Some scientists have suggested that global warming could melt frozen ground in the Arctic, releasing vast amounts of the potent greenhouse gas methane into the atmosphere, greatly amplifying global warming. It has been proposed that such disastrous climate effects could be offset by technological approaches, broadly called geoengineering. One geoengineering proposal is to artificially whiten the surface of the Arctic Ocean in order to increase the reflection of the Sun's energy into space and restore sea ice in the area.
