Satellite data are based solely on measured sea level, while the long-term tide gauge data include a small correction factor because the size and shape of the oceans are changing slowly over time. (On average, the ocean floor has been gradually sinking since the last Ice Age peak, 20,000 years ago.)
The contribution for the 2012–2016 period was nearly as large as that of Greenland. It was 0.63 mm of sea level rise per year, equivalent to 34% of sea level rise from land ice sources. [127] Glaciers contributed around 40% to sea level rise during the 20th century, with estimates for the 21st century of around 30%. [6]

In the IPCC’s 2021 report, scientists estimated that sea level will rise about 0.9 to 3.3 feet (0.28 to 1.01 meters) by 2100, but also said those numbers didn’t factor in uncertainties around ...
In sharp contrast, the period between 14,300 and 11,100 years ago, which includes the Younger Dryas interval, was an interval of reduced sea level rise at about 6.0–9.9 mm/yr. Meltwater pulse 1C was centered at 8,000 years ago and produced a rise of 6.5 m in less than 140 years, such that sea levels 5000 years ago were around 3m lower than ...
Using peer-reviewed sea level rise projections and local elevation from Climate Central’s models, the findings show compelling visuals that paint a stark contrast between the world as we know it ...
The rate of global sea level rise is speeding up dramatically as temperatures continue to rise due to climate change, a new report finds, and now poses “a major threat to many millions” of ...
English: Observed and projected changes in global mean sea level for 1800–2100. The boxes on the right show the very likely ranges in sea level rise by 2100 (relative to 2000) corresponding to three different RCP scenarios. The lines above the boxes show possible increases based on newer research of the potential contribution to sea level ...
