Minchew is among the many researchers trying into potential plans to change the way forward for glaciers. Methods being proposed by teams around the globe embrace constructing bodily helps to prop them up and putting in large curtains to gradual the circulation of heat water that speeds melting. One other method, which would be the focus of Arête, is named basal intervention. It mainly includes drilling holes in glaciers, which might enable water flowing beneath the ice to be pumped out and refrozen, hopefully slowing them down.
You probably have questions on how all this is able to work, you’re not alone. These are nearly inconceivably big engineering initiatives, they’d be costly, they usually’d face authorized and moral questions. No one actually owns Antarctica, and it’s ruled by an enormous treaty—how may we probably resolve whether or not to maneuver ahead with these initiatives?
Then there’s the query of the potential negative effects. Simply have a look at current information from the Arctic Ice Undertaking, which was researching easy methods to gradual the melting of sea ice by masking it with substances designed to mirror daylight away. (Sea ice is completely different from glaciers, however a few of the key points are the identical.)
One of many mission’s largest area experiments concerned spreading tiny silica beads, type of like sand, over 45,000 sq. ft of ice in Alaska. However after new analysis revealed that the supplies is likely to 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 will surely be extra simple 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 slicing emissions—in actual fact, ranges of carbon dioxide within the ambiance rose quicker than ever in 2024. And even when the world stopped polluting the ambiance with planet-warming gases in the present day, issues might have already gone too far to avoid wasting a few of the most susceptible glaciers.
The longer I cowl local weather change and face the scenario we’re in, the extra I perceive the impulse to not less than take into account each choice on the market, even when it appears like science fiction.
