There is a lot of fancy science on planet angle/solar activity and our solar orbit that explains why it was so hot and cold in the 70's. Were at the other extreme now which is why the weather is so bloody average, or in your case wet....
Global warming down to modern industrialisation, so what about the thames freezing so hard in the 1600's you could walk across, or, oh yea the fkin ice age. The planet has been getting warmer for the last 20000 years. We aint helping but hey, that's what we do (cos somebody will always be aiming to make a buck of the backs of others paranoia).
