This is exactly the point that never seems to be addressed by the 'sceptics'.
If all we had was a noisy graph of global temperatures, then it would mean very little, and certainly wouldn't prove we were the cause of any increase.
But we don't have just that. We know that CO2 is a greenhouse gas and can quantify its effect. And we know that we are pumping CO2 into the atmosphere and can quantify how much. And these things are extremely well understood and connect to vast quantities of other science and technology that no one seems to think is in doubt. And we put these two things together and we know we are raising the temperature.
Which bit of this reasoning is the problem?
