Reply to Patrick Brown’s response to my article commenting on his Nature paper

Introduction I thank Patrick Brown for his detailed response (also here) to statistical issues that I raised in my critique “Brown and Caldeira: A closer look shows global warming will not be greater than we thought” of his and Ken Caldeira’s recent paper (BC17).[1] The provision of more detailed information than was given in BC17, and […]

Brown and Caldeira: A closer look shows global warming will not be greater than we thought

A guest post by Nic Lewis Introduction Last week a paper predicting greater than expected global warming, by scientists Patrick Brown and Ken Caldeira, was published by Nature.[1]  The paper (henceforth referred to as BC17) says in its abstract: “Across-model relationships between currently observable attributes of the climate system and the simulated magnitude of future […]

Shoveling into the wind: Blizzards and global warming

In fact, warming theory suggests that you’d see […]

This Gets Even More Amusing

Can anyone on the Team actually hit a target? A couple of days ago, I reported that Santer’s own method yielded failed t-tests on UAH when data up to 2008 (or even 2007) was used. I also reported that their SI (carried out in 2008) included a sensitivity test on their H1 hypothesis up to […]
