The first continent-wide survey of its type has spotted a worrying trend on the glaciers of Antarctica: meltwater streams that are far more widespread than previously thought, suggesting the frozen continent is even more vulnerable to future temperature rises than predicted. While a lot of the drainage channels that have been spotted aren't new, the new footage recording during the survey has scientists concerned about how far they stretch, and how soon they might send Antarctica's ice shelves crashing into the ocean. The research, by a team from The Earth Institute at Columbia University, carries on the work of measuring the Antarctica melt streams that began in the early 20th century. Now though, we have the technology to build up a much more comprehensive picture of where these streams are flowing. Unfortunately, the picture isn't a particularly pretty one.
