10 de abr. de 2023 · ENVIRONMENT. EXPLAINER. 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...
As part of this effort, the IPCC surveys and distills the scientific literature and provides consensus projections on future sea levels across the globe under a range of possible future scenarios. The NASA Sea Level Projection Tool allows users to visualize and download the sea level projection data from the IPCC 6th Assessment Report (AR6).
19 de abr. de 2022 · In 2022, global average sea level set a new record high—101.2 mm (4 inches) above 1993 levels. The rate of global sea level rise is accelerating: it has more than doubled from 0.06 inches (1.4 millimeters) per year throughout most of the twentieth century to 0.14 inches (3.6 millimeters) per year from 2006–2015.
Climate Tools. Visualize and access information and data relevant to understanding and planning for sea level rise in response to ongoing climate change. Interagency Sea Level Rise Scenario Tool. Visualize and download the sea level scenarios from the U.S. Sea Level Rise Interagency Task Force. IPCC AR6 Sea Level Projection Tool.
The global average sea level has risen about 250 millimetres (9.8 in) since 1880. [1] Between 1901 and 2018, average global sea level rose by 15–25 cm (6–10 in), with an increase of 2.3 mm (0.091 in) per year since the 1970. [2] : 1216 This is faster than it ever rose over the past 3,000 years, if not longer.
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.
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.
