I'm sure I can dig some things up.
I dont' have a lot of time right now, so I'm just going to throw some links at you in the hopes you'll find them interesting. I'm assuming you want evidence of climate change being not attributable to nature, rather than evidence of the UK's weather records.
I will try to find something more detailed tomorrow.
Greenhouse gas emissions
climate change more serious than previously thought
sun dimming
troposphere warming
The consensus seems to be that scientists are worried. Granted, these links are all from the BBC and I'm well aware of the inherent untrustworthiness of relying on one source. As I said, I'll expand when I have more time.
From everything I've read on the subject, and I have read a fair bit being interested in it, the most positive thing we can now look forward to is maybe avoiding the most catastrophic effects. It seems we're already too late to actually reverse anything.

I was not interested in the rather repetitive talks about climate change, but your claims about:
"Britain has been taking records of the weather patterns since 1659. Studies of it have shown that the increase in the temperature has less than a one percent chance of occuring naturally. The temperature in central Britain has risen by a degree in the last forty years alone.
350 years of continuous records are hard to argue convincingly against."
Only the last link really made any comments about long term temperature change, but it was only talking about data that was readily available because of satellite information.
As an aside, the global dimming one is rather interesting. If we were receiving less solar radiation, that would have a negative impact on "global warming." Unless we assume that the air pollution is a significantly large block for the natural radiation of the Earth, that it makes up for the decrease in solar radiation.
