There are things you'd like to count on, and gravity is one of them, yes, even when you're at the top of a ladder. Here's the thing. Ice has mass; it's heavy because it's water, which is pretty heavy, just ice is just a tad less dense than water, which is one of the few substances whose solid form is less dense than it's liquid phase. Now what is happening is that a lot of ice is melting in Antarctica, so much that the loss of this mass is ever so slightly altering gravity; it's a tiny bit less down there now. When you start messing with gravity, people should start paying attention. Just think how much ice has to melt to affect gravity! It's that darned old global warming to blame. Oh yes, and the water that was ice, what about that? Well, goodbye Florida, goodbye Louisiana. Will their governors go down with their states denying all the way? Sure.
