Can We Slow the Doomsday Glacier? Arête on Glacial Intervention and Sea-Level Risk

Inevitable

Brent Minchew is Co-Founder, Executive Director, and Chief Scientist at Arête Glacier Initiative, a new nonprofit launched to close the gap between frontier glaciology research and actionable sea-level forecasts—and to probe whether “brake-tapping” inside Antarctic glaciers can slow their slide into the sea.

Brent explains why current models still span 1–6 feet of rise by 2100—even if Paris targets are met—and how melting glaciers, especially Antarctica’s so-called “Doomsday Glacier,” drive that uncertainty. He details why glaciology remains drastically underfunded, how sea-level changes already threaten coastal economies via insurance markets, and where Arête’s first $5 million in philanthropic capital is going. He also walks through early-stage solutions—from thermo-siphons that passively refreeze ice to pumping sub-glacial water—that could “hit the brakes” on glacier flow and buy humanity time for deep decarbonization.
