# How much energy would be required to actively reduce the temperature of the oceans of Earth by 1℃?

Is there a way to calculate the energy required to reduce the heat of oceans?

Am I wrong in thinking it is not as simple as reversing the calculation for specific heat of sea water?

• it is literally as simple as calculating hte specific heat of seawater unless you are trying to coll it in some specific manor. – John Apr 19 '19 at 15:35
• Thanks - so the calculation would just be specific heat x mass of the oceans? I.e. the energy to raise by 1 degree is equal to the energy to reduce by 1 degree? – the4thv Apr 19 '19 at 15:54
• Note the very significant difference between the energy you need to extract from the ocean to cool it by 1°C and the energy required to extract that energy. In a similar way the energy used by a fridge to cool the food inside it is MUCH more than the energy actually extracted from the food, – Camilo Rada Apr 19 '19 at 19:38
• as your question is now it is a little theoretical so in real life you will need a plan for where you are going to dump the heat and that is the hard part of this(in the light of your tag climate-change) – trond hansen Apr 20 '19 at 5:32
• @trondhansen, my thoughts exactly and this is where I'm going with this line of thought; we can store it in a manner that we can later utilize it, or somehow 'vent' it to outerspace. Two immediate ideas: 1) Using a form of evaporation and salt storage (en.m.wikipedia.org/wiki/…). 2) Using the upper atmosphere to cool bodies of water by cooling something high up and then placing it in the ocean, kind of like a man made ice cube. I currently can't see how either might work at scale or what that scale would need to be. – the4thv Apr 20 '19 at 14:32
