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.
Climate Change: Global Sea Level - NOAA Climate.gov
Aug 22, 2023 · Global average sea level has risen 8–9 inches (21–24 centimeters) since 1880. In 2023, global average sea level set a new record high—101.4 mm (3.99 inches) above 1993 levels.
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.

Sea level rise, facts and information - National Geographic
Apr 10, 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.
NOAA Sea Level Rise Portal - NOAA's National Ocean Service
The Interagency Task Force on Sea Level Change co-develops critical science on sea level rise and its related impacts. This interactive site allows users to explore past, present, and projected future sea level rise, associated impacts, and adaptation measures for their area.
How is sea level rise related to climate change? - NOAA's …
Currently, sea level is rising about one-eighth of an inch per year but is projected to rise in the future. By 2100, sea levels may rise another one to eight feet. Sea level can rise by two different mechanisms with respect to climate change.
Sea Level Rise - MIT Climate Portal
May 25, 2021 · Sea levels around the world are rising because of climate change. As humans burn fossil fuels, we release carbon dioxide and other greenhouse gas emissions, which warm the Earth and the oceans. Because water expands as it …
Overview | Understanding Sea Level - NASA Sea Level Change …
Earth’s seas are rising, a direct result of a changing climate. Ocean temperatures are increasing, leading to ocean expansion. And as ice sheets and glaciers melt, they add more water. The globally averaged trend toward rising sea levels masks deeper complexities.
