19 de abr. de 2022 · Global mean sea level has risen about 8–9 inches (21–24 centimeters) since 1880. The rising water level is mostly due to a combination of melt water from glaciers and ice sheets and thermal expansion of seawater as it warms.
The NASA Sea Level Projection Tool allows users to visualize and download the sea level projection data from the IPCC 6th Assessment Report (AR6). The goal of this tool is to provide easy and improved access and visualization to the consensus projections found in the report.
10 de abr. de 2023 · Sea levels are rising at an extraordinary pace. Here's what to know. Seas are predicted to rise a foot by 2050, regardless of how much global carbon emissions can be reduced.
Visualize and access information and data relevant to understanding and planning for sea level rise in response to ongoing climate change.
Sea level rise would slow down between 2050 and 2100 if there are very deep cuts in emissions. It could then reach slightly over 30 cm (1 ft) from now by 2100. With high emissions it would accelerate. It could rise by 1.01 m (3 + 1 ⁄ 3 ft) or even 1.6 m (5 + 1 ⁄ 3 ft) by then.
How much has the sea level risen due to climate change and what are the impacts and projections for the future? Find out in this comprehensive report by the IPCC, the leading international body for the assessment of climate science. Learn about the causes, effects and uncertainties of sea level rise and its implications for coastal communities and ecosystems.
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.
