42 - Metanhydrater

Svækkelse af Golfstrømmen 42
Set 5 www.climatefresk.org 42 Golfstrømmen er en del af den såkaldte Atlanterhavets termohaline cirkulation - et globalt system af varme havstrømme. Smeltevand fra Grøndlands indlandsis kan svække Golfstrømmen, og dermed destabilisere vandets kredsløb yderligere, samt reducere havets evne til at absorbere kulstof og varme.

Metanhydrater

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.

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