A global warming data point is revised
Yes, that Antarctic glacier is melting faster nowadays. But the Pine Island Glacier melt may not be due to global warming. A submersible research device found that it had been sitting on top of a previously unknown rocky ridge, which had heretofore blocked its progress. Now the glacier has separated from the ridge, and so the glacier is flowing unimpeded, and hence faster, into the sea, and therefore melting faster.
It'll be interesting to see if this finding holds up, and how it is worked into the greater skein of climatology. I wish I understood the math, so I could follow this discipline more attentively.
