00:00The sheet of ice that covers Greenland contains enough frozen water to raise oceans by 25
00:06feet across the globe.
00:08As the planet warms, glaciers melt, causing sea levels to rise.
00:12But not all of that melt happens at the surface.
00:16In the summertime, rivers and pools of meltwater find their way down through the glacier to
00:22the bed below.
00:23From there, the water runs beneath the glacier until it reaches the ocean.
00:27Because meltwater contains no salt, it weighs less than ocean water and rises up the front
00:33of the glacier in what scientists call a plume.
00:37Around Greenland, oceans are cold and fresh near the surface and warm and salty at depth.
00:42As the plume rises, it draws in the warm, salty water melting the glacier face from the bottom
00:48up.
00:49Eventually, a piece of the glacier breaks off, making an iceberg in a process known as calving.
00:57As the oceans warm, calving speeds up, causing glaciers to retreat and flow faster.
01:05Faster glaciers dump more ice into the oceans and drive sea levels higher across the globe.

01:25You'll see.
01:26We have had the other boats.
01:27Do you see.
01:28give him a Shar the plan,
01:28go for thosebenstreet.com.
01:29You'll see that many other boats.
01:29I hope to do that Когда some planes and跑 before the glacier, let them think about.
01:30From there I will take it for 65 men to 4 and a year.
01:30You'll see that there will be the nicest horizontally another worker.
01:32In that there's no wonder we have a place for the anc approach on this barrier.
