Scientists have discovered vast systems of flowing water in Antarctica. And that worries them.

The Ice Sheet that covers Antarctica has large networks of rivers and lakes, but scientists have only just discovered them. Glaciologist Alison Banwell from The University of Cambridge said the following about the research “A handful of previous studies have documented surface lakes and streams on individual ice shelves over a span of a few years,”  she also said “But the authors’ work is the first to extensively map meltwater features and drainage systems on all of Antarctica’s ice shelves, over multiple decades.” Scientists say that all of this flowing water could increase the rate the ice sheet melts. Meltwater destabilizes glaciers and that is what is worrying scientists.

The melting of Antarctica is a massive contributor ti the raising sea levels, which in the future, will have huge effects on coastal communities. The raising sea level will trigger many other natural disasters.

One thought on “Scientists have discovered vast systems of flowing water in Antarctica. And that worries them.

  1. Researchers originally believed that most of Antartica did not experience extensive melting during the summer, but newer evidence is proving this probably isn’t the case. Currently, melting has only been detected on the edges of the continent; however, climate change could cause melt water to pool under the the continent’s floating ice shelves which would move inland glaciers towards the ocean and trigger a more dramatic rise in sea levels.
