Study shows above ice warming responsible for Larsen-B Ice Shelf collapse, not instability

(Phys.org) —An international team of researchers has concluded that the Larsen-B Ice Shelf collapsed in 2002 because of warmer surface air temperatures, not instability from below, as some have suggested. In their paper published in the journal Science, the team describes how they collected and examined sea floor samples in the area where Larsen-B collapsed and found no evidence of structural damage that could have caused the shelf to collapse—that leaves warmer temperatures from above as the only logical cause.
