POB6. Meeting of the series "Special guest", 27.04.2022 (Wednesday), at 14:00.
You are kindly invited to the next meeting of the POB6 "Special Guest" series, which will be held on Wednesday, 27.04. at 14:00, online. This time the presentation of the paper will be given by Prof. Denis Didier Rousseau, employed at the Silesian University of Technology at the CN-D Institute of Physics.
The title of the presentation: "Understanding abrupt climate transitions of the last 3.2 Myr and their interest for the study of millennial climate variability, especially from European loess sequences".
The seminar will be conducted in English by Prof. Natalia Piotrowska from the Institute of Physics CN-D.
Persons who would like to participate in the seminar are requested to contact Prof. Natalia Piotrowska (Natalia.Piotrowska(a)polsl.pl) to get the link.
Below a short summary of the presentation.
Title: Understanding abrupt climate transitions of the last 3.2 Myr and their interest for the study of millennial climate variability, especially from European loess sequences.
The study of abrupt climate changes is a relatively new field of research that addresses paleoclimate variations that occur in intervals of tens to hundreds of years. Such timescales are much shorter than the tens to hundreds of thousands of years that the astronomical theory of climate addresses. I have revisited several high-resolution proxy records of the past 3.2 Myr. Doing so, I have demonstrated that such millennial variability, as observed in Greenland ice core records, appeared at about 0.9 Ma in Northern Hemisphere and are nevertheless affected by the orbitally induced insolation changes. A particular mechanism is proposed to explain how these abrupt climate changes are organized during a climate cycle, and how they are recorded in European loess sequences and what research perspective can be developed.
We welcome all interested participants!
