This Antarctic glacier is cracking from the inside out — and that’s bad news for all of us
Because of rising sea levels
A massive glacier at the edge of the West Antarctic Ice
Sheet is cracking from the inside out at accelerating speed. That’s
alarming because this glacier — and others — function like corks in a
bottle: they keep the ice from flowing into the sea, which would raise
sea levels by several feet.
The glacier, which is described in a paper published yesterday in Geophysical Research Letters,
is called Pine Island Glacier. In 2015, a 224-square-mile iceberg broke
off from the glacier. After studying satellite images before and after
the event, researchers at Ohio State University found that in 2013, a
rift formed at the base of the ice shelf, 20 miles inland. The rift
worked its way up for two years until it caused the iceberg to break
off.
Icebergs do separate from ice sheets in the Antarctic on a
fairly regular basis. This one, though, is special. It confirmed what
glaciologists have long been suspecting: that the ice shelf is
weakening. But it also shows that the ice retreat is happening farther
inland than scientists had previously observed.
“It’s generally accepted that it’s no longer a question
of whether the West Antarctic Ice Sheet will melt, it’s a question of
when,” study leader Ian Howat, associate professor of Earth sciences at Ohio State, said in a statement.
If things continue the way they are, glaciers will keep melting, and
West Antarctica will significantly collapse “in our lifetimes.”
In the case of the 2015 iceberg, researchers believe that
the rift began deep down the ice shelf, where warming waters are eating
away at the ice. That’s a new threat to the Antarctica ice sheet, where
rifts usually form at the margins, not deep inland. Similar breakups
had been observed in Greenland and the global consequences of melting
ice in these regions are huge.
The Antarctic and Greenland ice sheets contain more than 99 percent of the freshwater ice on Earth. Previous papers
have shown that the melting of the West Antarctic Ice Sheet is
inevitable, and it could raise sea levels by as much as 10 feet. In the
US, that would mean that cities like New York and Miami would go
underwater.
