Laser technology aboard aircraft has allowed scientists to measure the Greenland Ice Sheet, one of the largest bodies of ice in the world. Is it growing or shrinking?
- NASA scientists measure the size of Greenland's ice sheet at five year intervals to monitor the effects of global warming.
- Using a laser attached to an airplane, scientists can measure the ice to an accuracy of 10cm.
- Scientists have discovered that the ice sheet's size is decreasing by 100 billion tonnes every year.
- Earth's ice sheets control sea levels and their demise will have dramatic consequences for the future.
Greenland, North America
After Antarctica, the Greenland ice sheet has the largest concentration of fresh water on the planet.
80% of Greenland is covered in ice
A group of NASA scientists have spent over a decade measuring the effects of global warming here in Greenland.
But how do they do it from ...
