>>12321287>the atmosphere at the time of the dinosaurs was comprised of co2 levels that were 300 time higher than today's while having similar sea levels.I like AJ but he really doesn't help himself when he says dumb shit which is easily discredited by a quick internet search.
CO2 levels peaked at a bit below 2000ppm (we're currently at about 410ppm) in the Jurassic. There were no ice caps and all the water on Earth was liquid; although whether this was exacerbated due to lack of landmasses at the poles is up for debate.
If Alex wanted to make some valid points then he'd do better by drawing attention to the fact that historically (meaning over the entire lifespan of the planet since it gained surface water) sea levels have on average been higher than they are today. Our present sea levels are actually quite low compared to what is 'normal' for the planet, and rising sea levels could be seen as just a natural return to the state of things after a prolonged sequence of ice ages. Human industrial output may potentially be accelerating this natural process and thus ruining our ability to respond to it in an appropriate amount of time, but either way it was going to happen.
