해수면 변화는 육빙의 녹음으로 인한 강물의 유출입, 강수와 증발, 해류의 수렴과 발산, 해수의 열팽창 등이 영향을 끼친다.
Sea level changes are affected by river inflow and outflow, precipitation and evaporation, convergence and divergence of ocean currents, and thermal expansion of seawater due to the recording of land ice.
A1B는 약 30cm, B1은 약 22cm 상승 하는 것으로 분석이 되었다. 이는 각각의 시나리오에 합당하는 결과로 분석되고, CO2를 증가시키는 연료의 사용량이 늘 어나게 되면 해수면 상승에 어떠한 영향을 끼치게 될지 보여 주는 결과이다(Figure. 7).
It was analyzed that A1B rises by about 30 cm and B1 rises by about 22 cm. This is analyzed as a suitable result for each scenario, and shows how increasing the use of fuel to increase CO2 will affect sea level rise (Figure 7).
Worldwide, most glaciers are shrinking or disappearing altogether. Relative to 1970, the climate reference glaciers tracked by the World Glacier Monitoring Service have lost a volume of ice equivalent to nearly 25 meters of liquid water—the equivalent of slicing 27.5 meters of ice off the top of each glacier.
- Melting of mountain glaciers and ice caps, and melting and outflow of the ice sheets in Greenland and Antarctica.
- Greenland Ice Sheet and West Antarctic Ice Sheet contain ice equivalent to about 7m and 3-5m sea level rise, respectively. Thus, the behavior of these ice sheets has a major influence on future sea-level rise.

Pedersen Glacier, at Aialik Bay in Alaska’s Kenai Mountains, in 1917 (left) and 2005 (right). In the early 20th century, the glacier met the water and calved icebergs into a marginal lake near the bay. By 2005, the glacier had retreated, leaving behind sediment allowed the lake to be transformed into a small grassland. Photos courtesy of Louis H. Pedersen (1917) and Bruce F. Molina (2005), obtained from the Glacier Photograph Collection, Boulder, Colorado USA: National Snow and Ice Data Center/World Data Center for Glaciology.
