How does climate change affect the ocean ecosystem? climate change causes waves to be smaller in the northern hemisphere and larger in the southern hemisphere. climate change causes ocean currents to stop in the northern hemisphere and in the southern hemisphere. climate change increases temperatures in the ocean. climate change decreases temperatures in the ocean.

Typically currants flow clock wisein northern hemisphere and counter clockwise in the southern hemisphere. ocean currants transport cold water from the poles and back to the tropics and visa versa.  currants regulate the global climate with out currants temps would be unbareable super hot at the equator and too fridged at the poles. making much less of earth land liveable for us. 

climate change increases temps in the ocean
