| v Abstract This thesis focused on the Atlantic Meridional Overturning Circulation (AMOC) stability and global climate responses of an altered AMOC in the late Neogene by performing computer simulations, using both intermediate complexity climate models and state-of-the-art coupled climate models. Two time slices were studied: 1) 38 ka BP (kilo years before present), during Heinrich event 4, and 2) around 4- 5 million years ago, when the Panamanian Seaway finally gradually closed. The AMOC is one of the most important climate systems modulating the world climate due to the significant amount of oceanic transport of heat, carbon and nutrients. Understanding the AMOC stability behaviour is essential to investigate climate in the past and present as well as... |
