Abstract:
Because ice shelves respond to climatic forcing over a range of time
scales, from years to millennia, an understanding of their long-term
history is critically needed for predicting their future evolution. We
present the first detailed reconstruction of the Larsen C Ice Shelf (LCIS),
eastern Antarctic Peninsula (AP), based on data from sediment cores
recovered from below and in front of the ice shelf. Sedimentologic and
chronologic information reveals that the grounding line (GL) of an expanded
AP ice sheet had started its retreat from the midshelf prior to 17.7 ± 0.53

Sometimes archaeological evidence may be quite clear, but the story it tells can be mystifying. One such conundrum has been archaeological evidence of relatively intense hilltop farming thousands of years ago in the relatively arid Jerusalem area, the Judean lowlands and northern West Bank. The Iron Age and Byzantine farmers cultivated the chalky, hilly land mostly by terracing. Meanwhile in the abundantly rainy Galilee in Israel’s north, there is no evidence of terracing. The area was just as densely populated but the people seem to have eschewed exploiting the hills, only cultivating crops at low level. It seemed counterintuitive to find the evidence of heavier farming in the drier lands of Jerusalem and Samaria than in the lovely Galilee.
