Marine Cloud Brighteninghttps://youtu.be/o-0h14RFq4MStephen Salter is one of the leading voices of the Marine Cloud Brightening (MCB) movement.
As average global temperatures rise, increasing the reflectivity of clouds over the ocean has been studied as a geoengineering method to reflect more solar radiation away from the Earth thus reducing and reversing the warming caused by excess CO2 concentration in the atmosphere.
This CEF program was recorded at COP26, Glasgow, Scotland, in the Durdle Door press conference room on November 4th, 2021, and published on December 13th, 2021.

Topics discussed include the following:
- Why some clouds, such as cumulonimbus are dark, and some are light
- Using nozzles installed on ships to spray very small drops of filtered seawater 0.8 microns in diameter.
- Ships spraying filtered droplets of sea water could be deployed to reverse sea level rise and/or save the Arctic sea ice.
- Governments of countries could decide on targets for sea-surface temperatures
- Cost estimates to deploy a fleet of 800 spray vessels/ships
- Advantages of MCB as a geoengineering technique to prevent the worst extremes of climate change
- How we can change the reflectivity of clouds in areas that will most benefit the Earth.
