I cant really say that I can believe that global warming exists nor can I say it does.

What do you think?

I'm not sure either way about this. 30 years ago scientists were "certain" we were entering a new ice age. Nevertheless the evidence for global warming's occurence is fairly convincing, ie. icecaps melting.

I don't know anymore.
Why should we even believe the icecaps are really melting? I've heard about expedition "proving" Antarctica is melting but also expeditions "proving" it's not.
What are we to believe?

While I am not convinced that global warming occurred, I am certain that it was not us that caused it.

certainly if you look at the temperatures that the earth has been in the past we are due for a warm period at the moment but some people would say that it is been exasperated* by human activities.

Actually, we did cause it.
Yes, it is real and it's happening.
Us, humans, have ruined this beautiful world thinking were the only ones alive on this planet. We were too focused on how OUR future would look, but now look what's happening. There's so much around us going on, you can't even tell what will happen tomorrow.

1. Could you provide some evidence to back that up please? I could go on the other forums and post "GOD DOES NOT EXIST!" everywhere but no one would take me seriously so I have to try and prove it rationally.

2. Suprisingly often we can tell what will happen tomorrow. Yesterday the weather forcast here for today was for a warm but overcast day and they actually got it right.

It's happening too fast for us to not have some kind of effect. Plus, the temperature of the Earth and the amount of CO2 matches up too well. Not a coincidence.

I would question that from a statistical point of view. Between 1905 and 1940 on your graph there was no noticable rise in CO2 but the change in temperature is, if anything, more dramatic than it is for 1945 - present when the CO2 levels started rising quickly.

Good observation. It is a known fact, however, that more than just CO2 effects temperature. So perhaps what caused the first spice was something else? I have no idea.

Really what is most amazing is the speed of this change.

We have never experienced change this fast before. Ever. I find it hard to believe that we aren't having at least some affect on this.

If it hasn't been said, it's a natural cycle. Humans are speeding it up, though.

I agree with you but I felt the point needed to be made.

Of course the same factors you ellude to which all individually cause fluctuations in temperature may be simply acting together for the first time in history entirely by coincidence.

True. As Strelok said, to see this kind of a change probably means it is a combination of natural and man-made factors.

It seems a shame to find an answer so quickly. We really need some die-hard environmentalists and a couple of irrational environment-haters to slug it out for a while for our own amusement.
