"Sea level rise is now unstoppable"
John is that really the case.
The past 15 years atmospheric warming has decreased, it is believed, due to increased accumulation of heat in the deeper ocean as a result stronger than normal trade winds that have piled up surface heat in the Western Pacific; forcing it deeper.
We can replicate this natural phenomenon with an ocean thermal energy conversion (OTEC) system that moves heat as deep as 1000 meters beneath the surface with what is commonly referred to as a heat pipe. These are the same devices that move heat away from the vital components of modern electrical devices and deposit that heat safely in the atmosphere.
The oceans are on average 4,267 meters deep. They are massive and absorb tremendous amounts of heat with limited temperature increases. To a depth of 2,000 meters they have warmed less than a tenth of one degree Celsius in the past 50 years in spite of the fact that they are accumulating heat a rate of about 2 Hiroshima bombs worth every second.
This heat however is not with out consequences. It causes the oceans to expand, leading to sea level rise, it drives hurricanes and undermines the polar icecaps whose melting will be the driver of the large sea level increases that are expected by the end of the century.
By moving surface ocean heat through a heat engine, OTEC can produce as much energy as is currently derived from fossil fuels. Moving it away from the surface robs the power of hurricanes and when it is relocated to a depth of 1,000 meters it produces half the sea level rise as it does on the surface because the coefficient of expansion of sea water is half as great at that depth and ocean temperature as on the tropical surface.
Dr. Paul Curto, former Chief Technologist with NASA, has pointed out that when OTEC was first discussed in relation to global warming at a 1977 conference in Miami one of the concerns was that it might cause an Ice Age.
Although a kilometer of ice over New York to save Miami is not a saleable proposition, enough cooling to prevent further losses of Artic, Antarctic and Greenland ice mass would be beneficial to all.
