  cold

  High latitude
• what happens at the tropics?

  warm water can hold less carbon so diffusion into the atmosphere occurs
• what happens at the Poles?

  the water cools and therefore absorbs CO2 from the atmosphere
• what do deep ocean currents do?

  take the water and carbon back towards tropics
• which water dissolves more CO2: warm or cold water?
