Sensitivity of ocean acidification to geoengineered climate stabilization

H. Damon Matthews, Long Cao, Ken Caldeira

Abstract

[1] Climate engineering has been proposed as a possible response to
anthropogenic climate change. While climate engineering may be able to
stabilize temperatures, it is generally assumed that this will not prevent
continued ocean acidification. However, due to the strong coupling between
climate and the carbon cycle, climate engineering could indirectly affect
ocean chemistry. We used a global Earth-system model to investigate how
climate engineering may affect surface ocean pH and the degree of aragonite
saturation. Climate engineering could significantly re-distribute carbon
emissions among atmosphere, land and ocean reservoirs. This could slow pH
decreases somewhat relative to the non-engineered case, but would not
affect the level of aragonite saturation due to opposing responses of pH
and aragonite saturation to temperature change. However, these effects are
dependent on enhanced carbon accumulation in the land biosphere; without
this, climate engineering has little effect on pH, and leads to accelerated
declines in aragonite saturation.
