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 – TMax Cooling at -1C / decade for last 5 years
UK Met data shows that UK Daily Tmax (mean maximum temperature) is cooling at at -1.088C / decade for the last 5 years.

UK May Tmax temperatures cooling at -.618C / decade for 15 years
Using data from the UK Met, May Tmax (mean maximum temperature) in the UK is cooling at -.618C / decade for 15 years.
The warmest May Tmax (in the last 104 years) was 16.9C in 1992. May 2013 was 13.8C. Tied for 33rd coldest out of 104.
CO2 seems to not work in May in the UK ….
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.
