Antarctica ice melt has accelerated by 280% in the last 4 decades

The researchers, led by Richard Levy of New Zeland’s GNS Science and Victoria University of Wellington and Stephen Meyers of the University of Wisconsin-Madison, were able to recreate a broad history of the Antarctic ice sheet going back 34 million years to when the ice sheet first formed — documenting multiple cycles of ice growth and decay resulting from natural variations in the planet’s tilt.
