AbstractProjected increases in greenhouse gases have prompted serious discussion on geoengineering the climate system to counteract global climate change. Cloud albedo enhancement has been proposed as a feasible geoengineering approach, but previous research suggests undesirable consequences of globally uniform cloud brightening. The present study uses GFDL’s Climate Model version 2G (CM2G) global coupled model to simulate cloud albedo enhancement via increases in cloud condensation nuclei (CCN…

Abstract. A simple heuristic model is described to assess the potential for increasing solar reflection by augmenting the aerosol population below marine low clouds, which nominally leads to
Defining success and limits of field experiments to test geoengineering by marine cloud brightening
Marine cloud brightening (MCB) has been suggested as a possible solar radiation management approach to geoengineering the Earth’s climate in order to offset anthropogenic global warming. We discuss
CLIMATE ENGINEERING : WHICH ROLE FOR SPACE ?
Global efforts made by the international community to reduce anthropogenic greenhouse gas emissions have not been successful yet to adequately address the challenge posed by climate change. On the

TLDR
There would be no justification for deployment of MCB unless it was clearly established that no significant adverse consequences would result, and there would also need to be an international agreement firmly in favour of such action.

TLDR
It is concluded that controlled global cooling sufficient to balance global warming resulting from increasing atmospheric CO2 concentrations might be achieved by seeding low-level, extensive maritime clouds with seawater particles that act as cloud condensation nuclei, thereby activating new droplets and increasing cloud albedo.

An observational study of diurnal variations of marine stratiform cloud
Abstract Marine stratiform clouds are important and highly variable contributors to earth's radiation budget over the eastern subtropical oceans and over middle- to high-latitude oceans in summer.
The impact of humidity above stratiform clouds on indirect aerosol climate forcing
TLDR
Simulation of stratocumulus clouds with a fluid dynamics model shows that the response of cloud water to suppression of precipitation from increased droplet concentrations is determined by a competition between moistening from decreased surface precipitation and drying from increased entrainment of overlying air.
