As others have stated Bill Gray is out of his league here. He's most renown for providing his tropical storm forecast for each upcoming season, and has had varying degrees of success with it (with recent notable failures). Perhaps he fancies himself an expert on climate change because of his understanding of tropical storms and ocean currents; but this is like me considering myself an expert on hurricanes because of my understanding of thunderstorms. He is quickly losing any credibility in my eyes as he continues to assert, without any evidence whatsoever, that "it's all the ocean's fault."

I naively thought that once the latest IPCC report came out a most of the "debate" on climate change would be finally resolved. I was wrong. If anything, the increasing evidence has caused more people to come out of the woodwork. Humans are strange.

Anyone who wants to enter the fray of the physics of climate change should at the absolute, very least, get an introductory meteorology college textbook and study the chapter on radiative transfer. Learn, and begin to understand, that, in an idealized all-else-remain-the-same situation where you increase the greenhouse gas concentration for the Earth, it is absolutely certain that the radiative equilibrium temperature will go up. Once you start from that point, then you can start to talk about the uncertainties, feedbacks, etc. So many armchair climatologists seem to want to jump straight to the uncertainties before they even have the most basic grasp of the fundamental physics of radiative transfer etc. Quite frustrating.
