In addition to raising sea water levels, widespread loss of glaciers will likely alter climate patterns in other, complex ways. It is as simple as that. The Bering Glacier, as a result of its immense weight, is responsible for the stabilization of the Pacific plate which lies underneath the North American plate. This is not a good thing for humans and animals that depend on these water sources for drinking water. Glaciers form over a period of a few hundred years, but some glaciers are many thousands of years old. As the situation worsens due to global warming, this might be a consideration, and scientists, inventors, and technologists might begin to find ways of doing that. About 80% of Greenland is covered by an ice sheet – 660 square miles. Glaciers form on land and are not stagnant – they move. Increasing droughts together with industrial poisoning of our water by numerous manufacturers and commercial interests, there is less and less potable water available to drink. Glaciers are important indicators of global warming and climate change in several ways. 10% of the Earth is Covered with Glaciers. That said, with the exception of Australia, every continent contains glaciers. Glaciers are a vital part of our world. This is what the German language online Die Presse writes here. A glacier doesn’t melt slowly and steadily like an ice cube on a table. Rising sea levels do not get evenly distributed throughout the planet. The Taylor Glacier in Alaska is also known as the Blood Falls glacier because it spews out a red liquid in spring. This process is called basal sliding. If they melted, because they contain 90% of the world’s fresh water, the seas would rise by between 230 and 260 feet. Our way of life is based on climate as we know it. Cirque glaciers form on the slopes and crests of mountains. The elephant in the room is that if the glaciers melt, then all that fresh water will go into the sea. Sea levels may actually go down in some regions, but rising sea levels will be a critical issue in many other parts of the planet, adversely affecting billions of people in India, Bangladesh and China as well as along the U.S. Gulf and Northwest coasts. As these glaciers contain more water (69%) than all the earth’s rivers and lakes together (.3%) it is a tempting thought that we might be able to ferry water from icebergs to different countries. :). Glaciers form in very cold climates where new snow falling on top of old snow eventually makes the snow underneath compress into ice. Surging happens when meltwater underneath the glacier makes the glacier move faster than usual. When glaciers melt, darker exposed surfaces absorb and release heat, raising temperatures… Antarctica has the largest ice sheets in the world and comprises 90% of all ice. In 2012, it moved 150 feet per day causing great concern. These rivers and lakes are the source of drinking water for many people and animals. Support the Extreme Ice Survey by checking out our store! Anonymous. Until 2017, scientists believed that while the glaciers would melt due to climate change, they thought it was a slow process. Ice shelves are part of an ice sheet that extend into the water. Ice streams are part of an ice sheet that are narrow and move faster than the ice sheet. Thanks for the information. They eat algae and pollen during the summer months and bury themselves deep in the ice during the winter. Glaciers are important to life on earth. Relevance. It is estimated that the meltwater will heighten the sea by 260 feet. An ice cap is a small glacier that form in the valley of a mountain range. Water not only expands when frozen, but also when heated, and it is estimated that in the 21st century the melting of ice caps and glaciers combined with the thermal expansion of ocean water will cause an average increase of sea level of roughly a meter (a bit more than one yard). I do know that they are melting more rapidly in recent years. They are the most visible evidence of global warming today. Answer Save. will all die. Melting ice is changing the way seas influence climate on a global scale. Once glacial ice begins to break down, the interaction of meltwater and sea water with the glacier’s structure can cause increasingly fast melting and retreat. They look very much like a small earthworm and are about half an inch long. Ice that took centuries to develop can vanish in just a few years. Academics and school groups from around the world recognize our state as one of the most important areas to view and learn about the last glacial period—the features are that distinct. As all of life in the sea can only exist in a saline environment, fish seaweed, mammals, etc. The melting fresh water from glaciers alters the ocean, not only by directly contributing to the global sea level rise, but also because it pushes down the heavier salt water, thereby changing what scientists call the THC, or Thermo (heat) Haline (salt) Circulation, meaning currents in the ocean. Greenland, Iceland, Canada, Russia, and Alaska have part of their land in the Artic. 5 points Name312 Asked 11/11/2019. Log in. Click the poster image below. Recent evidence has indicated that a melt can take place very rapidly as this is now happening in Anarctica.
