You might be interested in the paper ‘Impacts of stratospheric aerosol geoengineering strategy on Caribbean coral reefs’, just published online in the International Journal of Climate Change Strategies and Management, by Zhang, Jones and Crabbe. The abstract is: Purpose –Currently, negotiation on global carbon emissions reduction is very difficult owing to lack of international willingness. In response, geoengineering (climate engineering) strategies are proposed to artificially cool the planet. Meanwhile, as the harbor around one-third of all described marine species, coral reefs are the most sensitive ecosystem on the planet to climate change. However, until now, there is no quantitative assessment on the impacts of geoengineering on coral reefs. This study aims to model the impacts ofstratospheric aerosol geoengineering on coral reefs. Design/methodology/approach –The HadGEM2-ES climate model is used to model and evaluate the impacts ofstratospheric aerosol geoengineering on coral reefs. Findings –This study shows that (1) stratospheric aerosol geoengineering could significantly mitigate future coral bleaching throughout the Caribbean Sea; (2) Changes in downward solar irradiation, sea level rise and sea surface temperature caused by geoengineering implementation should have very little impacts on coral reefs; (3) Although geoengineering would prolong the return period of future hurricanes, this may still be too short to ensure coral recruitment and survival after hurricane damage. Originality/value –This is the first time internationally to quantitatively assess the impacts of geoengineering on coral reefs.
