As the coordinator for a think tank which happens to operate online, we do discuss geo-engineering. In other words ways, to change our climate, slowdown disastrous type storms, and create the average annual rainfall in the various regions on our planet which need it to survive. Of course, the ultimate goal would be to control the temperature of the oven that is to control the spherical flickering flame. Mankind will not be stuck in a cave looking at shadows on the wall forever, eventually his science will allow him outside the cage to discover and unlock the secrets of the universe.
If you've been following CERN lately, you can see we are about to do that with the foundations of particle physics with the Higgs Boson, or God particle; a good step in the right direction if mankind is grown-up enough to use this information to his advantage for the proper purposes. I assume that mankind is now responsible enough to keep these scientific facts outside the realm of maladapted humans, two-bit dictators, and scientifically endowed international terrorists.
It probably is a good thing that humans cannot control the Sun currently, because they might turn it down to prevent global warming, based on erroneous data and perhaps slipping us into an Ice Age. Since everything in our universe affects everything else, the only question is to what degree, we have to be cognizant of the fact that when we start screwing around with such a very complex system, we had better know what we're doing, otherwise we will be playing Russian Roulette as we play games with our Sun, the Earth's atmosphere, and work to exploit all of our geo-engineering technology and abilities.
