North Atlantic Session at the virtual EGU General Assembly 2021

OS 1.2 The North Atlantic: natural variability and global change

Convenors: Richard Greatbatch, Caroline Katsman, Monika Rhein and Bablu Sinha

The North Atlantic exhibits a high level of natural variability from interannual to centennial time scales, making it difficult to extract trends from observational time series. Climate models, however, predict major changes in this region, which in turn will influence sea level and climate, especially in western Europe and North America. In the last years, several projects have been focused on the Atlantic circulation changes, for instance OVIDE, RACE, OSNAP, and ACSIS. Another important issue is the interaction between the atmosphere and the ocean as well as the cryosphere with the ocean, and how this affects the climate.
Please note that the session will be held online, as described on the EGU 2021 website.

Invited Speakers: Damien Desbruyeres and Antje Weisheimer

We welcome contributions from observers and modelers on the following topics:

Climate relevant processes in the North Atlantic region in the atmosphere, ocean, and cryosphere
Response of the atmosphere to changes in the North Atlantic
Atmosphere – ocean coupling in the North Atlantic realm on time scales from years to centuries (observations, theory and coupled GCMs)
Interpretation of observed variability in the atmosphere and the ocean in the North Atlantic sector
Comparison of observed and simulated climate variability in the North Atlantic sector and Europe
Dynamics of the Atlantic meridional overturning circulation
Variability in the ocean and the atmosphere in the North Atlantic sector on a broad range of time scales
Changes in adjacent seas related to changes in the North Atlantic
Role of water mass transformation and circulation changes on anthropogenic carbon and other parameters
Linkage between the observational records and proxies from the recent past

Deadline for abstract submissions is 20 January 2021, 13:00 CET Further information here

Special Report of the Intergovernmental Panel on Climate Change shows risks of a slow reduction in greenhouse gas emissions

Global warming through greenhouse gas emissions has already reached 1°C above the preindustrial level. The new Special Report on the Ocean and Cryosphere in a Changing Climate of the Intergovernmental Panel on Climate Change reveals the resulting consequences for people and ecosystems:

The oceans are warmer, more acidic, and less productive.
Glaciers, ice sheets and permafrost are melting.
Rising sea levels are causing more severe extreme events at the coasts.

The report shows the benefits of fast and effective action to reduce greenhouse gas emissions, and conversely, escalating costs and risks of delayed action. More info here

RACE-PI Dagmar Kieke was honored for outstanding PhD supervision

The University of Bremen for the first time awarded a prize for outstanding PhD supervision. The prize acknowledges exceptional work and engagement in the support of early career scientists. In total, 80 PhD supervisors of all departments of the University of Bremen were nominated for the prize. We are very happy that RACE-PI Dagmar Kieke was honored with a second place for her special engagement! More info here.
