If we are declaring that we have the technology to change the planet's
thermostat, we soon get into an argument regarding what the temperature
should be, and how to decide.  This leads to some wildly complications, such
as what if one part of the planet is too cold and getting colder, while
another is too warm and getting warmer.  What about wet/dry places, and the
storm cycles?  Oy.
