Can marine cloud brightening reduce coral bleaching?

Cessation of MCB, particularly if atmospheric CO2 concentrations continue to rise, could result in very rapid warming, which for coral reefs is the most common condition leading to coral bleaching. The estimated annual cost of deploying MCB to inhibit coral bleaching around the major reefs is about ...

Effects of global warming on oceans
Global warming can affect sea levels, coastlines, ocean acidification, ocean currents, seawater, sea surface temperatures, tides, the sea floor, weather, and trigger several changes in ocean bio-geochemistry; all of these affect the functioning of a society.
