Is global warming cause by man made CO2 or is just a natural cycle? (world, race)

[DanielRead]

I got stuff to post that will make you think twice.

[GH0ST..]

probably both

[TXboomerang]

Its because of Republican made CO2.

I think that the problem we are experiencing right now is mostly a manmade issue right now (a very quick change in temperature) but I do believe that there are natural cycles as well. I don't think anyone disputes that.

Well, personally... I think it's a cycle that humans have sped up.

I mean, the ice age happened, why not an extreme heat period?

If you look at the charts not just from the 1700s and up, you'll see that the earth is due for another warm up. Of course, I'm sure that man is impacting this temperature change at least a little. A little environmental protection never hurt anyone, though.

[Nothing12]

of course its a man made issue, this is like asking "Is the earth flat?"

[ArizonaBear]

Not so long ago; the scientists were predicting 'Nuclear Winter', anybody remember that scenario?

[Wild Style]

what about a option that says someone recognizes that the world goes through cycles (ever heard of the ice age?) but that our collective actions as the human race can impact that cycle and alter it in negative ways?
