If that is the case (your background) you probably know more about the technical details than I do. I am just trying to get the basic understanding of the underlying mechanism to a degree where I know why my calculations make sense. My Feedback argument must look horrible simplified and I would probably had been going much more into details if I in fact knew your level of education (at least I hope it was useful for other members of this site).
Politics & Money or animal spirit as I am used to say (J. M. Keynes), is a never-ending motivation process for mankind. Unfortunately, corruption will always exist as long people have confidence in each other; at some point people will screw you because they can optimize their own utility.
I agree to some degree that "the end of the world" preaching might be a little overheated. I do not think we will die that easily, however, there are other major problems regarding consumption of fossil fuel; we will run out of fuel in a "short" period of time and it is very bad for people’s health. I think these two reason, simply, are enough to conclude; we need to do to something about it.
