Minchew is among the many researchers trying into potential plans to change the way forward for glaciers. Methods being proposed by teams world wide embody constructing bodily helps to prop them up and putting in huge curtains to sluggish the move of heat water that speeds melting. One other method, which would be the focus of Arête, is known as basal intervention. It principally entails drilling holes in glaciers, which might enable water flowing beneath the ice to be pumped out and refrozen, hopefully slowing them down.
When you have questions on how all this could work, you’re not alone. These are nearly inconceivably big engineering tasks, they’d be costly, they usually’d face authorized and moral questions. No person actually owns Antarctica, and it’s ruled by an enormous treaty—how may we probably determine whether or not to maneuver ahead with these tasks?
Then there’s the query of the potential uncomfortable side effects. Simply take a look at latest information from the Arctic Ice Challenge, which was researching methods to sluggish the melting of sea ice by overlaying it with substances designed to mirror daylight away. (Sea ice is totally different from glaciers, however among the key points are the identical.)
One of many undertaking’s largest discipline experiments concerned spreading tiny silica beads, kind of like sand, over 45,000 sq. ft of ice in Alaska. However after new analysis revealed that the supplies may be disrupting meals chains, the group introduced that it’s concluding its analysis and winding down operations.
Reducing our emissions of greenhouse gases to cease local weather change on the supply would definitely be extra easy than spreading beads on ice, or making an attempt to cease a 74,000-square-mile glacier in its tracks.
However we’re not doing so sizzling on reducing emissions—the truth is, ranges of carbon dioxide within the environment rose quicker than ever in 2024. And even when the world stopped polluting the environment with planet-warming gases right now, issues might have already gone too far to avoid wasting among the most weak glaciers.
The longer I cowl local weather change and face the scenario we’re in, the extra I perceive the impulse to at the least take into account each possibility on the market, even when it feels like science fiction.
