Stephan:   I have been studying climate change for decades now. There are only two constants: 1) The timeline keeps collapsing; 2) As this happens the outcomes become ever worse than predicted. Here is the lastest, which predicts two billion climate refugees by 2100. Which is to say a complete social crisis and breakdown.

Some of the world’s most profound melting of glaciers is happening in the Antarctic; and is invisible from above.

According to a study recently published in the journal Nature Geoscience, the underwater melting of Antarctic glaciers is now occurring at a rate that is doubling every 20 years. This means that melting in the ice continent of Antarctica could soon outpace that occurring across Greenland, which would make Antarctica the single largest source of sea level rise.

The new study was the first complete underwater mapping of Antarctica, by far the world’s largest body of ice.

The study shows that warming ocean waters have caused the base of the ice near the ocean floor around the south pole to shrink by 1,463 kilometers from 2010 to 2016. This development will likely force worst-case projections of sea level rise to be revised upwards.

The water is melting the glacier ice away from the seafloor, which was acting as a sort of plug.

The current worst-case scenario outlined by the Intergovernmental Panel on Climate Change (IPCC) is just over 1.5 meters (4.9 feet) of sea level […]
