Bringing UK averages into the 21st Century - Met Office
29 August 2012 - The Met Office long-term UK climate averages have leapt forward a decade into the 21st Century to give the most up-to-date picture of our climate today, as well as an insight into how it has changed.
These 30-year averages are a standard way of assessing climate, providing a benchmark for a 'normal' month, season or year across all parts of the UK. They are updated as soon as possible after the end of each decade.
The 1981-2010 averages have just been released, adding to the existing 1971-2000 and 1961-1990 averages. In future the monthly, seasonal and annual climate summaries for the UK will use these new 1981-2010 records as the benchmark period.
Figures for 1981-2010 show that the UK's annual mean temperature is 8.84 °C, and that we get 1154 mm of rain and have 1373 hours of sunshine on average each year. By looking at how these values have changed compared to previous 30-year averages, we can see some interesting trends.
Higher temperatures consistent with global increases
Temperature shows the most marked change, with the UK annual mean temperature being 0.25 °C higher for the 1981-2010 period compared to 1971-2000, or 0.52 °C if compared to 1961-1990.
Comment to the Met Office:
Below is a chart for SunSpot activity for the past 300+ years.
Since the 1950's there has been an increase in solar activity at the same time we have seen an increase in World Temperature.
Maybe it's just coincidental, but an increase in solar activity since the 1950's could explain the increase in World Temperature and NOT "man made" co2!
It could be just the way I look at data, but maybe a far better way of adjusting the Met Office Standard is to make the past 50 years a reduction rather then an addition!
So, if the Met Office reduce their Standard by -0.70°C, they can then compensate for the extra solar activity for the past 50 years!
Using the new Standard (+0.25°C), anyone would think that "man made" co2 makes the world warmer instead of the Sun!
