Finnegan 2009), whichwould allow increased infrared cooling (an option
that could be applied year-round). None of these tropospheric or surface-
based systems would be likely to contribute to depletion of stratospheric
ozone, and none of these approaches would increase the ratio of diffuse to
total solar radiation over low- and mid-latitude regions that might come to
rely on direct solar energy-production technologies.
12.5.2 Potential for Limiting Ice Sheet Deterioration
While mountain glaciers and ice caps hold about 1 m of sea level, the
Greenhouse ice sheet contains about 7 m and the Antarctic ice ...
