The cost projections Lomborg uses represent one set of estimates, but far more favorable ones exist, too. Given that the additional antiwarming steps that might be taken arent yet knownand so their net costs are impossible to stateit is premature to dismiss them as phenomenally more expensive.So, tell us what those steps are, then, and how much they will cost
What would you think of this sales pitch: You really know you need a car, and the car salesperson comes up and says "We're not going to tell you how much this is until you sign on the dotted line and agree to pay us whatever we ask."
This appears to be what the Scientific American editor wants, and only a complete idiot would agree to it.
