an unbelievable article on climate change from Bjorn Lomborg

Comments on Bjorn Lomborg “Emissions blame game has started”, 15/10/2009, http://www.theaustralian.news.com.au/story/0,25197,26210623-5013480,00.html

I can't believe the following by the author:

"Instead, the panel recommended focusing investment on research into climate engineering as a short-term response, and on non-carbon-based energy as a longer-term response.
Some suggested climate engineering technologies - in particular, marine cloud-whitening technology - could be cheap, fast, and effective. (Boats would spray seawater droplets into clouds above the oceans to make them reflect more sunlight back into space, reducing warming). Remarkably, the research says that a total of about $US9 billion spent implementing marine cloud-whitening technology might be able to offset this entire century's global warming. Even if one approaches this technology with concerns - as many of us do - we should aim to identify its limitations and risks sooner rather than later."

Is it believable that just $9 billion can do that much?
Using boats to spread sea water to reflect more sunlight can achieve that?
Is anyone who does this kind of research sane?
That simply defies the logic!When people are talking this kind of nonsense, it is no wonder why it is not easy to convince people on climate change.
