How DNA Could Unlock the Mysteries of Melting Glaciers and Ice SheetsAnnie Sneed
【题目】The ice sheets in the poles and glaciers on the high mountains are melting and the world is in danger of 1.While you are surprised by the special 2, you know that it is just a made up story and there will be a hero to save the world. But what if the ice sheets are ...
of the ice, which increases the abortion of heat and in turn increase the rate of the melting, and creates moulins, result in the ice sheets to melt from its base.In 2019,glaciers and ice sheets are already being darkened by dust, the albedo would further reduced, accelerate ice melting....
完形填空The ice sheets in the poles and glaciers on the high mountains are melting. So the world is indanger of 1 . While you were surprised by the special 2 ,you know that it is just a made-upstory and there will be a hero to save the world. But what if the ice sheets are re...
Ice sheets are constantly in motion, slowly flowing downhill under their own weight. Near the coast, most of the ice moves through relatively fast-moving outlets called ice streams, glaciers, and ice shelves. As long as an ice sheet accumulates the same mass of snow as it loses to the se...
The use of such techniques to preserve ice sheets is not new. Since the early 21st century, an increasing number of countries, including Austria, France, Germany, Italy, and Switzerland, have started to protect glaciers...
That's because glaciers contain fresh water, which takes up more volume than salty ocean water [source: Huang]. However, their impact is small compared to the melting of Antarctic ice sheets. The Polar Ice Caps The main ice-covered landmass on Earth is Antarctica at the South Pole, with...
(direct). As glaciers and ice sheets melt, they add more water to the ocean. Increasing rates of global warming have accelerated (加速) Greenland's ice mass loss from 25 billion tons per year in the 1990s 63. a current average of 234 billion tons per year, 64. means that Greenland'...
Sea level rise is caused by warming of the ocean and melting from glaciers and ice sheets. The research, based on 25 years of satellite data, shows that pace has quickened, mainly from the melting of massive ice sheets. It confirms scientists' computer simulations and is in line with predic...
"This is going to cause additional sea level rise. We are watching the ice sheet hit a tipping point." Scientists already understood Greenland to be one of the biggest contributors to sea-level rise due to its glaciers and ice sheets which cover 80% of its surface. ...
