LGM sensitivity experiments, existing, in progress and planned
LGMGHG = Pre-industrial conditions with LGM greenhouse gases imposed
LGMICE = Pre-industrial conditions with LGM ice sheet imposed
Flat = LGM with “flat ice sheet” - ice sheet extent but no change in altitude
Brown = LGM with “brown ice sheet” - ice sheet height but no change in ice sheet extent
(*) - Green Laturentide topography, ( no sea level, GHG, orbit); White Laurentide topography (no sea level, GHG, orbit); White Northern Hemisphere Ice extent (no topography, sea level, GHG, orbit)
