The Download: saving the “doomsday glacier,” and Europe’s hopes for its rockets

The Thwaites glacier is a fortress larger than Florida, a wall of ice that reaches nearly 4,000 feet above the bedrock of West Antarctica, guarding the low-lying ice sheet behind it. But a strong, warm ocean current is weakening its foundations and accelerating its slide into the sea. Scientists fear the waters could topple the walls in the coming decades, kick-starting a runaway process that would crack up the West Antarctic Ice Sheet, marking the start of a global climate disaster. As a result, they are eager to understand just how likely such a collapse is, when it could happen, and if we have the power to stop it. Scientists at MIT and Dartmouth College founded Arête Glacier Initiative last year in the hope of providing clearer answers to these questions. The nonprofit research organization will officially unveil itself, launch its website, and post requests for research proposals today, timed to coincide with the UN’s inaugural World Day for Glaciers, MIT Technology Review can ...
