yourself in the foot was less harmful than shooting yourself in the head?~ctm Lancaster University Solar panels and wind turbines coupled with energy storage offer a better hope for tackling climate change than trying to capture carbon from fossil fuel power stations, according to new research published by Nature Energy. Carbon…

Scientists turn carbon emissions into usable energy

Public Release: 19-Jan-2019 Scientists turn carbon emissions into usable energy Ulsan National Institute of Science and Technology(UNIST) IMAGE: This is a schematic illustration of Hybrid Na-CO2 System and its reaction mechanism. view more Credit: UNIST A recent study, affiliated with UNIST has developed a system that produces electricity and hydrogen (H2) while eliminating carbon dioxide…

Simplest climate model yet – a bathtub

Climate change: How could artificial photosynthesis contribute to limiting global warming? Scientists calculate areas needed for forestation and artificial photosynthesis After several years during which global emissions at least stagnated, they rose again somewhat in 2017 and 2018. Germany has also clearly missed its climate targets. In order to keep global warming below 2 degrees…

Climate warming experiment finds unexpected results

From Phys.org January 4, 2019 by Emily Pontecorvo, American Geophysical Union Tropical forests store about a third of Earth’s carbon and about two-thirds of its above-ground biomass. Most climate change models predict that as the world warms, all of that biomass will decompose more quickly, which would send a lot more carbon dioxide into the…

Storage wars

From EurekAlert! UC Santa Barbara researcher conducts first-ever global-scale evaluation of the role of soil minerals in carbon storage University of California – Santa Barbara One answer to our greenhouse gas challenges may be right under our feet: Soil scientists Oliver Chadwick of UC Santa Barbara and Marc Kramer of Washington State University have found…

Six feet under, a new approach to global warming

From Eurekalert Public Release: 26-Nov-2018 WSU researcher sees how deep soil can hold much of the Earth’s carbon Washington State University VANCOUVER, Wash. -A Washington State University researcher has found that one-fourth of the carbon held by soil is bound to minerals as far as six feet below the surface. The discovery opens a new possibility…

System to rid space station of astronaut exhalations inspires Earth-based CO2 removal

From people who get grants, but may be thermodynamically challenged.~ctm November 13, 2018 by Anthony King, From Horizon Magazine When astronauts aboard the International Space Station (ISS) exhale carbon dioxide (CO2), it’s removed from the air and pumped into space. Could an Earth-based version help remove greenhouse gas emissions from our atmosphere? In order to…
