re: #557 Charles
Oh brother.
As I understand matters, the attribution of warming to human activity is an opinion of IPCC members, based on the absence of any other explanation and computer models which (on a circular basis) have the CO2 warming built in.
Help me out here. I have a science degree (computing and physics) and I’m now a lawyer but I am failing to see the evidence for AGW. On the contrary, the indications are that this is a scam.
