Interesting, but too many uncertainties at this time to reach any firm conclusions. The river system is ‘beneath kilometers of thick ice’.

Scientists at Imperial College London, the University of Waterloo, Canada, Universiti Malaysia Terengganu, and Newcastle University have discovered an unexpected river under the Antarctic ice sheet, says Tech Explorist.

The discovery of this 460km-long river shows the ice sheet’s base has more active water flow than previously thought, which could make it more susceptible to changes in climate.

The river is believed to affect the flow and melting of ice, contributing to the acceleration of ice loss during climate warming.

Co-author Professor Martin Siegert, from the Grantham Institute at Imperial College London, said: “When we first discovered lakes beneath the Antarctic ice a couple of decades ago, we thought they were isolated from…
