Tuesday May 21th, Gianluca Marino, Distinguished Researcher of the Marine and Environmental Geology Research Group (CIM-UVigo) and Honorary Senior Lecturer of The Australian National University, will present at the “Café con Sal” conference the lecture “The nature of (palaeo)climate change“, in which he will discuss the main features of the “ice-age cycles”, their pattern of variability, their causes, and how to exploit these episodes of climate change in climate sensitivity assessments.
Over the last million years the Earth’s climate repeatedly fluctuated between ice and warm ages with a ~100,000 year periodicity. These cycles arose from changes in the Earth’s orbit and superimposed climate feedbacks (e.g., CO2), and featured gradual global cooling and ice-volume build-up, followed by rapid warming and melting.
Gianluca Marino uses geochemical, micropaleontological, and sedimentological tools as well as probabilistic statistics to quantitatively determine the timing, magnitude, and rates of (past) ocean and climate change. Since his incorporation at the University of Vigo, where he was awarded a fellowship within the framework of the “Program to attract Excellent Research Talent”, he is working on various projects targeting the palaeoclimate record to decipher how Earth’s climate operates and changes.
During the conference, Gianluca will present the main features of the “ice-age cycles”, highlighting the progress that was made to characterise their pattern of variability and understand their causes. Next, he will focus on some work developed by his group that contributed to address two key aspects of the ice-age narrative: the sequence of events that terminates an ice age; and the processes that control the CO2 variations associated with these cycles. Finally, he will show some theoretical considerations to exploit the palaeoclimate record to constrain climate sensitivity, which is a central climate metric to evaluate the amount of warming expected for the next century and beyond.
The conference will take place at the conference room of the ECIMAT at 11:00h (CEST) and will be live streamed on http://tv.uvigo.es/es/directo/1.html and permanently available on CIM and UVigoTV websites.
