Interactions entre pergélisol et environnement lacustre. Les changements environnementaux datant de l’Holocène dans les zones maritimes antarctiques

Antarctica: understanding the past, to predict the future

My research will give answers to some uncertainties regarding the dynamics of the natural system in the Maritime Antarctic. We need to frame the recent warming within the natural climate variability of the last millennia in this particularly climate-sensitive region. As part of the duty that the Antarctic scientific community owes to society, researchers should provide new knowledge about its present and past natural climate evolution in order to forecast extreme climate events such as droughts and floods as well as to provide insights about the short-, mid- and long-term Earth climate evolution, in general, and about the recent warming that is affecting the global climate over the last decades. The scientific community needs to generate more data to better understand the negative (catastrophic?) effects that the present-day warming trend may trigger in the Antarctic, and thus in the whole climate system, in order to anticipate and mitigate its consequences as much as possible.
