Ice core evidence for significant 100-year regional warming
on the Antarctic Peninsula.
Geophysical Research Letters, Vol. 36, L20704,
doi:10.1029/2009GL040104
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°C 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.
STUDY NOTES: Annual average oxygen isotope (d18O) data from the Gomez ice core,
southwestern Antarctic Peninsula, drilled in 2007. Isotope data
measured on a VG SIRA series II analyser with analytical precision
of 0.07 per mil.
