A new scientific study has concluded that two-thirds of the world's glaciers are on the way to disappearing by the end of the 21st century under current climate change trends.
The study, published Thursday in the journal "Science", analyzed all the 215,000 glaciers in the world.
It concluded that these glaciers are melting faster than scientists thought. But how quickly they melt depends on how much the planet warms.
The authors of the study explained that it is no longer possible to act to save many small glaciers, because it is already too late.
The new study predicts that global warming will cause between 38 and 64 trillion metric tons of ice to melt between now and the end of the century, adding 3.5 to 6.5 inches to sea levels.
