Via MR, a really good NYT article written by John Tierny with a proposal that will put climate change skeptics and proponents beliefs to the test: tie the amount of carbon taxed/capped to the rise in temperature on earth. Why is this great? If skeptics are right, we don’t pay anything. If global warming proponents are right, we will have the safe guards installed to make sure that when temperatures do rise, we are able to internalize the actual cost of carbon, thereby limiting the amount we emit into the future.
Of course there will be needed discussion on just how the temperature should be measured, but the idea is foolproof nonetheless: the only judge of how much damage we are really doing to our earth will be from the earth itself. No arguing over fudged forecasts or ulterior motives, this plan would take all of the political risk out of future changes to the climate and create a more forward looking plan; a plan that everyone will now have a stake in, including private investors – if they want to make sure that they hedge against higher costs in the future.
The problem with politics now would be how to implement it. Cap and trade or carbon tax? The article suggests:
[…] it would be even better, Dr. McKitrick says, to use the temperature readings as the basis for a carbon tax instead of a cap-and-trade system. Like many economists and environmentalists, he argues that the carbon tax would be more effective at reducing emissions because it is simpler, more transparent, easier to enforce and less vulnerable to accounting tricks and political favoritism.
It is certainly true that a carbon tax would make things easier, but does it provide the efficiency that cap and trade would provide? One of the benefits of cap and trade is to allocate carbon credits to those who need to pollute the most, providing incentive for others to focus on creating more efficient and cleaner ways of lessening their carbon footprint. Just because a carbon tax may be easier, it still doesn’t yield the benefit of the gains from trade that could happen if carbon is able to be capped. In this case, only true polluters would bear the brunt of the costs, which could in turn, offset end costs to consumers. (Which is the driving point for cap and trade)
