> the end of arctic ice
nitpick: it is actually antarctic ice we need to worry about. Arctic ice (except on Greenland) is floating and so it is already displacing its weight in water.
- the_gastropod 10y agoMelting Arctic ice is also worrisome because it alters the salinity of the ocean, potentially altering ocean currents.
- ealloc 10y agoMelting Arctic ice also changes the surface albedo so more solar energy is absorbed, it changes the ocean salinity, and no longer cools the winds above it. Thermal expansion of the ocean contributes almost half of total observed sea level rise. (1.1mm out of 2.8 mm total per year)
