Current practice is to grind and burn enormous amounts of limestone, releasing equally enormous amounts of CO2 to the atmosphere. But isn’t there some way to reverse the chemical process and still end up with building material?
Geoengineering can be compared to taking a pill for being overweight. Instead of trying to tackle the root of the problem, it tries to cure the symptoms. But like medicine for reducing obesity we will probably need it in the … Continue reading
An international team of researchers today in Nature explain the importance of dust storms for climate variability, not just for the radiative balance, but also for the Earth’s carbon cycle. For geoengineering minds: iron fertilisation at least seems to have … Continue reading
Breeding crops with deeper (and larger) root systems could help to lower atmospheric CO2 levels, while also making the crops better drought-resistant, Douglas Kell, a Professor of Bioanalytical Science at the University of Manchester says.
Chemists of Lehigh University have engineered new porous materials to adsorb [adhesion of gas to surface] both CO2 and methane from flue gas.
Ocean iron fertilisation, one of the most discussed CDR geoengineering proposals, deliberately tries to stimulate biological activity in the upper ocean. New research shows this in turn affects ecology at the ocean floor too. Let’s just hope sea cucumbers don’t … Continue reading
