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.

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 …

Explore historical sea level changes and future coastal flooding projections with NOAA's Sea Level Calculator. Search by location, view curated data sets, and make informed adaptation decisions based on tide station or grid-based insights.

calculatedearth shows what our planet looks like at differing sea levels. The first few metres can help visualise the potential effects of localised flooding and perhaps global warming. Above that, it's also a good way to visualise Earth's topography.

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 …

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.

2019年7月8日 · What is sea level and what does sea level actually mean? Discover the meaning of sea level and how rising sea levels can impact our planet.

2023年10月19日 · Sea level is the base level for measuring elevation and depth on Earth. Because the ocean is one continuous body of water, its surface tends to seek the same level throughout the world.

Sealevelmap.io is an interactive map exploring global sea level fluctuations spanning the past 135,000 years. Batchelor, C.L., Margold, M., Krapp, M. et al. The configuration of Northern Hemisphere ice sheets through the Quaternary. Nat Commun 10, 3713 (2019)

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.
