Sir – The “climate change battalions” don’t waste time on the likes of the determinedly uninformed sceptic Michael Tyce (Letters, September 8).

He is so parochial that he equates Oxford weather with the planet’s climate.

Yes, our weather has indeed been unusual, precisely because of global warming, which has — among other things — displaced the jet-stream which so greatly influences British weather.

Professor Tyce could go and listen to the many scientists assembled in Oxford this month to debate the facts: but he wouldn’t like to hear those — he’s much happier in cloud-cuckoo land.
