Short summary
Short summary
The opening of the South Atlantic Ocean, starting ~ 140 million years ago, had the potential to influence the global carbon cycle and climate trends. We use 36 climate model experiments to simulate the evolution of ocean circulation in this narrow basin. We test different combinations of palaeogeographic and atmospheric CO2 reconstructions with geochemical data to not only quantify the influence of individual processes on ocean circulation but also to find nonlinear interactions between them.

Short summary
One of the challenges is to elucidate if climate during the Jurassic was warmer than present day, with no ice caps. The Pliensbachian Cooling event (Lower Jurassic) has been pointed out as one of the main candidates to have developed ice caps. The Rodiles section of the Asturian Basin (Northern Spain), allows the characterization of several climatic changes of probable global extent.
