John Brennan talks about Strategic Aerosol Injection.
“Another example of technologies is the one which is called geoengineering. These techniques can be used to alter global warming change. One method is called Strategical Aerosol Injection – SAI. SAI is a method of filling the atmosphere with particles that reflects the suns heat. Strategic Aerosol Injection can halt global temperature increases. It can also give nations some time to leave fossil fuels behind.
To reduce greenhouse effect has to be in connection with other things that has to do with climate changes, such as the oceans. Strategical Aerosol Injections by itself won’t be able to get rid of the greenhouse gases from the atmosphere. SAI is expensive and costs about 10 billion dollars yearly.
The techniques of geoengineering can alter the weather pattern at a geographical spot on behalf of another geographical spot. This could create protests from some people. Unfortunately we are missing norms and global rules to implement Strategic Aerosol Injection together with other methods of changing the climate.”
