abstract = {The recent thinning and retreat of Antarctic ice shelves has been attributed to both atmosphere
and ocean warming. However, the lack of continuous, multi-year direct observations
as well as limitations of climate and ice shelf models prevent a precise assessment on how
the ocean forcing affects the fluctuations of a grounded and floating ice cap. Here we show
that a +0.3–1.5 °C increase in subsurface ocean temperature (50–400 m) in the northeastern
Antarctic Peninsula has driven to major collapse and recession of the regional ice
shelf during both the instrumental period and the last 9000 years. Our projections following
the representative concentration pathway 8.5 emission scenario from the Fifth Assessment
Report of the Intergovernmental Panel on Climate Change reveal a +0.3 °C subsurface ocean
temperature warming within the coming decades that will undoubtedly accelerate ice shelf
melting, including the southernmost sector of the eastern Antarctic Peninsula.},
