Stephan:   Here is the latest on rise of the Iceland crust as the result of ice-melt. Like the plates in our skulls the plates of the earth are interlinked and interdependent. The uplift of the Iceland plate will result in accommodations by the other tectonic plates, and possibly more earthquakes and volcanism. This is a kind of second stage result of climate change.   Journal Reference:

Earth’s crust under Iceland is rebounding as global warming melts the island’s great ice caps, a University of Arizona-led team reports in an upcoming issue of Geophysical Research Letters.

The paper is the first to show the current fast uplift of the Icelandic crust is a result of accelerated melting of the island’s glaciers and coincides with the onset of warming that began about 30 years ago, the scientists said.

Some sites in south-central Iceland are moving […]
