A warming planet may lead to swifter ice loss on Greenland’s ice sheet, and faster sea level rise for the rest of the world than previously predicted, scientists said Monday.

Two separate international studies raised concern about the pace of ice melt on the world’s second largest ice sheet after Antarctica, and suggested that scientists may have underestimated the variable behavior of Greenland’s ice.

Can We Save Our Cities from Drowning?

Over the next 200 years, the ocean is expected to rise 10 feet, putting many major cities worldwide underwater.

“The current models do not address this complexity,” said Beata Csatho, an associate professor of geology at the University at Buffalo and lead author of the paper in the Proceedings of the National Academy of Sciences.

Currently, scientists use simulations based on the activity of four glaciers — Jakobshavn, Helheim, Kangerlussuaq and Petermann — to build forecasts of melting into the ocean.

But the new PNAS study used NASA satellite data to look at nearly 100,000 points of elevation and how they changed from 1993 to 2012, painting a much fuller picture of where melting has happened in the past.

Researchers also came up with a new number for how much ice has been lost in recent years on Greenland’s ice sheet. For 2003-2009, the time period with the most accurate data, 243 metric gigatons of ice were lost annually, adding about 0.68 millimeters of water to the oceans each year, said the PNAS study

How do we stop the problem of ice loss? This is one of the problems causing by the global warming,so First we have to think several ways to stop the global warming.In short, it is said that global warming is caused by increasing of greenhouse gases in atmosphere, meteo strike, change og current or surface of the earth, orbit of the earth around sun and so on. In this point, what can we do? Can you decrease a huge amount of greenhouse gase in atmosphere? Can you change the orbit of the earth?

That answer is No.

What should we do to solve this problem? we have a ggod ability.
That ability is adaptions We can adapt to environmental changes using the science techinology such as air conditionar, heat wear and so on. Because we have little ability to change the global warming with big scale, we have to do small effort as possible as we can. In conclusion, it is easier for us to adapt to environmental changes than any other solution for global warming.
