Mapping Global Sea Level Rise: New Gravity Data Help Provide More Accurate Predictions

Source: European Commission, Environment DG

Research from the US helps paint a clearer picture of the extent of global sea level rise, by considering new satellite data on the Earth’s gravity. Its findings support reports of accelerating ice melt and suggest that most of the change in sea levels is caused by receding polar ice sheets and mountain glaciers.

One of the most important factors in monitoring the global climate is measuring global sea level change. This is a complex endeavour and developing a model which can accurately assess such sea level rise (SLR) is challenging. Information to help us estimate SLR comes from a variety of sources, including different types of satellite data and measurements taken by ocean floats, and estimates naturally vary depending on which sources are used.
