How a massive wall in Antarctica could hold back sea-level rise

The glacier is a powerful glacier that can crush the huge rock behind and crush the valley to a steep mountain.

Most of these ice are in Antarctica and Greenland. Antarctica is 40% more expensive than the United States and covers a thick ice sheet of almost 1 mile, equivalent to about 200 feet above sea level. Most of the ice is currently stable, but the scientists are concerned about the big ice sheet in the southwest. The sea level will rise by about 11 feet and will collapse when it reaches the turning point. An additional 23 feet of sea level is stored in Greenland as ice, which melts at an even faster rate. The rest are glaciers and ice sheets spreading all over the world, and they are usually melting.

Scientists nearly doubled scientists' predictions on sea level rise since Antarctic ice came to melt much faster than before, last month. Thus, by the end of the century the ocean may rise six feet long enough to flood Florida Everglades, and most of the coastal cities such as Norfolk, Charleston and New Orleans are underwater. President Obama 's agreement or policy will help to reduce the CO 2 emissions of trucks, buildings, household appliances, and aircraft, halving the carbon pollution per mile, and doubling the fuel efficiency of a car. The clean energy plan he announced in August last year will help clean dirty power plants, which account for about 40% of China's carbon pollution.
