From J. Bernard Sunderland:

Re: Scientists: artificial steps against global warming may be dan (Sept. 2): To this armchair scientist, it would seem to be the height of folly to intitiate solar energy control whilst continuing to extract fossil fuels, particularly because it will gloss over the significance of that latter activity as being the root cause of rising carbon dioxide level. Removal of carbon dioxide from the atmosphere appears logical but should be linked with cessation of fossil fuel extraction. I have a theory which I have seen to be valid so many times: that you can initiate any change you wish and change will occur, but not the change you wanted.
