If you do watch it, be aware that apparently he presents a completely out-of-leftfield figure for how much the sea level is calculated to rise by 2100 (20 feet when the consensus worst-case estimate is 35 inches).
Otherwise the skeptical environment scientist (in the "global warming is happening, but he's skeptical as to how much it is a result of human activity" camp) I know felt the numbers presented were reasonably accurate even if he differed in the final conclusions.
