Oh, S—

BBC NEWS | Science/Nature | Antarctic glaciers surge to ocean:

Throughout the 1990s, according to satellite measurements, the glacier was accelerating by around 1% a year. Julian Scott’s sensational finding this season is that it now seems to have accelerated by 7% in a single season, sending more and more ice into the ocean
….
If the glacier does continue to surge and discharge most of it ice into the sea, say the researchers, the Pine Island Glacier alone could raise global sea level by 25cm. That might take decades or a century, but neighbouring glaciers are accelerating too and if the entire region were to lose its ice, the sea would rise by 1.5m worldwide.

What was that about irrevocable tipping points?

Even 25 centimeters means that a lot of places that are now dry during storm surges will suddenly find themselves under water. And 1.5m pretty much takes out everything coastal around the globe…
