Ok i am no expert on this topic, i have read none of the links posted above regarding evidence etc. I will say a couple of things though.
There is a difference between proving that the earth is suddenly getting hotter, and proving that that is due to the last couple of hundred years of industrial revoloution. We have only recently been in a position to measure any of this, how do we know this doesnt happen randomly, or regularly at some stage in the life of the earth? I see lots of graphs and stuff with lots of numbers, but i don't know where those numbers came from or how accurate they are. Im pretty sure Jesus Christ didnt have an accurate thermometer, and hadnt measured the hole in the ozone layer 2003 years ago... someone explain to me how we have data from then?
If you look at the graph I posted, you can see that the serious acceleration in warming occured at a time when we would have had very accurate thermometers. This also co-incides with an explosion in the use of internal combustion and jet engines, aerosols, CFC's etc. Man was in space in 1959; I think we were able to measure the temperature of our back gardens by then.

Secondly, what use is data taken over 2000 years in helping us to see whats going on? Sureley we would need data taken over tens of thousands of years, in order to make an accurate measurment of what is going on around us at this time, and whether it is any different to what has been going on before we were here?
I dunno, call me a dull nubins or whatever but i dont know how we can come to any conclusions or come out with blanket statements like "we are killing the earth" etc.

If it only takes us another 200 years to kill the planet, what use is it waiting tens of thousands, just so that we can get an accurate picture?
