Existence of an ice cap during the mid-Cretaceous period (120–90 Ma): an AGCM investigation
International audience Many questions remain concerning whether or not an ice cap existed during the mid-Cretaceous period (120–90 Ma). Other than data and observations from ice-rafted materials, atmospheric general circulation models (AGCMs) may be appropriate tools to investigate whether changes i...
