It can sometimes be hard to know who to believe. Climate change science is very complicated ranging in disciplines from oceanography through astrophysics to atmospheric chemistry to polar research. And then of course there are the skeptics ......
Help is at hand though there is an excellent web site 'RealClimate - climate science from climate scientists' which really helps. There are hundreds of archived blogs which will help you navigate through either controversy or ambiguous media reports or just complicated science.
For example there was a highly mischievous Channel 4 documentary in 2007 - the Great climate Change Swindle which challenged much of the science behind climate change models - how comes vineyards flourished in Britain in Roman times; how comes the CO2 temperature graphs from polar ice cores show temperatures rising before CO2 levels?
Well RealClimate goes into these matters in some detail which will help you argue that climate change is real and is caused by man with any one down the pub!

Is it information such as this
"CO2 doesn't match the temperature record over the 20th C. ... They presented this as a major flaw in the theory, which is deeply deceptive, because as they and their interviewees must know, the 40-70 cooling type period is readily explained, in that the GCMs are quite happy to reproduce it, as largely caused by sulphate aerosols"
that you are thinking of?
This certainly does provide "accurate scientific information" in that it demonstrates that the writer is only somewhat distantly familiar with actual science.
Specifically, to say that the drop of temperature is sorted because the models predicted it is a) absurd - I have a phd in data analysis and have seen more fiddled models from academics that you can shake a stick at, and b) is quite clearly "assuming the answer", in that if we are going to assume the "models" are correct, no debate is required. The whole point is that I and many others think they're nonsense.
Maybe a reason for the drop consistent with AGW exists, maybe not. But the folks at RealClimate certainly don't have one. Do you know anyone who does?
