Computational science is crucial for delivering reliable weather and climate predictions. In this article published in  Nature Computational Science, the authors discuss the present limitations in the field and propose the design of a novel infrastructure that is scalable and more adaptable to future, yet unknown computing architectures.

It is with deep regret that we have learnt of the passing away of Professor Paul Josef Crutzen.

Paul Crutzen, a prominent atmospheric chemist, former Director at the Max Planck Institute for Chemistry in Mainz, Germany, and of the Atmospheric Chemistry Division at the National Center for Atmospheric Research in Boulder, USA, passed away on 28 January 2021.

Recent assessments from the Intergovernmental Panel on Climate Change (IPCC) imply that global mean sea level is unlikely to rise more than about 1.1 m within this century but will increase further beyond 2100. Even within the most intensive future anthropogenic greenhouse gas emission scenarios, higher levels are assessed to be unlikely. However, some studies conclude that considerably greater sea level rise could be realized, and a number of experts assign a substantially higher likelihood of such a future.

The European Union (EU) intends to become climate neutral by 2050, and the set of policies designed to bring about this green transition — the European Green Deal — was announced in December 2019.
For its green transition, the EU plans to fund the development of digital twins of Earth. For these twins to be more than big data atlases, they must create a qualitatively new Earth system simulation and observation capability using a methodological framework responsible for exceptional advances in numerical weather prediction.

This effort is very relevant to WCRP's effort to bring the digital twin concept to the climate science community.
