DescriptionGlobal sea level rise from 1992 to 2020, satellite data chart.svg |
English: The image shows the development of global sea level from 1992 to 2020. Seasonal variations were removed. Measurements have been conducted via satellites TOPEX/Poseidon, Jason-1 and Jason 2. The trend line clearly shows the constant increase in global sea level of 3.5 ± 0.3 mm/year since the 1990s. The raw data is from http://www.cmar.csiro.au/sealevel/sl_hist_last_decades.html . |
