The observed increase in sea levels is a consequence of several interacting factors. Thermal expansion, the volumetric increase of water due to warming, is the primary driver. The substantial addition of meltwater from glaciers and ice sheets, exacerbated by climate change, significantly amplifies this effect. Changes in terrestrial water storage, predominantly groundwater depletion, further contribute to the overall increase. The influence of land vertical movement (isostatic adjustments) is regionally significant but less impactful on the global average. These factors act concurrently, leading to the measured rise in global mean sea level.

Rising sea levels, as depicted on maps, are a complex issue stemming from a multitude of factors. Primarily, thermal expansion of water plays a significant role. As the Earth's climate warms, the oceans absorb a substantial amount of heat, causing the water molecules to move more rapidly and occupy a larger volume. This phenomenon, known as thermal expansion, contributes significantly to sea-level rise. Additionally, melting glaciers and ice sheets, particularly in Greenland and Antarctica, contribute massive amounts of freshwater into the oceans, further increasing the overall volume of water. The rate of melting is accelerating due to rising global temperatures. Furthermore, changes in land water storage, such as groundwater depletion from excessive pumping for agriculture and urban use, lead to less water being stored on land, which consequently flows into the oceans. Finally, while less significant compared to the other factors, the vertical movement of the land itself (subsidence and uplift) can influence local sea levels. In essence, a combination of thermal expansion, melting ice, altered land water storage, and land movement collectively contributes to the observable rise in global sea levels illustrated on maps.
