Overview | Understanding Sea Level - NASA Sea Level Change Portal
Find out about the history of measuring sea level and how state-of-the-art physical climate models predict sea level change into the future. We explain the current and projected rates and how they are derived.
Overview | Global Sea Level – NASA Sea Level Change Portal
Global mean sea level provides an integrative measure of the state of the climate system, encompassing both the ocean and cryosphere (ice covered portions of Earth), and it can be viewed as an important indicator of what is happening to the climate in the present and what may happen in the future.
Global Mean Sea Level | Key Indicators - NASA Sea Level Change …
The plot shows global change in sea level since 1993, as observed by satellite altimeters. The black line tracks the measurements, while the blue line shows how much uncertainty is associated with these measurements.
Sea Level Projection Tool – NASA Sea Level Change Portal
Visualize and download global and local sea level projections from the Intergovernmental Panel on Climate Change Sixth Assessment Report.
NASA-led study reveals the causes of sea level rise since 1900
Aug 21, 2020 · To make better predictions about the future impacts of sea level rise, new techniques are being developed to fill gaps in the historic record of sea level measurements. We know the factors that play a role in sea level rise: Melting glaciers and ice sheets add water to the seas, and warmer temperatures cause water to expand.
What causes sea-level rise? – NASA Sea Level Change Portal
Recently, spaceborne instruments have detected accelerations in ice sheet mass losses and sea-level rise, which is expected when the globe warms, based on our understanding of Earth’s history and climate physics. You can read more about what is …
NASA Sea Level Change Portal: By the Numbers
Estimates for global mean sea level rates for two different time periods: 1) the era of satellite observations, and 2) the 20th century. Links to observational time series are also provided where possible. Additional explanations of the processes contributing to sea level change can be found here: Understanding Sea Level.
NASA Data Helps International Community Prepare for Sea Level …
Nov 14, 2024 · The agency’s global data is now available in the sea level section of the Earth Information Center. NASA developed the global sea level change website in collaboration with the U.S. Department of Defense, the World Bank, the U.S. Department of State, and the United Nations Development Programme.
Track Sea-level Changes Anywhere with NASA's New SEA Tool
Nov 4, 2021 · You can check “total” sea-level change for points around the globe, or just the contribution from ice-melt and the water cycle, from ocean variation from region to region, or from ground movement.
