Clarke S. 2021 Ice Shield Strategies

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.
