Scientists stunned by Antarctic rainfall and a melt area bigger than Texas

Scientists have documented a recent, massive melt event on the surface of highly vulnerable West Antarctica that, they fear, could be a harbinger of future events as the planet continues to warm.

An iceberg lies in the Ross Sea with Mount Erebus
in the background near McMurdo Station in Antarctica,
 November 11, 2016. A sheet of meltwater lasted for as long
as 15 days in some places on the surface of the Ross Ice
Shelf, the largest floating ice platform on Earth, during the
 Antarctic summer of 2016.
In the Antarctic summer of 2016, the surface of the Ross Ice Shelf, the largest floating ice platform on Earth, developed a sheet of meltwater that lasted for as long as 15 days in some places. The total area affected by melt was 300,000 square miles, or larger than the state of Texas, the scientists report.

That’s bad news because surface melting could work hand in hand with an already documented trend of ocean-driven melting to compromise West Antarctica, which contains over 10 feet of potential sea level rise.
