” It should not be hard to imagine that the Earth is in some sort of dynamic equilibrium in terms of how much ice it has.”

Not hard to imagine.
Just incredibly wrong.
You do not know what the normal amount of ice on the Earth is.
For millions of years the Earth has fluxed between Ice Ages and warm periods.
It is not warmer now than any of the previous warm periods, predictions of inexorable warming are busted, and the entire concept plays on the fact that any further Ice Ages , though possible, are unimaginable.
Imagine that.
