Antarctica Ice on the Rise
The American space agency NASA has recently found out that Antarctica's ice sheet is growing. Satellite images show that between 1992 and 2001 ice on the southernmost continent grew at a rate of 112 billion tons a year. After that the ice sheets still became bigger, but at a slower pace.
The new discovery comes at a time when many scientists claim that, due to global warming, the ice on Earth is melting away. In another discovery, scientists have found out that some parts of Antarctica are becoming higher, but they say this is because of more snowfall in the area.
According to NASA, global warming has led to rising temperatures, thus making it possible for more snow to fall on the continent. As a result the snow becomes more compact and eventually turns into ice. In the future NASA hopes to measure ice thickness more exactly when they plan to launch new satellites into space by 2018.
