The latest research report shows that with the large number of human activities release greenhouse gases will lead to the Antarctic ice sheet melted completely, and finally to the world's many large cities were submerged.
Currently, scientists warned that if humanity is still available to do everything possible to burn fossil fuels, most of the world's most densely populated large cities will be submerged. These cities include: London, New York, Tokyo, Hong Kong and Shanghai.
Human burning of oil, gas and coal will release large amounts of carbon dioxide, causing the Antarctic ice sheet melted completely, sea levels appear destructive rise. Although the focus of the West Antarctic ice sheet was the most climate change research, but the latest research report shows that East Antarctica ice sheet is also on the verge of melting.
The study co-author Professor Anders Levermann said that if we want to be able to Tokyo, Hong Kong, Shanghai, Calcutta, Hamburg and New York and other cities still continue to develop, we must avoid the east Antarctic ice sheet melted.
The study concluded that carbon emissions can not be compromised is causing sea level rise, threatening the Antarctic ice sheet as a whole. If we burn all fossil fuel resources currently available, the future of Antarctica will become completely ice-covered ocean.
Unlimited future emissions of carbon dioxide gas, Antarctic sea levels will rise sharply, coming in 1000 will rise by tens of meters, eventually leading global ice caps melt. Levermann colleague Ken Caldeira said: "It is not clear whether this dynamic ice sheet melting can be reversed, and if so, how long it takes to reverse based on the current human way of life, we can not stop using fossil fuels. prevent the release of carbon dioxide into the atmosphere. If we can not stop the release of carbon dioxide into the air, some of the hundreds of millions of people's lives to accommodate a total of more than megacities future sank one day. "
Earlier this year, scientists warned that the world must be prepared to rapid climate change preparations. This study shows that by 2020, the northern hemisphere temperatures rise 0.25 degrees Celsius per decade, the increased rate of at least the last 1,000 years, has not been seen.
It is reported that the study was funded by the Pacific Northwest National Laboratory researcher responsible, they focus on climate change, a 40-year period, in general, due to the increase in greenhouse gas emissions from human activities, thereby trapping the sun's heat becomes more global warm.
