Hi,

I am very interested in the recent discussion regarding the warm autumn. It is true it was the warmest since records began in Central  England since 17th Century. However, caution has to be applied. Why ? Because the previous warmest autumn was 1730 and 1731 ( yes they do cluster ) which was during the Little Ice Age in Europe...and it was followed by 1740 one of the coldest years on record. Like they say one swallow doesn't make a summer, therefore I record season does imply climate change. Its a common mistake !

However, I do accept that it is part of the evidence that the climate is changing, and that the evidence comes from the ocean in sea surface temperature and heat storage. ( See our paper in Geophysical Research Letters last week ).

I have been worrying about this for a while - just what my own sense experiences of the world are telling me about the current weather. Never have the wintry images of Christmas seemed so at odds with reality on the ground.
 
This reinforces the idea that the only problem with current climate models is their failure to predict the rapidity of change. But still barely a murmur in media land, except for a few clothes retailers bemoaning a drop in profits due to slow uptake of their winter fashions.
 
How worried should one be? When is it okay to start panicking?

Subject: UK AUTUMN HOTTEST ON RECORD BY LONG STRETCH


Dear all



below is the official Met office anouncement. I take from it three very worrying facts:

a) Autumn 2006 has been the warmest ever recorded in the UK. We can assume that it is also the hottest autumn for a very very long time.

b) For England it is a full ONE DEGREE hotter than the previoous highest record. One degree is a great deal in climate terms, especially given that this should be at the outer extremes of improbability. It is like someone running a mile in 2 minutes.

c) the previous hottest autums was last year. This means that in one year the English autumn has gone one full degree higher than the previously hottest autumn ever recorded.

I find the rapidity and especially the scale of these differences extremely disturbing.

Yours

George

Warmest autumn on record - confirmed



1 December 2006

The Met Office confirms that the autumn 2006 has been the warmest in the last 347 years across central parts of the UK.

Central England Temperature records dating back to 1659 are the longest instrumental temperature records in the world, and autumn 2006 has been warmer than any equivalent autumn since then. The provisional mean temperature this year was 12.6 °C. The previous highest figure for the equivalent period was 11.8 °C, recorded in 1730 and 1731.

The provisional UK-wide mean temperature for autumn was 11.3 °C, beating the previous record set in 2001 of 10.5 °C, in a temperature series that began in 1914.
