Where’s the warming? And BTW, the 2°C is not science based.
The Economist editorializes:
Winston Churchill famously said America would always do the right thing after exhausting the alternatives. The right thing in climate policy for all the big countries is a carbon tax, which is simpler and less vulnerable to fluctuations in emissions than cap-and-trade schemes. For years, such a tax has been a non-starter politically. But as the alternatives are tested to destruction, it deserves to be looked at again. Current environmental policies will not keep the rise in global temperatures to below 2°C—the maximum that most climate scientists think safe. A carbon tax, if stiff enough, could. Big polluters should assume that such a tax will one day arrive, and start planning for it now.
