View Full Version : Discussion: Satellite Measures Rising Seas

2003-Aug-28, 06:42 PM
SUMMARY: The spectre of global warming and rising ocean levels have been a concern for many years, but NASA has some real numbers to help measure the situation. According to the Topex/Poseidon and Jason satellites, sea levels have been rising an average of 2.8 millimetres a year since observations began in 1992. Whether rising sea levels are caused by human impact or a natural cycle still isn't clear, but the impact is already being felt in coastal communities around the world with water inundating low-level areas and an increased rate of beach erosion.
