Due lacks of source, I consider kokonut's post as his opinion or myth.
I learned from science teacher in 4 years ago and asked about how sea level is rise so when sea ice is melting, regardless on how size of ice. It maybe not worse as Antarctica but melting of sea ice in Arctic is still result in sea level rise and it doesn't mention about how is worse.
Speaking of ice cubes in cup, they are nothing to compare with ice because ice in Arctic and Antarctica are very larger.
