I haven't commented on this issue in a good long time. I also haven't really been paying much attention to it lately as the foolish carbon tax idea was abandoned in my country and seems to be a dead issue at the moment. That pleases me.
There hasn't been any statistically significant warming in something like 15 or 16 years. If anything this current solar cycle has been unusually weak and there has been speculation that we could see an extended solar minimum coming in the next few decades. Doesn't matter what us puny humans are doing if the sun weakens, our planet will cool, possibly even throwing us into the next glacial period.
For anybody worried about CO2, please keep in mind that CO2 levels exceeded 7,000ppm during the Cambrian period, and was fairly high at later periods as well. The planet and life on it did very well at these times, thriving, so no worries about the planet burning up. Our current CO2 level is barely flirting with 400ppm. Personally, I'm hoping to see 1,000ppm in my lifetime, since it's what plants crave. That level of atmospheric CO2 will double to triple our agriculture output too, which we may need as we add billions more people to our population.

Best course of action is to do nothing. There isn't a problem. And if global climate ever becomes a real problem I will tell you what will happen, for I have seen the future... I don't expect anybody to believe me, but I will tell you anyway...
Let me start off by stating that we spend some billions of dollars on global warming research every year. It's become a vast industry, involving politics, academics, scientists and business interests that are all heavy invested in it. This level of spending has been going on for a good number of years, wasting tens of billions of dollars up to this point already.
Now, at some point in the next 100 years, people will stop researching and start spending that money actually doing something. A real solution will emerge. Eventually, we humans will build machines that will completely control the earth's climate. The economic and military rewards of such a system make it an inevitability. It would probably cost in excess of 500 billion dollars to get a basic system in place. I would speculate that some kind of mirrored nano-material that could be unfurled in space like sails be used to either reflect sunlight away from the planet, cooling it, or reflect sunlight towards the planet, warming it. With a large enough satellite array of this type, it would be fairly simple to control not only the earth's global temperature, but also to alter the energy of storm systems as well as change storm paths. For less than the cost of some recent wars, my nation alone could have funded such a project. If a dire threat were truly to face the earth, I have no doubt the resources of many nations would be pooled and action would be taken.
So, again I say the best course of action is to do nothing. Unless maybe you want to study engineering and help build such a system one day.
