Dear Ken,
in the article you stated that Mt Pinatubo is assumed to result in a
global cooling of about 0.5 degree. It is also stated in the text of the
article that the amount of aerosols emitted, if they would stay in the
stratosphere for a longer time period, would result in a 3 degrees
global cooling. Could you point me to the study you are referring to
that calculates this amount of cooling if injecting volcanic aerosols of
the amount of Mt Pinatubo?
Cheers, Simone
Ken
It should follow from your argument about the land-sea temperature
difference reducing precipitation on land that a technique which had the
initial effect of cooling the sea would be more attractive. If it were
also possible to have a frequency response shorter than the monsoon
cycle we could play useful tricks about the phase of operations relative
to the monsoon season.
