Here is the evidence taken directly from Met Office records, and yet the Met Office scientists seem strangely reluctant to follow this up. It may be due to the Clean Air Act, as suggested, though it might be due to a reduction of cloud cover. Our atmosphere changes throughout the day and it is virtually impossible to know every change and so computer programmes can never be accurate.

ReplyDeleteCorrect, but the models can still give a useful guide about global averages with error bounds.
Eg, if we look at a traditional washing machine in action (lid up), we can't predict the exact height of the water/foam at any spot at any time, BUT we can say with a fair amount of confidence that if the drain is open that in a minute or so the water level on average will be very low (or conversely will be higher if we are adding water).
We know how CO2-greenhouse works and most of the related physics so we can say useful things about average values over time even without being able to predict the temperature (weather) in precise locations at any moment.
My reply is that as the temperature changes are so small, even a slight error is enough to make the climate models so far out that they are pretty well useless. In fact it is the models that are used as evidence to put in place the ruinous policies that we are now suffering with.
