I haven't updated this for a while, and I know it only encourages
Dawlish but anyway, please see link below which shows the Yearly, 10
Year, 20 Year & 30 Year moving temperature averages for Central
England since 1970, based on the Central England Temperature (CET)
series published by the Met Office to December 2009.
http://hadobs.metoffice.com/hadcet/data/download.html

Green line = Yearly Average, currently +10.11°c,
Blue line = 10 Year Average, currently +10.36°c
Purple line = 20 Year Average, currently +10.23°c
Red line = 30 Year Average, currently +9.98°c

Points to note:

Green line, yearly average reached a current low point of +9.54°c in
February 2009, and is rising again.
Blue line, 10 year average reached a high point of +10.51°c in June
2007, and is slowly cooling.
Purple line, 20 year average reached a high point of +10.25c in
February 2009, and is slowly cooling.
Red line, 30 year average is obviously still rising, but for how much
longer?

Not a safe conclusion to draw from a possible short-term cooling. There
will always be such short-term fluctuations. Comparing the 10, 20 and 30
year averages quoted above strongly indicates GW over timescales of
greater than a year or two:

Blue line = 10 Year Average, currently +10.36°c
Purple line = 20 Year Average, currently +10.23°c
Red line = 30 Year Average, currently +9.98°c

There has without doubt been warming in Central England over the past
20 / 30 years but, as I have stated in the past, I'm still not
convinced that it is due to Anthropogenic Global Warming (AGM) and CO2
emissions.

Red line, 30 year average is obviously still rising, but for how much

Thanks for the data and graphs, interesting.

However, as a 'moderate' AGW sceptic, the first thing that jumps out
at me is that in the yearly (green line) averages, we are currently
near the lower end of a rising "channel" and unless the lower edge of
the channel is broken clearly, there is no reason for me to think that
over the next 10 years, it won't rise once again towards the upper
limit of the channel (currently around 11.6). I can see signs of a
reversal already.

If within 10 years the green line *hasn't* risen close to the upper
channel line, we can start to wonder if the longer term trend is under
threat. But for now, the channel, and hence the trend, is unbroken.

Thanks Dave,

I will try and remember to update the graph every 3 to 6 months, it
will be interesting to see where we are in a years time.

I know, I was being sarcastic

But it is just this kind of short term trend that the denialists
seize upon to try to prove it's not happening.
Just like the trend in the last couple of years for an increase
in arctic sea ice, albeit from the conveniently cherry-picked
extreme low of 2007.
