Summary
The project will recover the first ever ice core record reaching beyond 1 million years (1 Myr) ago, extending our knowledge on climate and greenhouse gas forcing to 1.5 Myr, past the change in climate dynamics known as the Mid-Pleistocene Transition, where glacial/interglacial cycles changed from a 40,000 to a 100,000 yr cyclicity. This is a longstanding aim of international ice core science and is eagerly awaited by the entire palaeoclimate discipline and the wider climate community. Recovering a 1.5 Myr record of climate and greenhouse gases (GHGs) from Antarctica will resolve long-standing questions about the causes of change in the dynamics of climate over this timeframe, elucidating the linkages between the ocean, atmosphere, ice sheets and carbon cycle. This will provide a completely new, palaeo-based view of planetary boundaries and will tighten the constraints on the response of the Earth system over various timescales to future greenhouse gas emissions. The results obtained will be of paramount importance for the implementation of future Assessment Reports of the Intergovernmental Panel on Climate Change (IPCC) and to the Climate Action objective (#13) of the Sustainable Development Goals of the United Nations that aims to take urgent action to combat climate change and its impacts. [Such an oldest ice record is also a key priority for the international ice core community, as articulated by its planning body IPICS (International Partnerships in Ice Core Sciences).
Objectives
The overarching scientific goal driving BE-OIC is to obtain the first stratigraphically undisturbed, high-resolution ice-core record of climate and environmental changes over the last 1.5 Myr and use it to elucidate the role of slow parts of the climate system (carbon cycle, ice sheets) in climate change. By obtaining for the first time ever a continuous ice core extending up to the last 1.5 Myr, we will cover the Mid Pleistocene Transition (MPT, from approximately 1.2 Myr to 0.9 Myr before present).
