Deployment Strategy Shapes the Polar Climate Response to Marine Cloud Brightening
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.Abstract Marine cloud brightening (MCB) is a proposed solar climate intervention strategy that increases marine cloud reflectivity to cool Earth's surface. While previous studies have largely examined its global temperature and precipitation effects, little is known about how MCB deployment strategies influence polar climate and sea ice.

How marine cloud brightening could also affect stratospheric ozone. [PDF]
Sci AdvStratospheric ozone plays a crucial role in life and ecosystems on Earth, with a vast amount of research focused on the effects of human activities on ozone. Yet, impacts of tropospheric climate intervention methods like marine cloud brightening (MCB) have not previously been considered to reach the stratosphere.

The Radiative and Cloud Responses to Sea Salt Aerosol Engineering in GFDL Models
Geophysical Research Letters, 2023 Marine cloud brightening is a proposal to counteract global warming by increasing sea salt aerosol emissions. In theory, this increases the cloud droplet number concentration of subtropical marine stratocumulus decks, increasing cloud brightness and ...

Distinct regional meteorological influences on low-cloud albedo susceptibility over global marine stratocumulus regions [PDF]
Atmospheric Chemistry and Physics, 2023 Marine stratocumuli cool the Earth effectively due to their high reflectance of incoming solar radiation and persistent occurrence. The susceptibility of cloud albedo to droplet number concentration perturbations depends strongly on large-scale ...

Targeted marine cloud brightening weakens subsequent El Niño. [PDF]
Sci AdvExtreme events are often attributable to the compounding effects of anthropogenic warming and natural variability. Marine cloud brightening (MCB), a solar geoengineering proposal to reduce long-term warming, could theoretically mitigate extremes by instead targeting seasonal-to-multiyear phenomena, such as El Niño–Southern Oscillation (ENSO).

Cloud albedo changes in response to anthropogenic sulfate and non-sulfate aerosol forcings in CMIP5 models [PDF]
Atmospheric Chemistry and Physics, 2017 The effects of different aerosol types on cloud albedo are analysed using the linear relation between total albedo and cloud fraction found on a monthly mean scale in regions of subtropical marine stratocumulus clouds and the influence of simulated ...

Manipulating marine stratocumulus cloud amount and albedo: a process-modelling study of aerosol-cloud-precipitation interactions in response to injection of cloud condensation nuclei [PDF]
Atmospheric Chemistry and Physics, 2011 We use a cloud-system-resolving model to study marine-cloud brightening. We examine how injected aerosol particles that act as cloud condensation nuclei (CCN) are transported within the marine boundary layer and how the additional particles in clouds ...

Occurrence of lower cloud albedo in ship tracks [PDF]
Atmospheric Chemistry and Physics, 2012 The concept of geoengineering by marine cloud brightening is based on seeding marine stratocumulus clouds with sub-micrometer sea-salt particles to enhance the cloud droplet number concentration and cloud albedo, thereby producing a climate cooling ...
