I don't generally crow about "I'told you sos", but it seems the UK has just had the coldest December in 30 years. Now it is January and the Met Office are now predicting yet more snow and sub-zero temperatures. More Severe Weather warnings have been issued.
This is a world away from from the mild winter predicted earlier.
One suspects the sharp contrast between the long term forecasts and the actual weather we get may be driven by more a tendancy to slant long term forecasts towards the warmest possible outcome, based on a conviction of the reality of global warming and maybe a problem with connecting possible climate change with actual climate.
