UK Met – Sunshine vs Tmax

In the UK, 2018 saw the 2nd highest sunshine hours since 1929  at 1580.7

If you graph the annual sunshine in the UK versus Annual Tmax …

Does CO2 affect sunshine? Or is something else going on?

Winter Rainfall UK 1910 to Jan 2014

Because of the floods, they are arguing about the amount of rainfall due to “climate change” over in the UK. Looking at the data from the UK Met for winter rainfall, it appears rainfall goes up and down.

I wonder if the usual AGW alarmist media blamed climate change for the dry period 2009 to 2011? Do I have to ask? Of course they did!

Guardian 17 November 2011: As well as the recent dry weather, water companies and environment regulators are expecting the UK to have more frequent dry winters as a result of climate change.

UK Decembers Tmax Cooling -.45C/decade for 30 years and Sunshine is Up Too

Using UK Met data from here, I noticed that Tmax for Decembers are cooling at -.45C / decade for 30 years.  Thats a lot!

And then I wondered why? A theme I have returned to over and over is that hours of bright sunshine has increased because of cleaner air. Could more sunshine in December lead to cooler Decembers since clear skies can lead to colder temperatures in winter?

Guess what. Sunshine is up an average of 5.5 hours per year in December for the last 30 years. And compared to 1988 sunshine is up 80% in December. Instead of 28 hours of sunshine in December, the average is closer to 48.
