Did you know part of Antarctica’s massive ice sheet totally collapsed 9,000 years ago—under climate conditions a lot like today’s? Scientists just found evidence that warm ocean currents triggered a chain reaction, melting ice way faster than anyone expected. If that happened again, sea levels could rise way quicker than we think. Basically, what happened in the past could totally redraw our coastlines if we’re not careful! Wild, right? #Science #Antarctica #ClimateChange
