To see what the weather will be like I find it best to just look out of the window and see for myself then make a decision based on that. Better than the useless forecasts these days. I reckon it's the crap climate/weather models they use these days, probably based around the nonsense idea that CO2 is a major force in what happens.
Are you trying to start a fifty page argument about climate change?
Anyone got any crisps?
