John Gibbons is having a go at Bjorn Lomborg. Mr Gibbons argues that Lomborg has a PhD in spin, while in fact he has a PhD in political science. Gibbons oddly suggests that Lomborg is behind “climategate”, and refers to economic models as “voodoo”. Most seriously, Gibbons suggests that statisticians and economists have no relevant expertise on climate science and policy.
Climate is defined as the 30 year average weather. Statistics is therefore at the core of climate science.
Greenhouse gas emissions are caused by economic activity. Emission reduction already costs a heap of money, will cost a lot more in the future, and would cost a whole lot more if economists do not help design abatement policies. Economics is therefore at the core of climate policy.
