Preliminary study of Global Warming mitigation by grazing OTEC

lobal warming means the observed century-scale rise in the average temperature of the Earth’s climate system. However,
most of the increased heat is stored in the ocean. This causes the sea surface temperature to rise, producing extreme
weather. Ocean Thermal Energy Conversion (OTEC) utilizes the temperature difference between the sea surface water and
deep seawater to generate electricity. OTEC requires pumping a large amount of deep seawater, which is clean, cold and
rich in nutrients. If the used OTEC seawater, i.e. a mixture of warm and cold seawater, is released to the sea surface, an
artificial upwelling is then created. The natural upwelling regions result in high levels of primary productivity and thus fishery
production. The upwelling area will also present low sea surface temperature. Hence, large enough artificial upwelling may
mitigate global warming. This process takes advantage of ocean thermal energy to generate clean energy, to create fishing
grounds and improve climate change. An interdisciplinary research program promoted by the UN will be necessary to achieve
this goal.
