The trouble the denialists face is planting your head in the sand and ignoring the facts, or being plain disingenuous, can give the socialists even more justification for their taxes and carbon credits when proved right. Rather then just fight the plain fact that human activity does indeed effect the climate, why not be a political force into what projects money and effort is channeled? Do you mean - "The trouble the denialists faces is that planting your head..."? Assuming you do - Well I don't think many would say that human activity clearly has no impact on climate. The questions and the issues where there is uncertainty are 1 - Exactly how much of an effect does it have? 2 - How large is this effect compared to natural causes/changes, some cyclic, some not, some fairly well understood, some not so well understood? 3 - How much do different human activities lead to global warming and cooling, and how much could new activities or expansion of old ones lead to warming or cooling? Assuming we on the net contribute a warming effect, could we do something that would provide a cooling effect to counteract this warming effect. 4 - How linear is the direct warming effect from our emitting CO2 or other greenhouse gases? 5 - How linear is the indirect effect or feedback caused by our CO2 emissions. What other factors are casued by more CO2, or more probably a warmer atmosphere that contribute to or counteract warming? 6 - How will the absorption of CO2 in natural sinks change going forward? 7 - If we are getting warmer from human emission of CO2 what's effect will it have? (Consider both positive and negative effects) 8 - What should we do about to prevent, counter act, and/or adjust to the warmer temperatures?
