    • Geoengineering refers to engineering aimed at counteracting the undesired side effects of other human activities (11). Two classes may be distinguished: climate engineering (12-15) and carbon cycle engineering [for example, through modifying ocean alkalinity (16, 17)]. Here, the word geoengineering refers specifically to climate engineering (i.e., direct and intentional management of the climate system).

    • MAGICC is a suitable tool because it reproduces the results from more complex coupled ocean/atmosphere general circulation models for both volcanic time-scale (21) and long-term (26) forcing.

    • 2O, halocarbons, and tropospheric aerosols). Emissions from these sources are assumed to follow the A1B scenario to 2100 and then remain constant, leading to a slow but long-term increase in radiative forcing.

    • Teller et al. (34) point out that sulfate aerosols are "grossly nonoptimized" as scatterers of short-wave radiation and that metallic or resonant scatterers offer large mass savings. Although emplacement costs for such scatterers would be higher, they estimate net costs (for metals) to be "as much as five times less" than for sulfate aerosols.

    • At steady-state conditions, an injection of 5 TgS/year into the stratosphere would increase the flux into the troposphere by the same amount, with larger fluxes in high latitudes. Given current emissions, the consequences of this extra flux are likely to be minor, but this aspect warrants further attention.
