Interesting discussion. I'm divided on this one.
One one hand I believe we have barely even begun to understand how interactions, between the many variables that influence our climate, actually work. Hell we don't even know what all the variables are! Our climate models are just coming out of the stone age, I mean, they are just now starting to include the oceans in their models! We still don't even understand exactly how the oceans affect climate.
We are slowly learning! Our ability to capture, and understand the data, captured over the years from our instruments is constantly improving. Our ability to extract climate data from ice cores, tree rings, and rock samples is truly amazing. However, we have a long way to go before we will truly understand how all the variables involved in climate really work.
But... Just because we don't really understand how all this works, and the fact that some of the data may be flawed by our capture techniques, or by our not understanding it, or even by outright falsification, does not mean we should ignore the fact that CO2 levels ARE increasing, and we ARE one of the causes. If we wait until we truly understand what is happening, I'm afraid it will be too late for planet earth. (Think Venus)
I know that in reality, it will be impossible to get the world as a whole to stop, or even slow down carbon emissions. The world currently has nothing to replace it's carbon burning for energy with! China, India and the some smaller countries do not have the will, nor the ability, in some cases to implement such plans. Here in the US politics as usual will prevent it from EVER happening.
Oh, one last thing. Anyone who thinks Donald Trump is going to help with this issue is smoking something...
Anyway just food for thought...
