In July 2020, the European External Action Service of the European Commission launched a public consultation on the way forward for the European Union’s Arctic policy. The consultation was held to re-examine the role of the EU in Arctic affairs, to revise the priorities of the current Joint Communication on an integrated European Union policy for the Arctic and the actions thereunder, and to identify possible new policy areas to be developed.

This article gives an overview of the recent advances on the interactive modelling of ice sheet dynamics in Earth System Models, and the implications for reducing the uncertainty of sea-level rise projections, especially when considering multi-centennial timescales of changes or low-likelihood high-impact scenarios.

In this article, we provide an overview of current understanding of the land-to-ocean carbon fluxes. We describe the new conceptual model of the land-to-ocean aquatic continuum (proposed by Regnier et al, 2022, Nature), as well as ongoing work to include this new knowledge in Earth System Models.

The latest ZERO IN report from the CONSTRAIN project dives into the science set out in the recent Intergovernmental Panel on Climate Change assessments. It investigates what our climate future could look like by 2050, depending on whether we take action in line with the Paris Agreement, or decide to follow current national policies and plans which still largely lack the action and ambition needed to stop global warming.

New study on the impacts of wildfire emissions on fine particle air pollution in the western US until the end of the 21st century, under different climate change scenarios.
This work highlights the fact that when committing to a particular level of future warming, we are also committing to a particular level of fine particle air pollution. This has to be taken into account when considering mitigation and adaptation strategies.
