Sunny interval

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?

The trouble is that what is defined as pollution is only what is measured and what is looked for. If there have been a lot of things going on that are not perceived, measured or analysed then we will not know whether there is or is not a problem. My guess is that in the last half century and more so in the last couple of decades we have been putting a lot more stuff in the air than we realise.

Demetrius - there is a genuine problem with regulation here.

For example, regulators may list various pesticides for environmental monitoring, but this mandatory monitoring can crowd out the monitoring of newer pesticides.
