Thanks for the compliment. And yeah, I kind of wondered if you were serious about the "breathing" issue. Trust me, there are people out there who would actually buy that.
I don't accept the "monetary tradeoff" line of reasoning. It's really just a red herring to say "let's ignore every problem that we don't understand as well as this other problem over here." What you are really saying with that argument is that you have decided to discount this issue, without yet really understanding it.
Keep in mind that the current US administration has been reducing funding to research in these areas (and indeed, for environmental protection initiatives in general), and has also been monkeying with the consensus research reports before they come out. In my view, there are clearly political agendas getting in the way of the science - perhaps because of pressure from the petroleum industry? So it's not just a matter of choosing where to put your resources based on potential benefits - it's also about politics and money. That really bothers me.
Cutbacks on fossil fuel use are not the only solutions, anyway. What about CO2 reclamation technologies? How about reducing CO2 emissions from the production of refined fossil fuels? The best estimates I have seen also indicate that reforestation has a significant role to play in reducing atmospheric CO2 over the long term.
Yeah, we have limited resources avaialble to pursue all of these things, but redirecting all the money spent on climate change research to cancer research isn't necessarily going to solve that problem either, and I don't think we can really afford to ignore either. I guess my appeal is just to try to get the politics out of it (on both sides - the radical greenies are over the top too) and let the scientists do their jobs. What we don't need is another politically and economically motivated "scientific review" of the subject from some group like the Fraser Institute.
Like it or not, the current scientific consensus is that increasing global CO2 is a profound change, and it is largely man-made. Because of the potential for long term adverse effects, that same community of scientists advocates taking action to address the problem. Exactly what that action should be is a political issue, but as a citizen I don't support the "do nothing on this because we have bigger problems to deal with" position. PM Harper doesn't either, as far as I can tell.
