yes i wonder how many people read the full article and/or the full recommendations presented to Obama. in which this idea was the "last resort" idea. It was stated that they hopefully never intend to come close to utilizing this idea. As they stated themselves there are many unforeseen consequences. But i guess people who want something to complain about are going to read it however they want.
P.S More detailed articles about this, state they are looking at attempting to mimic a volcanic eruption without the ash and destruction surround it. Which BTW does effectively block out the sun's rays and does cool down the earth. but again, its not their first or even close to first choice. They just stated they want to have every opinion/option to be looked at and nothing discarded.
