I wouldn't expect an effective response unless or until there is a mainstream estimate of the economic cost of climate change that would exceed the amount necessary to motivate action applied to the cost of energy. Are you aware of one? Like, I'm saying, (1) what is the price of energy that would reduce CO2 output enough to "effectively" address warming, and (2) what is the source that says the annual net cost of not addressing the climate in several decades is more than the yearly cost of killing demand at the price in (1)? This seems like a very important question no matter what you think the answer should be, because it would affect strategy for addressing climate change. Is effectively stopping climate change a matter of better accounting, or of changing what billions of people value and how much?
