After returning with frozen fingers from a twilight run on snow covered moorland I turned on the computer. Jim Hansen at the NASA Goddard Institute for Space Studies provides data each month on global temperatures. These are his latest conclusions:

"This has been the the warmest January-November in the GISS analysis, which covers 131 years. However, it is only a few hundredths of a degree warmer than 2005, so it is possible that the final GISS results for the full year will find 2010 and 2005 to have the same temperature within the margin of error.

"The cold anomaly in Northern Europe in November has continued and strengthened in the first half of December. Combined with the unusual cold winter of 2009-2010 in Northern Hemisphere mid-latitudes, this regional cold spell has caused widespread commentary that global warming has ended. That is hardly the case. On the contrary, globally November 2010 is the warmest November in the GISS record."

Well, all that I can note is that our weather is getting more extreme. Both cold and hot.

When does weather change technically become climate change?

Because if you 'average' data across the world what statistical/mathematical reliance can you put on that? "A few hundreth's of a degree".

Put another way, when trying to produce audited accounts you are out by 5 pence. In principle this looks like a good result. But it could also mean that you were GBP +5 million and 5 pence, and GBP - 5 million. Difference 5p.

But 5 million unexplained for.
