Unprecedented? It's happened before way before man ever crawled out of the proverbial ooze.
Earth has had world wide floods, world wide droughts, world wide fires, extinction of life, tectonic activity so great it broke apart land masses, total loss and gain of the ozone layer, hell earth has a complete reversal of the poles. Millions and in some cases billions of years before man. So Antarctica getting warmer and even melting has happened before. We have countless research and evidence from scientists allover the world proving it.
