Draft:Why Glaciers are Melting

Why are glaciers melting? As the planet warms, glaciers melt causing sea levels to rise but not all of that melt happens on the surface. In the summertime, rivers and pools of meltwater find their way down through the glacier to the bed below. From there, the water runs beneath the glacier until it reaches the ocean because meltwater contains no salt it weighs less than ocean water and rises the front of the glacier in what scientists call a plume.

Around Greenland, oceans are cold and fresh near the surface and warm and salty at depth. As the plume rises, it draws in the warm, salty water melting the glacier face from the bottom up. Eventually, a piece of the glacier breaks off making an iceberg in a process known as calving. As the oceans warm calving speeds up, causing glaciers to retreat and flow faster. Faster glaciers dump more ice into the oceans and drive sea levels higher across the globe

Fun fact: The sheet of ice that covers Greenland contains enough frozen water to raise oceans by 25 feet across the globe!

That's all thank you for reading this!
