Sure, and I'm happy a meteor wiped out the dinosaurs so we mammals could take over… but I'd be a bit saltier about a new one hitting tomorrow.

That ice melting absorbs the energy that would otherwise be warming the atmosphere and causing cataclysmic storms and crop failures due to heat. And that is exactly what is going to happen once the glaciers melt.

The people worried about melting glaciers are not laminating the loss of pretty ice. They are worried about where this extra energy will go once there is no more ice to change phase and absorb it.

The planet's rising temperatures will be the least of some regions' concerns as the knock-on effects from the redistributed water will be much, much deeper than current awareness.

The mass of ice on the earth's poles has also led to the shape of the planet via tectonics over thousands of millennia. As that mass melts and redistributes from a solid to a liquid spreading around the globe our spheroid will begin to rebound. We have sensors everywhere, even in space, so the resulting effects will not be a surprise to some when the 'mass'ive shift begins. As those tectonic events increase in frequency so too will volcanic activity so I ask if anyone else has been checking on such data?

We do not know what we do not know however we act like we know everything yet learn new things about the planet daily. The things the survivors are going to learn about the changes that are setting in will be the last thing those that did not survive experienced from those cataclysmic moments.
