Scientists have one solid theory of what happened to it.
Researchers have discovered the sudden disappearance of a large glacial lake in East Antarctica.
Scientists say the lake disappeared from the Amery ice shelf during the winter of 2019 in Antarctica. according Phys.org. It is estimated that 600-750 million cubic meters of water is lost in the ocean.
The researchers published a study their findings in Geophysical Research Letters On Friday, the authors were able to use satellite imagery of the ice capped lake to narrow the event̵7;s timeline to a week or less in June. You can see the before and after pictures of the lake for yourself below.
What happened to the lake? Scientists believe that ocean water may have already drained into the ocean due to its own weight.
“We believe that the weight of water accumulated in this deep lake has opened a fissure in the ice shelf below the lake. which is a process known as hydrofracturing causing the water to drain into the lower oceans,” said Roland Warner, lead author of the study and Geologist with the Australian Antarctic Program Partnership at the University of Tasmania to Phys.org
impact of climate change
There’s a good chance we’ll see the disappearance of Antarctic lakes. (and the Arctic) in the future as a result of climate change.
when the global temperature rises More ice and glaciers will melt. causing more lakes to melt in the process. This may lead to the emergence of hydrofracturing more and more risk. Instability for ice shelves.
Mysterious and intriguing, while the disappearance of all Antarctic lakes remains a reminder of the devastating impact climate change could have on our planet.
