This amazing image of Baffin Bay, snapped back on July 17, 2005, shows a large number of icebergs floating off the coasts of Greenland. It highlights the devastating effects that global warming and climate change can have on Earth's sea levels, scientists say.

The amazing image was collected by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument on the NASA Terra satellite, which compiles false-color images at infrared, red and green instruments.

Greenland is the second-vastest repository of ice and freshwater on Earth, preceded only by Antarctica. If its ices were to melt, sea levels around the world would increase by at least 7 meters (23 feet). As such, experts are constantly monitoring its health status.

In addition, icebergs originating in Baffin Bay can pose a hazard for navigation in the North Atlantic. Satellite data are used to keep track of the largest ones, and relay warnings to ship commanders in the affected areas.
