I don't understand why these questions are so hard. If you have missed them thus far, they are:
1) Is there evidence of a steady rise in the Earth's temperature, say since the industrial revolution?
2) Is there proof that this rise is caused by human activity, and that nothing else could be the cause?
3) What are the steps we should take to stop or reverse this human-caused global warming?
4) How much will those steps cost, in terms of tax dollars spent, and lost opportunities, including lost opportunities for developing nations to grow and prosper, and for developed countries to innovate?
5) By how much will that proposed expendature reduce the Earth's temperature, and how do we know that?
If you cannot answer each of these questions, with evidence, not just guesses or links, then any policy you advocate based on "global warming" have no basis in evidence.
