How to cool the planet and save coral reefs by 2100: Experimental investigations of enhanced weathering as a geoengineering CO2 removal strategy
Rising CO2 levels pose increasingly severe risks to live on Earth – not just from global warming, but also due to secondary environmental effects like ocean acidification. From a purely ‘natural’ standpoint, anthropogenic changes to CO2 levels are effectively irreversible over human timescales, however, it may be possible to engineer reversibility through large-scale intervention in the climate system. One possible way to do this is to artificially enhance the silicate weathering rate by mining, crushing and distributing silicate-bearing rocks on land. This process could accelerate the removal of CO2 from the atmosphere, and would also release alkaline weathering products into the oceans, which could directly counteract ocean acidification.
Through a series of small-scale controlled experiments, my project will investigate the potential application of terrestrial enhanced weathering as a strategy for mitigating climate change.
