The big issue for many is that no one can say how much of the increase in temps is caused by humans. 1% or 99%?
How can we say something is increasing the temps if we do not know what the temp would be without the increase?
Not even a rough range is ever stated in any study.
The only amount I have ever actually read was something like "any possible increase by himanity is within the margin of error of the calculations".
