Thaw, by Timo Lieber


As Arctic temperatures continue to rise, the ice sheet loses out, primarily, through increased surface melt and runoff into the ocean.

These lakes rapidly drain through the ice sheet, lubricating its bed, causing the ice to flow faster towards the ocean where it melts and calves icebergs.
