ISLAMABAD – Sea levels worldwide are rising faster than predicted as a result of climate change, NASA scientists said. According to the latest satellite measurements from NASA and its partners, seas around the world have risen an average of nearly 3 inches since 1992, with some locations rising more than 9 inches due to natural variation. What’s more worrying is that scientists said an unavoidable sea level rise of at least several feet is coming, The Guardian reported. At a news conference, NASA officials described a new computer visualisation of sea level change incorporating data collected by satellites since 1992, which reveals changes are anything but uniform around the globe. This video by NASA tells about the causes of sea level rise and how sea level has changed over the last two decades as observed by the Jason series of satellite missions.
