  1. Ok, it's whether Bill Nye doesn't know, or purposefully lies about climate change. 0) "Authorities", "scientists" and etc. are not a reason to change opinion. Only reasonable evidence are such reason. If we have theory that contradicts undoubtful evidence, this is very likely a wrong theory. 1) Climate is changing all the time, and quite drastically. There were medieval warm period, during which grapes were common in Scotland(up till XII century) and oranges were common at the north of China. It was WARMER than now just one thousand years ago. Then there were Little Ice Age which was very cold, so even rivers is France froze. 2) Water density does decrease with temperature, but I doubt that this effect can cause reasonable raise of ocean level. Ocean level can increase if glaciers melt, but only not floating ones. 3)If there were no carbon dioxide emissions climate wouldn't be like in 1750. Climate got warmer during second half of XIX century and the beginning of XX century. It also changed much more then, than it had changed in last few decades. 4) To prove that we need to stop using fossils scientists have to present evidence that: a)climate gets warmer; b)climate change accelerates; c)it's human fault that this happens; d) model should not contradict evidence of Little Ice Age and Medieval Warm Period(like hockey stick does).
