1
The worlds glaciers are disappearingfaster than scientists thought, with twothirdsof them projected to melt out of existenceby the end of the century at currentclimate change trends, according to anew study.
2
But if the world can limit future warming to just a few more tenths of a degree and fulfilinternational goals—technically possible but unlikely according to many scientists—then slightly less than half the globe's glaciers will disappear.
3
On the other hand, 83 percent of the worlds glaciers would be likely to disappear bythe year 2100 if global temperatures increased even more than the current rate ofwarming.
4
That would increase sea level by 11.5 cm in addition to seas already getting larger frommelting ice sheets and warmer water, said study lead author Dr David Rounce, fromCarnegie Mellon University in the US.“We're going to lose a lot of glaciers,”said DrRounce, a glaciologist and engineering professor.“But we have the ability to make adifference by limiting how many glaciers we lose.”
5
Study co?author Regine Hock, a glaciologist at the University of Alaska Fairbanks in the US and the University of Oslo in Norway, said that“for many small glaciers it is toolate”.“However, globally our results clearly show that every degree of global temperaturesmatters to keep as much ice as possible locked up in the glaciers,”ProfessorHock said.
6
The study projected ice loss by 2100 would range from 38.7 trillion metric tons to 64.4trillion metric tons, depending on how much the globe warmed and how much coal, oiland gas would be burned.
7
The study calculated that all of that melting ice would add anywhere from 9 cm in thebest case to 16.6 cm in the worst case to the worlds sea level. That is 4 percent to 14percent more than previous projections.
8
The study represents significant advances in projecting how the worlds glaciers maychange over the next 80 years due to human‑created climate change.

Ⅰ. Difficult sentence in the text
The study projected ice loss by 2100 would range from 38.7 trillion metric tons to 64.4trillion metric tons, depending on how much the globe warmed and how much coal, oil andgas would be burned. 该研究预测,到2100年,冰损失将在38.7万亿公吨至64.4万亿公吨之间,具体取决于全球变暖的程度以及燃烧的煤炭、石油和天然气的量。
【点石成金】本句是一个主从复合句,ice loss by 2100 would range from...64.4 trillionmetric tons是省略了引导词that的宾语从句,depending on...burned是现在分词短语作伴随状语,how much引导的是一个宾语从句。
