Current and projected permafrost temperatures for the Northern Hemisphere
(Romanovsky et al.

et al.

). We can expect increased redoximorphism and pervection in a warming
climate along the WAP and in coastal East Antarctica. Warming effect on soils
have been observed in the interior mountains of Antarctica, including reactiva-
tion of ice- and sand-wedge polygons, leaching of salts from soils, an increase in
the area of the hyporheic zone, and a loss in semi-permanent snow patches leav-
ing nivation hollows.
