The Washington Post embarrasses itself today by publishing the usual delayer drivel in an op-ed by Bjorn Lomborg.

The fundamental problem with Lomborg’s argument (which he also makes in his recent book Cool It!) is that it is based on the assumption that the worst-case, climate-change scenario cannot happen.

The IPCC’s predictions for climate change over the next hundred years range from about 2°C to 5°C. If you assume that the warming will be closer to 2° than 5°, which Lomborg does, then it certainly does reduce the pressure to act immediately on climate change. No doubt about that.

However, there is no scientific basis for that assumption. Future warming certainly could be closer to 2°, but it could equally likely be close to 5°. We just don’t know.

Why does he make this assumption? Because there is a conclusion he wants to reach: We should not be taking action on climate change. The only way you can reach that conclusion is by assuming that future climate change will be mild.

This argument is bogus. Don’t believe it.
