For instance, what is the usual response of a CAGW movement supporter to learning that, under their own climate sensitivity assumptions, other forms of geoengineering than CO2 cutbacks could neutralize the predicted warming for <
= ~ 1 % the cost and with
lesser biological side - effects (such as stratospheric dispersion of micron - scale reflective
dust staying suspended for months at appropriate altitude, in radiative forcing neutralizing orders of magnitude more than its own mass in CO2)?
