Boundary condition of grounding lines prior to collapse, Larsen-B Ice Shelf, Antarctica
Top-down rather than bottom-up change The Larsen-B Ice Shelf in Antarctica collapsed in 2002 because of a regional increase in surface temperature. This finding, reported by Rebesco et al. , will surprise many who supposed that the shelf's disintegration probably occurred because of thinning of...
