Measures to conserve water where scarcity can be effected are always good. We've had the developing science of water resource management for centuries. What we have never had is a science of modifying weather so that we can get rain when and where we need it.

We had a seven year drought in Colorado during the 90s. There was plenty of water but it passed right over so that it could fall down and flood the Mississippi and Missouri rivers. Forest fires raged and crops in Colorado, Arizona, New Mexico, Utah withered while the crops in those river basins flooded out.

Currently and for the past couple of decades the US budget for research and development on this subject has 'dried up'. This seems stupid to me since major droughts or floods are so costly. We have a significant presence in the upper atmosphere and outer space for the first time in our history and this would seem to present some opportunities that were not available historically. For example, we could use satellites to spread a chemical film in outer space, which would cause a cooling shade over moist clouds. If you add that to what we already know about the microphysics of and dynamics of moisture systems we could potentially have some new technology, and it wouldn't take much to dissipate such a film so space pollution shouldn't be an issue ... climate change might be,

Surely we could at least consider some innovations given our new positions in space and the seriousness of the issue.
