A proposed geo-engineering technique that would see specially designed ships spray water into the air to seed clouds that would then reflect more of the sun's energy back into space.
Advocated by a number of scientists as a cost-effective means of curbing global temperature increases, the approach remains untested and has been criticised by some experts who fear geo-engineering techniques could have unknown and potentially dangerous side-effects on the world's climate.
Supporters of the idea argue that it represents fewer risks than alternative geo-engineering proposals as the ships can be stopped if they have unforeseen circumstances.
However, critics maintain that it is unlikely to prove effective and fails to address the ocean acidification that also results from increased atmospheric concentration of carbon dioxide.
