Thwaites “Doomsday” Glacier and Related Information

Antarctica’s Thwaites “doomsday” glacier is a major concern to scientists because of its high risk of collapse and its looming threat to Earth’s sea level. Recently, it’s been expressed that the glacier has the potential to quickly retreat in the upcoming years which would cause a distressing amount of damage from rising sea levels with its anticipated dissolution. Due to the warming of the planet, the Thwaites Glacier is deteriorating along its underwater base.  For more information about the glacier, see below:

b) PBS: Scientists measure how quickly crucial Antarctic glacier is melting, Jul. 25, 2022

“Scientists measure how quickly crucial Antarctica glacier is melting, Jul 25, 2022  Climate change’s connections with the extreme heat and weather events in the U.S. and around the globe have been well established. But climate change is also having a measurable impact on a much slower-moving development: the loss of glaciers and the melting of the ice. Miles O’Brien brings us this update on a scientist’s quest to chronicle what’s happening with one of the most important glaciers.”

Note: This PBS documentary indicates that the water beneath this glacier is 4 deg. C (39 deg. F).  This temperature is much warmer than ice and as a result, is making the glacier melt rapidly.  Some experts are predicting that this glacier could collapse in 3 years

“New data suggests a massive collapse of the ice shelf in as little as five years. “We are dealing with an event that no human has ever witnessed,” says one scientist. “We have no analog for this””

It’s the world’s most vulnerable glacier and key to the stability of the West Antarctic Ice Sheet, yet we’re only now getting to know Thwaites Glacier. What took us so long?

3) Erin Sikorsky, Director, International Military Council on Climate and Security (IMCCS) and Deputy Director, Center for Climate and Security recommended the following:

“The intelligence community in particular should examine the less certain but high impact long term scenarios such as the potential collapse of the Thwaites Glacier in Antarctica. The National Security Council should also consider convening a government wide climate security exercise focused on the homeland.”

“Turning to the other example of an unanticipated event, another recent study found that the ice shelf holding back the Thwaites Glacier is likely to collapse within the next five years. This will speed the melting of a structure that contains enough ice to raise global sea levels by more than two feet. The Guardian reports that the Conger Ice Shelf, with an area of approximately 1,200 square kilometers, collapsed on March 15th in a region where such events are historically uncommon. Failing to consider potential events like these when planning mitigation against rising sea levels could result in constructing inadequate protective measures, meaning that these projects would have to be expanded or possibly reconstructed further inland.”

If the doomsday glacier collapses, it will add to these numbers, While it took 60 years for the sea level to rise about 6 inches nationally, scientists now forecast that in just the next 20 years, the sea will have risen by another 6 inches.”
