Since the Antarctic Treaty entered into force in 1961, representatives of the participating nations have met regularly for the Antarctic Treaty Consultative Meeting (ATCM).

The 44^th ATCM, from 23 May till 2 June 2022, is being hosted by Germany in Berlin. Matters on the agenda include topical questions relating to Antarctica and further developments on the coldest continent on our planet.

• Session 84: Extending the limits of ice core science beyond new analytical, conceptual and inter- disciplinary frontiers 

Understanding the past climate variability and sensitivity from glacial archives is fundamental for placing the current changes in a longer-term context. The scientific ice core community is currently putting an enormous effort towards retrieving the oldest continuous ice core from Antarctica (Project Beyond EPICA) and training a new generation of ice core scientists capable of analyzing, interpreting, and modelling the new records that will be obtained (ITN DEEPICE project).

• Session INQUA-MARE: Pole to pole teleconnections as registered in Antarctic and Arctic Holocene Archives

With the expression “pole to pole teleconnections” we refer to climate anomalies in the Arctic region, caused by oceanic or atmospheric processes originating in the Antarctic region and vice versa. These anomalies are well recognized in today’s climate but are detected with difficulties in the paleoclimate archives. Within the frame of the CMP-Coastal & Marine Processes (Coastal and Marine Processes) Commission and of the SPLOSH (Submerged Palaeolandscapes of the Southern Hemisphere) International Focus Group, the “INQUA MARE” scientific action (INtegrated QUAternary MArine REcord at Sensitive Latitudes, 2020-2024) aims to exhaustively explore the interactions between the tropical and polar regions by studying the Holocene marine sediment records from Arctic, Antarctic and Tropical regions, considered as the most sensitive areas to climate change. With this session, we would like to “recap” the first two INQUA-MARE workshops focused on the Antarctic and on the Arctic realms respectively, to open the discussion also to the terrestrial environment, and to promote next INQUA-MARE workshop that will focus on tropical areas and worldwide teleconnections between high and low latitude regions. We therefore welcome contributions that explore (and possibly compare) Holocene marine and terrestrial records from the Antarctic and Arctic regions highlighting anomalies ascribable to the climate fluctuations regime on the opposite Pole.
