Minchew is among the many researchers wanting into potential plans to change the way forward for glaciers. Methods being proposed by teams all over the world embrace constructing bodily helps to prop them up and putting in large curtains to sluggish the circulation of heat water that speeds melting. One other method, which would be the focus of Arête, known as basal intervention. It principally entails drilling holes in glaciers, which might permit 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 virtually inconceivably big engineering initiatives, they’d be costly, and so they’d face authorized and moral questions. No one actually owns Antarctica, and it’s ruled by an enormous treaty—how might we presumably resolve whether or not to maneuver ahead with these initiatives?
Then there’s the query of the potential unwanted side effects. Simply take a look at current information from the Arctic Ice Challenge, which was researching find out how to sluggish the melting of sea ice by overlaying it with substances designed to replicate daylight away. (Sea ice is totally different from glaciers, however a few of the key points are the identical.)
One of many challenge’s largest area experiments concerned spreading tiny silica beads, kind of like sand, over 45,000 sq. toes of ice in Alaska. However after new analysis revealed that the supplies is perhaps 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 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 scorching on reducing emissions—the truth is, ranges of carbon dioxide within the environment rose sooner than ever in 2024. And even when the world stopped polluting the environment with planet-warming gases at present, issues could 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 at the very least think about each possibility on the market, even when it feels like science fiction.
