Iceland Rising 1.4 Inches a Year, Thanks to Climate Change

A research team from the University of Arizona has discovered that due to the increasing threat of climate change and melting glaciers, Iceland is rising as much as 1.4 inches a year, Fox News reported.
The team studied the Earth's crust under Iceland for years and discovered the rebounding and relatively rapid rising pattern, which all coincided with the melting of the great ice caps due to climate change.
Their paper, which is set to appear in an issue of Geophysical Research Letter, detailed the discovery and stated that "the current fast uplift of the Icelandic crust is a result of accelerated melting of the island's glaciers."
They shared that the rising began about 30 years ago around the same time that the warmer climate and subsequent melting began.
"We used 62 GPS stations located all across the island of Iceland, and looked at how fast those GPS stations were moving upward through time," shared Kathleen Compton, first author of the study and a geosciences doctoral candidate at the University of Arizona.
She told Fox News, "They're not only moving upward very rapidly in the central and southern part of the island, but they're speeding up over time and moving faster and faster each year."
To explain further, Compton used the trampoline effect, according to PRI.
"The weight of that person is going to make the trampoline sag beneath them. If they hop off, the trampoline regains its shape," she said. "The weight of the ice is so much that it makes the surface of the Earth sag."
Because of that, other areas end up rising, Iceland among them.
Sigrun Hreinsdottir, one of the investigators of the study, told Washington Post that the same "rebound phenomenon" had been observed in Scandinavia and Canada and, more recently, Chile and Alaska.
Iceland is so far the only country to prominently display the trampoline effect, springing up at a rapid rate, especially with how every year the island loses about 11 billion tons of ice from the warming climate, Washington Post reported. They hypothesized that come 2025, it's possible that Iceland could rise even faster at around 1.6 inches per year. That's about the same as the growth rate of an average elementary school student, the report explained.
This does not bode well for the rest of the world, but it also doesn't spell good news for Iceland in particular. The island sits on top of one of the world's most active volcanoes, which currently contains molten magma. If the melting glaciers affect the pressure around the volcano, it could feed Iceland's Bárðarbunga volcano, which has already been spewing lava since August last year, according to Washington Post.
