Thwaites Glacier: The ‘Doomsday Glacier’
Geoengineers are embarking on an ambitious plan to test massive underwater curtains in a bid to combat catastrophic glacial melting. The focus is on the Thwaites Glacier, ominously dubbed the “doomsday glacier,” which has lost over a trillion tons of ice since 2000. The potential collapse of Thwaites could lead to a staggering 10-foot rise in global sea levels, impacting millions worldwide.
Stakes Are High for Coastal Communities
The repercussions of a 2-foot rise in sea levels would be dire for cities like New York, Miami, and New Orleans, facing devastating floods. A collapse of the Thwaites Glacier could set off a chain reaction, causing other glaciers to melt and amplifying the rise in sea levels by another 10 feet. The urgency to address glacial melting is evident, with time running short to avert a crisis.
The Innovation: Underwater Curtains
Leading the charge is glaciologist John Moore, who proposes installing colossal 62-mile-long underwater curtains to shield glaciers from warm seawater. The curtains aim to interrupt the flow of warm currents that erode the glaciers’ edges, buying crucial time for the ice shelves to stabilize. This novel approach shows promise in slowing down the melting process and potentially saving vulnerable glaciers.
A Race Against Time and Funding
As the research progresses, the need for substantial funding becomes apparent. Moore estimates a staggering $50 billion is required to implement these innovative curtains effectively. The urgency to act swiftly is underscored by data showing rapid glacial melt rates. While some experts advocate for drastic reductions in carbon emissions, Moore stresses the importance of exploring diverse solutions to combat glacial melting before it’s too late.
