Sea-Level Rise Measurement

Sea-level rise measurement involves assessing how much ocean levels increase over time, primarily due to climate change. This is done using tide gauges that measure water levels along coastlines and satellite altimetry, which uses radar to measure the height of the ocean from space. Factors contributing to rising sea levels include melting glaciers and ice sheets, as well as the expansion of seawater as it warms. Accurate measurements are crucial for understanding the impact on coastal communities and ecosystems, aiding in planning and adaptation efforts to mitigate the effects of climate change.
