In less than 25 years, the global sea level has gone up an average of three inches (eighty millimeters), and is rising faster than it was 50 years ago, according to a group of NASA scientists. Yesterday, NASA's Sea Level Change Team shared some of their findings, which includes data on sea levels measured from space using satellites.
Sea level rise isn't evenly distributed around the world. In some areas, the sea has risen as much as 9 inches (23 centimeters), while in other places the sea level has dropped. For example, on the West Coast of the United States sea levels have actually been lower over the past 20 years, due to temporary ocean cycles. But when these cycles end, the impact of climate change is expected to be seen.
NASA predicts that oceans will continue to rise at a considerable rate, about 0.1 inch (3.21 millimeters) per year on average. In 2013, the UN Intergovernmental Panel on Climate Change (IPCC) predicted sea level rise would be between one and four feet (0.3 to 1.2 meters) by the year 2100. NASA's data suggest the higher end of the range.
National Oceanic and Atmospheric Administration (NOAA) has an interactive map to show how sea level rise will affect different regions around the world.
