22 - Sea Level Rise

22 Source: IPCC An extreme but not impossible scenario 19.7 ‘’ ( 50 cm) 31.5‘’ (80 cm) 7.9‘’ (20 cm) Global mean sea level rise from 1901 Rising Sea Levels
Set 1 www.climatefresk.org Since 1900, sea levels have risen by 7.9'' (20 cm). This is caused by the thermal expansion of ocean waters and the melting of glaciers and ice sheets. 22

Causes

Melting of Glaciers

Melting of Glaciers

A melting of 100 gigatons of ice per year is equivalent to about 0.28 mm per year of mean sea level rise. Thus, 15 to 35% of sea level rise is linked to the melting of glaciers, according the IPCC scenarios. 30% to 35% is linked to the expansion of water. The remainder is linked to the melting of the ice caps.

No, more rain is not going to cause the oceans to overflow! This is a rare mistake to be made, but if it happens to you, ask the players where rainclouds come from...
