Could Building Massive Seafloor Barriers Around Antarctica Help Slow Sea Level Rise?

In a new peer-reviewed research published in the "Frozen Circle" magazine, two scientists said the large-scale earth engineering project will help prevent the collapse of the southwestern ice sheets and along the coastal walls and pier Including construction. The sea level of the world rises slowly.

Michael Wolovick, Earth Scientist at Princeton University and John Moore, a climate scientist at Beijing Normal University, pointed out that various physical barriers, the most sensitive glaciers in glaciers, prevent melting of glaciers and hot water I have studied ways to prevent reaching the bottom of the body. They concentrated the model on the Florida - sized Thwaites glacier. And it is expected to be one of the broadest glaciers in the world - from 50 to 60 miles - and future single sea level rise, single maximum source up to 10 feet in the world

Researchers have found that the possibility of preventing the ice crown on the west coast from being runaway is 30% in the near future by constructing sands, gravels, or gravel pillars dispersed 1000 feet in length on the ocean floor I found out. A more ambitious project - making a continuous small wall along the edge of the glacier - blocks about 50% of the warm water reaching the ice and it is likely to prevent the collapse of the runaway ice cap in the next 1000 years There is a possibility of%.

"The most important result of our research is that meaningful ice sheet intervention is roughly within the size of human rational achievement," Wolovick said in a statement.

But Wolovick and Moore warn that what they call the "Glacier Earth Project" project will be very expensive and time-consuming, Antarctica is one of the worst environments on Earth. Submarine barriers may help slowly melt from below, but they are helpless because of the warm air that melts the ice from above.

Scientists also insist that glacial geoengineering is not a substitute for dramatically reducing global greenhouse gas emissions. Scientists say in a statement: "There is a fraudulent factor in society to use our research to oppose the necessity of reducing emissions." The more carbon that is emitted, the less likely the ice cap will survive the long-term survival as it approaches existing quantities. "

Scientists predict that the world sea level will rise by melting two huge ice sheets on Antarctica and Greenland, especially the east coast of the United States of America. However, many countries in the world are affected by sea level rise, which can lead to the evacuation of millions of people. As a result of sea level rise, the Maldives are already looking for new homes. "So far scientists have come up with the strongest evidence that global warming greatly increases the intensity of the most extreme storm in the world.The research published in the journal this week, the strongest since 1981 The maximum wind speed of the tropical cyclone is rising sharply, it is unlikely that the rising trend caused by the rise in the seawater temperature will soon stop. "

Much of this article focuses on sea level rise in this century. However, sea level rise may exceed this level. In early May, two studies discovered that the huge ice sheet of Western Antarctica is destined to collapse in the next century. This process will not last for another 200 to 900 years, but it can place most of the float at 13 feet above sea level - under the water. In Dot Earth, Andrew Revkin discussed various experts and how future generations should deal with sea level rise.

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 to 6 feet long enough to flood Florida Everglades, and most of the coastal cities like 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.
