IPCC Corrects Claim Suggesting Climate Change Would Be Good for the Economy
The non existent economic benefits of climate warming will be enshrined in wingnut mythology now and forever due to a mistake in a 2009 paper, even though the IPCC is pulling the statement based on the flawed paper from the new report.
the first paper in the series, published in the Journal of Economic Perspectives in 2009, had contained a number of errors, including a claim that some other studies had found net positive impacts for warming of less than 3C. Unfortunately, Tol had not used the correct figures from these studies.
I discovered the errors after a draft of the IPCC chapter was leaked online in January, and I alerted Tol and the other authors of the report. The IPCC acknowledged the mistakes in the draft and agreed that the final version should not include them.
In May, the Journal of Economic Perspectives published an update and correction to Tol’s paper, in which he admitted the errors.
However, Tol’s 2009 paper had already been heavily promoted by climate change sceptics.
