Global Warming - Caused by Man?

MetalMosher

Hello Boards.ie users!

I am writing to you with an urgent request.

We are currently in a debate with a Dublin debate organisation on the topic of "Global Warming- Does man accelerate it?"

We are browsing the internet and reading books trying to find proof to back up our view that MAN DOES ACCELERATE IT.

I am asking for your assistance. Recommend websites and reports to me, and please give information asap.

Thank you.

David.

i dunno, show em a graph like this one:
http://whyfiles.org/211warm_arctic/images/1000yr_change.jpg

Basically any temperature chart spaning the eons i've seen show a marked upturn starting around the turn of the last century.
Mirrored exactly by the estimated C02 content of the atmosphere, which in turn is conveniently echoed by man's burning of fossil fuels.
Although there are other sources of C02 emissions.
Deforestation being one. (which is done by man)

Here's another graph, this one showing Global Fossil Carbon emissions by type:

Actually just read the wikepedia article:

his articles are good for grabbing stuff from and the refernces at the bottom of each are good for quoting. You'll need a good few arguements if the opposition bring up things about the models used for calculatiing mans effect leave out measurements ( the impact of clouds and water vapour for example )

Beware the vapor trails argument!

Vapor trials cause "global dimming" which has ironicly held back some of the worst effects of warming so far as dimming helps supress the temperature.

Get a few copies of the last few weeks Sunday Telegraph articles by a well known UK professor that says most of this is bunkum.He goes into the myth peddling of Al Gore and the UN climate changes etc.As well as that there is a reply by Al Gore on this as well.Draw your own conclusions.
I'm skeptical about the whole thing.Being green is becoming another big busisness.
