SIR – So, Keith Thomson has given up as a lost cause responding to my comments on climate change (Letters, April 23), but may I be allowed to apologise in quoting the wrong ‘ology’ he had graduated in.

However, he knows full well from my letter that did not alter one jot the reasoning of it, which boiled down to stating that so-called experts in all fields are often proved wrong and sometimes incompetent.

I will still read his weekly well-intentioned column.
