climate and ice-shelf history. Nature 489: 10.1038/nature11391.
The authors write that "the Antarctic Peninsula is at present
one of the most rapidly warming regions on Earth (Vaughan et
al., 2003)," noting that "historical observations since 1958 at
Esperanza Station document warming equivalent to 3.5 ± 0.8°C per
century." What was done In an attempt to determine just how
unprecedented this warming might have been compared to the rest
of the Holocene, Mulvaney et al. drilled an ice core to the bed
of the ice cap on James Ross Island, which lies just off the
northeastern tip of the Antarctic Peninsula, next to an area
that has experienced a series of recent ice-shelf collapses. And
based on deuterium/hydrogen isotope ratios of the ice (δD), they
developed a temperature history of the region that spans the
entire Holocene and ex
