Melting of the north polar ice cap has resulted in an increase in sea level of 20 cm since 1880.

Question

Quizplus · Accepted Answer

The melting of the north polar ice cap (Arctic sea ice) contributes minimally to sea level rise directly because it is already floating on water, and its melting does not significantly increase the volume of water. The 20 cm rise in sea level since 1880 is primarily attributed to the melting of land-based ice (such as glaciers and ice sheets) and thermal expansion of seawater.
