This Is What a Holy Shit Moment for Global Warming Looks Like
If you truly understand global warming, then you know it's all about the ice. That's what matters. Planet Earth has not always had great ice sheets at the poles, of the sort that currently exist atop Greenland and Antarctica. In other periods, much of that water has instead been in liquid form, in the oceans—and the oceans have been much higher.
How much?
According to the National Academy of Sciences, the globe's great ice sheets contain enough frozen water to raise sea levels worldwide by more than 60 meters. That's about
200 feet. And it makes all the sea level rise that we've seen so far due to global warming appear piddly and insignificant.
