Fastest-Thinning Greenland Glacier Threw NASA Scientists for a Loop. It’s Actually Growing.

Greenland’s fastest-flowing and fastest-thinning glacier recently threw a real brain bender at scientists, who realized that instead of shrinking, the glacier is actually growing thicker, they reported in a new study.

The glacier — known as Jakobshavn, which sits on Greenland’s west coast — is still contributing to sea level rise, but it’s losing less ice than expected. Instead of thinning and retreating inland, its ice is thickening and advancing toward the ocean, the researchers found.

The big question: Why is this happening?

After much sleuthing, a team of scientists from the United States and the Netherlands found that the glacier is likely growing due to colder ocean currents. In 2016, a current that passes by Jakobshavn Glacier was cooler than usual, making waters near the glacier the coldest they’d been since the mid-1980s.

  • @OP – the glacier is likely growing due to colder ocean currents. In 2016, a current that passes by Jakobshavn Glacier was cooler than usual, making waters near the glacier the coldest they’d been since the mid-1980s.

    Changes in ocean currents and heavier precipitation are known to locally increase the ice on the occasional glacier, while the rest of the world’s glaciers continue to shrink.

    I also see there is a guardian article suggesting those responsible for damaging the climate should be held accountable!

    There are no effective safeguards preventing a few powerful people, companies or states from wreaking havoc for the sake of profit or power. Though their actions may lead to the death of millions, they know they can’t be touched. Their impunity, as they engage in potential mass murder, reveals a gaping hole in international law.
