You will find ZERO scientific organizations that state "humans caused global warming". What they do PROPOSE is humans have created an environment that "tipped the scale" of CO2 conditions in the atmosphere that "contributes" to global warming. Read friend. Read.
Here is a scientifically accurate statement of what scientists actually believe:
In a nutshell, humans are causing the global warming which is being observed now.
The "tipped the scale" is referring to equilibrium---natural greenhouse effect of course raises temperature above what an atmosphere-less Earth would be, but that is not the issue.
Note that human cause of global warming does not invalidate natural causes of global warming in geologically ancient times, however similar natural causes today would also result in clear experimental observations and mechanisms which are not observe today.edit on 4-9-2012 by mbkennel because: (no reason given)edit on 4-9-2012 by mbkennel because: (no reason given)

Good grief! Do I have to teach logic 101 again?!
Even tho your statement is www.merriam-webster.com... (many fox “news”enthusiasts do not know what contentious means) , lets suppose that what you imply is correct , that comparing human influence on the environment to natural effects will show that the sun and earth have a greater influence on earth then man. DUH!
SO WHAT! If you have a leak in your gas tank , speeding up ( a human willed event) will still be a stupid thing to do!
I’m sure you will argue that ultimately, the sun is to blame and not humans. DUH!! That is like saying that if the thermostat is on high, that is the ultimate reason for the room being hot (greenhouse) and opening a window will do no good. DUH! Obviously, only a fool would not open a window if the thermostat was stuck.

Then of course the Oregon petition will be brought up
According to the Oregon petition if you have a B.S. degree you are a climate scientist!!! DUH!
Then of course “climategate”
The made up charges by the illegal hackers were found to be silly. For example, when a scientist said that he found “a neat trick” , it was as suspicious as a mathematician that said,” I found a neat trick to solve this calculus problem quicker.”
YAWN! The tin foil hatters are easy to debate and win against. Humans have contributed to global warming and the entire scientific community agrees!

Do any of you remember global cooling and a new ice age??? How can science be so wrong as to first predict global cooling then all of a sudden global warming?? If they were wrong then what makes you think they are not wrong now??? I am not disputing that CO2 levels have changed or not but how are they sure that this will cause what they predict. Science has been wrong before.. or do we just forget that possibility?? People have so much stock in evolution yet they do not believe the world can adapt to this situation. Our earth has seen many different things.. I mean our geographical layout was very different in the past yet we were not around to cause "global warming" to cause those changes at that time. What makes people think we will not adapt to any changes caused to our planet man made or not. Is evolution real or not?? This is a chance to put your money where your mouth is
Global cooling was a conjecture during the 1970s of imminent cooling of the Earth's surface and atmosphere along with a posited commencement of glaciation. This hypothesis had little support in the scientific community, but gained temporary popular attention due to a combination of a slight downward trend of temperatures from the 1940s to the early 1970s and press reports that did not accurately reflect the scientific understanding of ice age cycles. In contrast to the global cooling conjecture, the current scientific opinion on climate change is that the Earth has not durably cooled, but undergone global warming throughout the twentieth century.
