The BBC using The Archers to propagandise on behalf of 'global warming'

From tomight's Archers, right at the end. You can listen to this on the BBC iPlayer.

Jennifer Aldridge - "Kate was saying only this morning that she's sure that  global warming must have a lot to do with it."

David Archer - "She could be right"

Jim Lloyd - "Well, it's common knowledge there's been a marked increase in the incidence of extreme weather"

Jennifer Aldridge - "And that's all around the world"

Is that common knowledge? Is it correct?

Here's some facts  that Jim 'Professor' Lloyd should really take notice of before he opens his faux intellectual mouth to opine on this subject again. Maybe he should stick to the Classics.
