Question

The main reason(s) that subsequent work to CLIMAP supports thinner North American ice coverage than the CLIMAP maximum scenario is (are)

A.that the southern portion of the Laurentide Ice Sheet was underlain by soft, easily deformable sediment that would allow faster flow than the CLIMAP scientists had considered

B.the modeled thickness of ice that is required to produce the observed bedrock rebound history is thinner than the CLIMAP maximum scenario

C.new estimates for LGM temperatures around North America are much warmer than the CLIMAP reconstruction

Explanation / Answer

c. new estimates for LGM temperatures around north america are mch than the CLIMAP Reconstruction
