This post is intended to raise three questions.
A few months ago Paul Homewood wrote an interesting post on a possible link between UK sunshine, temperatures and air pollution. Because of our recent sunny weather, and long may it continue to warm my old bones, the issue is worth raising again.
Here we have a normalized graph of UK sunshine and temperature from 1929 based on data I recently downloaded from the Met Office. Obvious questions are :-
Is a link between UK sunshine and temperature worth pursuing?
Could air quality be a factor?
Do activists distort our perception of pollution?
