Due to the lack of long continuous climate proxy records, the role of Antarctica in the Plio-Pleistocene climate cooling over the last 5 Ma is still unclear and has been poorly investigated. This project proposes to combine data and numerical modeling approaches of different complexity to improve our knowledge of Southern Hemisphere high and low latitudes climate teleconnections and their influence on Northern Hemisphere climate processes. Investigating the interplay between Southern Hemisphere high- and low-latitudes climate is indeed of high importance to understand the future evolution of our present climate, especially in case of partial melting of Antarctica.
24 months da 27/06/2014 a 26/06/2016
General aims
- Identify the main global climate transitions in the ANDRILL-MIS and IODP U1361 records over the last 3.5 Ma.
- Model and identify Plio-Pleistocene climate teleconnections, i.e. links between atmosphere and ocean and identify the mechanisms responsible for dynamical changes in Southern Hemisphere climate over the 3.5 Ma – 2.5 Ma time period.
- Define the importance of the Southern Hemisphere teleconnections in various climatic contexts identified over the 3.5 Ma – 2.5 Ma time period.
- Determine the influence of the southern teleconnections across the Plio-Pleistocene boundary on the climate of Southern Hemisphere low latitudes.
