The global average sea level has risen about 250 millimetres (9.8 in) since 1880. [1] The visualization is based on data collected from the TOPEX/Poseidon, Jason-1, Jason-2, and Jason-3 satellites. Blue regions are where sea level has gone down, and orange/red regions are where sea level has risen.
Apr 19, 2022 · Global average sea level has risen 8–9 inches (21–24 centimeters) since 1880. In 2022, global average sea level set a new record high—101.2 mm (4 inches) above 1993 levels.
Sea level rise is caused primarily by two factors related to global warming: the added water from melting ice sheets and glaciers, and the expansion of seawater as it warms. The first graph tracks the change in global sea level since 1993, as observed by satellites.
Yes, sea level is rising at an increasing rate. With continued ocean and atmospheric warming, sea levels will likely rise for many centuries at rates higher than that of the current century.
Visualize and download global and local sea level projections from the Intergovernmental Panel on Climate Change Sixth Assessment Report.
Aug 10, 2022 · Scientists have found that global mean sea level—shown in the line plot above and below—has risen 10.1 centimeters (3.98 inches) since 1992. Over the past 140 years, satellites and tide gauges together show that global sea level has risen 21 to 24 centimeters (8 to 9 inches).
Apr 10, 2023 · Every year, the sea rises another .13 inches (3.2 mm.) Research published in February 2022 shows that sea level rise is accelerating and projected to rise by a foot by 2050.
Aug 10, 2017 · Global sea level is rising from two primary causes: the expansion of ocean water as it warms; and increased melting of land-based ice, like glaciers and ice sheets in Greenland and Antarctica and other “upland” areas.
Chart the changes in Earth’s water and ice that most clearly reveal global sea level rise. Learn more about the different causes of sea level change and the scientific background of observations and projecting sea level.
Mar 21, 2024 · Global average sea level rose by about 0.3 inches (0.76 centimeters) from 2022 to 2023, a relatively large jump due mostly to a warming climate and the development of a strong El Niño. The total rise is equivalent to draining a quarter of Lake Superior into the ocean over the course of a year.
