sea level change

Sea level change refers to the rise or fall of ocean water levels related to various factors. Primarily, it occurs due to climate change—glaciers and ice sheets melting contribute additional water to the oceans, while warmer water expands. Human activities, such as burning fossil fuels, also accelerate these changes. Sea level rise can lead to flooding in coastal areas, erosion, and damage to ecosystems. Conversely, localized changes may occur due to land sinking or uplifting, known as subsidence and uplift. Understanding sea level change is crucial for planning and protecting communities along coastlines.
