Blog post: Greenland’s Melting Glaciers
Greenland is the world’s biggest island and is the home to the biggest and only ice sheet on the northern hemisphere. This island and its remote glaciers are being affected by the warming ocean waters due to Global Warming.
Beneath the white surface of Greenland, rivers of ice flow into the ocean. The glaciers on the island’s warmer coast shed kilometers of ice in the sea each year as they are affected by the warm ocean waters. But the giant ice sheet and glacier in the remote northern area of the island that are being affected by warm waters are melting at a much faster rate and has the potential to greatly affect rising sea levels.
Before 2012, they found, that the ice melting was stable, because the glacier was firmly anchored to the sea floor. But since then due to warm ocean waters the glacier has been under-mined and has begun to detach it from the sill. Recently NASA began a project—called the Oceans Melting Greenland (OMG) study which uses underwater probes to measure seawater temperatures around the coastline and airplanes measure the shape of the glaciers. This study will aid in determining how warming ocean waters are eating away at the island’s fringe of ice and what effects they will have.
Global warming is a global issue that must be confronted head-on and changes must be taken to stop its disastrous effects. If changes are not made, and the glaciers continue to melt the effects of the rise in sea levels will be devastating for coastal habitats. We are all affected by Global Warning and we must all join together to bring change to the world.
