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.

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?

Queue Dawlish!

Amazing.
So no global warming, then?

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
