IP061: The SCAR Antarctic Climate Evolution (ACE) Programme
The present Antarctic ice sheet has existed for approximately 34 million years. Understanding the response of the Antarctic ice sheet to climatic forcing is essential because changes in the ice sheet can have major impacts on global sea level and can impact the entire climate system through a wide range of physical and chemical feedbacks.
The SCAR Antarctic Climate Evolution (ACE) Programme represents the interests of a large land and marine geoscience research community focusing in deciphering the record of the onset and the response of the Antarctic ice sheets to past climate changes across a range of timescales. ACE coordinates the integration between geophysical and geological records of past ice sheet behavior and coupled climate, ocean, and ice sheet models. This paper gives an overview of the ACE Programme, including its data-model philosophy, structure, achievements, publications and outreach.
