|a Mountain glaciers worldwide have undergone net recession
over the past century in response to atmospheric warming1,
but the extent to which this warming reflects natural versus
anthropogenic climate change remains uncertain. Between
about 11,500 years ago and the nineteenth century, progressive
atmospheric cooling over the European Alps induced glacier
expansion, culminating with several large-scale advances
during the seventeen to nineteenth centuries. However, it
is unclear whether this glacier behaviour reflects global or a
more regional forcing. Here we reconstruct glacier fluctuations
in the Southern Alps of New Zealand for the past 11,000
years using 10Be exposure ages. We use those fluctuations to
estimate the associated temperature variations. On orbital to
submillennial timescales, changes in glacier snowlines in New
Zealand were linked to regional climate and oceanographic
variability and were asynchronous with snowline variations
in European glaciers. We attribute this asynchrony to the
migration of the intertropical convergence zone. In light of
this persistent asynchrony, we suggest that the net glacier
recession and atmospheric warming in both regions over the
past century is anomalous in the context of earlier Holocene
variability and corresponds with anthropogenic emissions
of greenhouse gases. |
