Clarke S. 2021 Ice Shield Strategies
Description
This paper describes several ways by which the adaptation and deployment of a single, relatively simple technology can be made to mitigate then possibly reverse runaway global warming. The adaptation required is to use floating, buoy-mounted wind turbines to pump seawater onto sea ice, thereby creating deepening ice fields or lens/shield-shaped ice mountains around them. In seas shallower than a kilometre or so, these ice shields can be securely grounded on the seabed. They may also freeze together in rows, arrays, or onto land. Their annual accumulation of ice on top can be made to match, or exceed, that of any melting happening above and beneath. They can thus be made to cause selective glaciation in most polar and near polar regions that we choose, provided the winter there remains cold enough to generate sea ice.
