Only my kitchen doesn't have energy saving bulbs since it's got spotlight fittings. Every other room in the house does though. I mainly fitted the energy saving bulbs to save money rather than to stop global warming. Apart from lighting, my only other electric usage is the TV, computer and washing machine so using energy saving bulbs has knocked quite a bit off my electricity bill. I did have this thought though... If everyone starts being very energy efficient will the electricity generating companies will have to put up their prices to avoid loosing money because they are selling much less electricity?

When 'proper' scientists use temperature data measured to one decimal place in a series of calculations (say for example in NWP), do they use one decimal place in every step of the calculation or do they use more but give the final result to one decimal place? In my mind, if you only used 1 decimal place in each step, then every step in the calculation would introduce a larger margin of error in your final result do to cumulative rounding errors. Can anyone stop my brain from huring and confirm how this is actually done?

Consider my CET guess rounded down to 4.7 anyway

Can you explain why the Hadley centre give the monthly CET readings to 1 decimal place and the yearly average to 2? Example: 2006 4.3 3.7 4.9 8.6 12.3 15.9 19.7 16.1 16.8 13.0 8.1 6.5 10.82

I'm going for 4.73C - This is the average February CET for Februarys where the preceeding January CET > 6.9C

Here is my pseudo-science CET guess: Wikipedia reckons the global temperature went up by 0.6C in 20th Century. YEAR CET average for past 10 years=10.46C From glancing at the UK Yearly CET data I reckon we have gone up by about 1C which is 0.4C higher than the global average. This suggests that some of the warming we have seen is due to the prevailing synoptics rather than the base temperature of the earth. I believe this means we could still get a period of 10 years with average cet of 10.06(ish) Therefore my guess is 9.9C
