What If All The Ice Melted On Earth? ft. Bill Nye

drradonjokingly says...

Not at all sure what the excitement is about regarding a 10 m sea level rise. By the time that happens most ecosystems and climate regimes in agricultural areas will be so disrupted that at least 20% of the population will be dead from starvation or starvation induced warfare.

There really is only one environmental issue: there are too many humans occupying the planet. It may be that the only solution, in the absence of pro-active birth control will be retroactive birth control imposed by a failed agricultural system.

Doesn't the sarcasm tag mean you're being funny? You sound accurate.

But all the ice won't melt.

By the time all the ice gets melty, the freshwater will dilute the salinity of the oceans. Once diluted, the oceans will be be slightly less good at conveying heat from the equator to polar regions, which means the poles will get colder and start to accumulate ice.

Now this process may take a long time. Could be decades. Could be centuries. Could be longer. But it will happen.

But if only 3% of Earth's water is fresh water, and 70% of that is currently frozen, that's a long, slow wait for a slightly less salty ocean. I don't think your dilution theory "hold water."

I agree though, it could take decades, centuries or longer.
