Cutting out the trolling:
"Climate scientist James Hansen said that Dyson "doesn't know what he's talking about… If he's going to wander into something with major consequences for humanity and other life on the planet, then he should first do his homework – which he obviously has not done on global warming."[78] Dyson replied that "[m]y objections to the global warming propaganda are not so much over the technical facts, about which I do not know much . . . "

What is so hard to understand about this, PoS? If a person says they do not know much about how AGW technically works, then that person is not an authority on whether climate scientists have got the technical facts wrong.
