Melting Ice Sheets

Melting Ice Sheets

Freshwater coming from the melting of Greenland may threaten the thermohaline circulation.

3
Consequences

Carbon Sinks

Weakening Gulf Stream

CO2 is absorbed at the surface of the ocean. Thermohaline circulation helps mix watersurface and deep ocean which is essential to the absoption of CO2 by the ocean.
Energy Budget

Weakening Gulf Stream

Heat is absorbed at the surface of the ocean. Thermohaline circulation helps mix watersurface and deep ocean which is essential to the absoption of energy by the ocean.
Disruption of the Water Cycle

Weakening Gulf Stream

Weakening of thermohaline circulation may disrupt water cycle even more in many places in the word.
