Does anyone think that putting up a film between then Earth and the Sun is a solid solution to global warming?

recently a report on NPR mentioned that a researcher at the University of Arizona is working on the feasibility of puting a screen between the Earth and the Sun to shade the Earth and prevent global warming. i think this is the wrong approach because this solution does not address the cause of global warming. lets say that in this project is undertaken and succeeds some 50 years from now, would people care to reduce carbon dioxide emissions? it just seems like this solution is the path of least resistance. by the way, NASA has decided to fund this research. I have included a link that revealsmore about this project a href="http://www.sciencedaily.com/releases/2006/11/061104090409.htm" rel="nofollow"http://www.sciencedaily.com/releases/200…/a
