Iceland Rises as Its Glaciers Melt From Climate Change

The 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 upward as much as 1.4 inches per year — a speed that surprised the researchers.

"Our research makes the connection between recent accelerated uplift and the accelerated melting of the Icelandic ice caps," said first author Kathleen Compton, a UA geosciences doctoral candidate.

Iceland's glaciers (white) are melting faster and faster. As a result, the Icelandic crust near the glaciers is rebounding at an accelerated rate — in some cases, as much as 1.4 inches per year, a UA-led team of geoscientists found. The researchers used Iceland's geodesy network of sensitive GPS receivers (red triangles) to determine how fast the land is rising.
