While it is hard to make high confidence short-term statistical arguments using data on something as chaotic as the weather, it is easy to make statistical arguments about economic data that is tracked intensely and tabulated every which way. So, I am not impressed with the idea that the "green" solutions are worse than the disease they are intended to address.
The information I put the most trust in comes from geology and paleontology. I think that it is pretty clear that the Earth's climate is very much dependent on the atmospheric CO2 concentration. So, I tend to believe the general gist of the predictions, but don't have much faith in the numerical details for temperatures as a function of time, or the detailed effects on specific changes to climate in specific locations. And, I see that, without human effects, our planet managed to increase its sea level by 25 feet more during the last interglacial warm period (~120,000 years ago) compared to where it is, today.
So, I don't think we have a prayer of a chance to stop sea level rise from inundating coastal cities at some point in our future. but I don't see us turning our planet into an atmospheric hell like what is on Venus, either.
What we can expect is that our continuing population increase plus some pretty obvious climate changes are going to seriously disrupt our technology-dependent societies, and I expect the world situation will get quite nasty. Mass migrations are already occurring just due to the population pressures, and they are creating wars, which are creating famines in small areas, already. I do believe that climate-forced mass migrations have a serious potential to create a dystopian society as bad as we have seen in Hollywood fiction, without any happy endings.
By the time the situation has become too obvious for anybody to still ignore, we will have lost all ability to do anything to stop it. So, I am a firm supporter of doing the sensible things that can mitigate as much as possible in the time we have left. But, much of what is being pushed seems to be poorly though-out and is too often being hijacked for supporting pre-existing agendas. I fear we are going to pay a heavy price for our collective lack of objective assessment capabilities.
