Study: Rising seas slowed by increasing water on land

The article “Study: Rising seas slowed by increasing water on land” was a study released by NASA on how liquid storage’s on land affect the rate of sea level rise.

The study began its origin in Pasadena, California with NASA’s Jet Propulsion Laboratory. The data was collected using NASA’s satellite. What the scientist found was that Earth’s continents were soaking up 3.2 trillion tons of water in its lakes, soils and underground aquifers. This means that rising sea levels are actually decreasing by 20%. Another way this phenomenon is observed is by looking at the water cycle or hydrologic cycle. There have been persistent regional changes within soil moisture and lake level which indicate that the Earth is absorbing more water than the melting rate of the ice sheets and glaciers. This has not been scientifically proven yet with definite numerical values but scientist at NASA believe this adds to the lack of sea level rise.

The article also goes in depth about a second study that was done in 2002 with NASA’s Gravity Recovery and Climate experiment sector. They had twin satellites that provided the scientist with a distance between the two satellites that could help with quantifying land liquid storage trends. Also, it provides data with Earth’s gravitational pull that can estimate the amount of water on Earth’s surface. With these two studies, it is clear to NASA that at this point in time Earth’s continents are slowing down the rising of sea levels.
