Models predict that the Arctic Ocean could be ice-free in summer by the year 2035. The melting ice wouldn’t just be a victim of climate change; it would drive further warming. Compared with bright ice, which serves as a cool topcoat that insulates the ocean from solar radiation, a dark, ice-free ocean would absorb far more heat. To help slow the thaw, a group of engineers has proposed coating Arctic ice with glass microspheres, or tiny, hollow bubbles, which would increase the amount of light reflected. But the idea of addressing climate change by intentionally intervening in the natural world—as opposed to by decreasing emissions—is deeply contentious. “If we have the opportunity to preserve an irreplaceable part of the planet’s climate system, don’t we have the responsibility to do so?” Rachel Riederer writes. “And yet spreading an artificial substance in a delicate ecosystem, even in the name of environmentalism, is troubling to the part of us that wants nature to remain as it was.” At the link in our bio, read more about the new method for potentially protecting the world’s most important ice, and why some activists oppose it.
