Andy,
I'm deffo open to discusstun on this sorta subject, and don't worry about making enemies! This is the type of discussion the forum needs, so Hi-Five for ya!
I'm with you on your thoughts. You look at the average cold temps and severity of the last two winters at least.... More snow than we have had in years, a national shortage of salt, bad frosts and ice too.
Also as you mentioned, the top temp for the UK this year being 27. That is cold. Dunno about global warming, seems more like global cooling to me. We did have a dry summer in the south, with a few nice weeks in a row. But they certainly weren't hot weeks.
I agree with you on the models too. We have been very frustrated over the summer with checking data in regards to T/Storm potential. You look at the models and yeah, for a few days ahead they look good, but as you get closer to the day in question, it's totally different. So how they can predict a weather event or average temp in 100 years is beyond me.
I di however do my bit naturally, by recycling, walking to the local shop etc instead of driving, but this just personally makes me feel better.
