Cloud-Seeding Ships Could Combat Climate Change
 









Excerpts:     Artist's impression of a Flettner spray vessel. The wind would be
blowing from the right-hand side of the image, the rotor spin would be clockwise
as seen from above, and the rotors would push the vessel to the left. (Courtesy:
J. MacNeill)    It should be possible to counteract the global warming
associated with a doubling of carbon dioxide levels by enhancing the
reflectivity of low-lying clouds above the oceans, (...) this can be done using
a worldwide fleet of autonomous ships spraying salt water into the air.  Clouds
are a key component of the Earth's climate system. They can both heat the planet
by trapping the longer-wavelength radiation given off from the Earth's surface
and cool it by reflecting incoming shorter wavelength radiation back into space.
The greater weight of the second mechanism means that, on balance, clouds have a
cooling effect.
