Cloud Geoengineering Story

At night only the infrared Especially as there will be more Some clouds however are good Clouds reflect sunlight, but also absorb infrared energy. absorbtion continues. This clouds in a warmer world... for the climate. 'Extra white clouds' for instance. means most clouds are actually 'bad for the climate'. This feedback may double the world's CO, warming! O 00 BOS BOS But if the spray of droplets (containing salt aerosols) is too fine, these may compete with aerosols in existing clouds and And if the droplets are too heavy, they won't reach the clouds. Just one to two percent Clouds are whiter if the water This led John Latham to the idea droplets in them are smaller. Which happens when there are more condensation particles or of 'cloud whitening', by trying to increase the number of aerosols inside clouds over parts of the ocean, by using sea water spray. of aerosols may have effect. Cloud seeding is delicate... aerosols in the cloud. clear the skies! © www.bitsofscience.org
