For over 20 years, satellite altimeters have measured the sea surface height of our ever-changing oceans. This series of images shows the complicated patterns of rising and falling ocean levels across the globe from 1993 to 2015. Sea levels reflect changing currents (which tilt the sea surface), the redistribution of heat (which makes sea levels higher) and the long term rise in global sea levels that is the result of human-caused warming. The globally averaged rise is traced out in the bottom r

For over 20 years NASA has been tracking the global surface topography of the Ocean in order to understand the important role it plays in our daily lives. Climate change is causing our ocean to warm and glaciers to melt, resulting in sea level rise. Since 1880, the global sea level has risen 8 inches; By 2100, it is projected to rise another 1 to 4 feet. :::LEARN MORE::: Key Indicators: Sea Level http://climate.nasa.gov/key_indicators/#seaLevel National Climate Assessment: Sea Level Rise http://

Sea level update 🌊 Global average sea level rose by about 0.3 inches (0.76 centimeters) from 2022 to 2023, according to a @NASA-led analysis. This relatively large jump is due mostly to a warming climate and the development of a strong El Niño. With more than 30 years of satellite observations, the data show that global average sea level has risen about 4 inches (9.4 centimeters) since 1993 and the rate of increase has more than doubled. “Current rates of acceleration mean that we are on track

Sea level rise is one significant effect of the changing climate on Earth. A new study using NASA satellite data shows the rate of global sea level rise has been accelerating in recent decades, rather than increasing steadily. The upshot? Globally, sea levels could rise 26 inches by 2100. That's enough to cause problems for coastal cities around the planet. A warming climate raises sea level in two ways. First, warmer water expands as it heats up, which has contributed about half of the sea leve
