How Do We Measure Sea Level? - NASA Science
Scientists think about sea level in two different ways. The local sea level is what the sea level is at a specific place compared to the height of the land.

Sea Level Rise
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

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
