Cooling the tropics more than the poles is also a choice for stratospheric aerosol injection; if you want that effect you can presumably do that, and if you’d rather cool the poles more than the tropics you could do that instead. From: geoengineering@googlegroups.com

Hi All Alexander Robinson writes that most geoengineering methods will cool the tropics more than the poles. This might be true for stratospheric sulphur because of its long lasting effects spreading everywhere in the same hemisphere. But it is difficult to see how this could happen if

Hi Stephen, With stratospheric aerosols, you don’t get longitudinal control (it is well mixed longitudinally), and you don’t get the rapid temporal response that you can achieve with MCB, but you still have some degree of latitudinal control. If you inject far enough north of the equator,
