On Dec 11th, the Economist published an unsigned article attacking both me and my work. This open letter is my reply.
TO: The Person Unwilling to Sign Their Economist Article
Dear Sir or Madam;
Recently, you wrote a scathing article about me in the Economist discussing my post called The Smoking Gun At Darwin Zero. Some of it was deserved, but most was undeserved and false. The URL for your unprinicpled attack is http://www.economist.com/blogs/democracyinamerica/2009/12/trust_scientists … trust_scientists? Trust_scientists?? Have you read the CRU emails?
So, to sum up your first arguments, changes in the Stevenson Screens and other local conditions cannot be the explanation for any of the GHCN adjustments because 1) the GHCN doesn’t use local conditions to make adjustments and 2) the timing of the screen change is wrong. In addition, there was no “dramatic change in 1941″.
Finally, the Economist did not contact me before publishing an article full of false accusations
