The range between the min and max temps for the last 100 years is under 1°C globally. For the last 1,000 years it's just over 1°C (from wolfram alpha at least). It's clear that temps are slowly rising, but the constant reports of extreme weather seem at odds with the data to me. Is 1°C over 1,000 years really doing all this? When I read articles about the weather I have to remind myself what the data says. If I didn't check occasionally I'd think we'd increased by 10°C in the last 5 years.

For the record, I drive an electric car and my house is supplied by a purely renewable provider here in the UK. I hate the thought of polluting the planet and I do what I can to live a green life. I really love science and study as much as I can, but reading about global warming is very different to reading about quantum electrodynamics or special relativity. I'll happily watch the oil companies go under and I think dumping tons of crap in to the atmosphere is clearly terrible and shouldn't go unpunished, I just wish I had some better data to back this all up.

Has anyone got good sea level rise data for the last 1,000 years? Again, when I read any article I feel like the sea must have risen by a few meters already as everything is so dramatic, but I can't find a decent dataset that sets out what has actually happened.
