Topic 1e - Sea level rise (part 2): altimetry in more depth
Altimetry has been measuring the sea levels, over all the oceans since the early 1990s.
By averaging these levels over the oceans, and looking at the variations on the whole period, one can estimate the global sea level rise with an accuracy of 0.5 mm/yr.
Sea levels across the globe are on the rise due to global climate change, and even a small, permanent increase in the global sea level could have major consequences for the Earth’s populations - particularly for those situated in coastal regions.
Sea level is one of the Essential Climate Variables, and an indicator closely monitored by the IPCC.
