|a We present a new 150-year, high-resolution, stable
isotope record (d18O) from the Gomez ice core, drilled on the
data sparse south western Antarctic Peninsula, revealing a
2.7 degree celsius rise in surface temperatures since the 1950s. The
record is highly correlated with satellite-derived temperature
reconstructions and instrumental records from Faraday
station on the north west coast, thus making it a robust
proxy for local and regional temperatures since the 1850s.
We conclude that the exceptional 50-year warming,
previously only observed in the northern Peninsula, is not
just a local phenomena but part of a statistically significant
100-year regional warming trend that began around 1900. A
suite of coupled climate models are employed to demonstrate
that the 50 and 100 year temperature trends are outside of
the expected range of variability from pre-industrial control
runs, indicating that the warming is likely the result of
external climate forcing. |
