Sea level - Wikipedia
Mean sea level (MSL, often shortened to sea level) is an average surface level of one or more among Earth's coastal bodies of water from which heights such as elevation may be measured.
Sea level | Rising Tide, Climate Change & Global Warming
2024年11月28日 · Sea level, position of the air-sea interface, to which all terrestrial elevations and submarine depths are referred. The sea level constantly changes at every locality with the changes in tides, atmospheric pressure, and wind conditions.
NASA Sea Level Change Portal
Visualize and access information and data relevant to understanding and planning for sea level rise in response to ongoing climate change. Visualize and download the sea level scenarios from the U.S. Sea Level Rise Interagency Task Force.
Sea Level - Climate Change: Vital Signs of the Planet
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.
Climate Change: Global Sea Level - NOAA Climate.gov
2023年8月22日 · 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.
Overview | Understanding Sea Level - NASA Sea Level Change …
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.
Sea Level 101: What Determines the Level of the Sea?
2020年6月3日 · When it comes to sea level, NASA does much more than just measure it; they also seek to understand it. But for non-scientists, fathoming the forces that determine sea levels around the world can sometimes be a bit daunting, so here’s a little guide to some of the basics.
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.
Is sea level rising? - NOAA's National Ocean Service
Sea level rise at specific locations may be more or less than the global average due to many local factors: subsidence, upstream flood control, erosion, regional ocean currents, variations in land height, and whether the land is still rebounding from the compressive weight of Ice Age glaciers.
Tracking 30 Years of Sea Level Rise - NASA Earth Observatory
2022年8月10日 · 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 …
