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.

In the past 15 years the media impact of the annual Global Carbon Budget has increased significantly. However, as the narrative on the global emissions trajectory starts to change, and the demand for scrutiny of emissions reduction efforts increases, the role of the Global Carbon Budget may need to shift.

To drive the evolution of the activity in an ongoing strategic review the Global Carbon Project would like you to provide them with feedback in filling out the survey at https://forms.gle/3uhdDa97LA3HMMHd8. This survey is intended to inform a strategic review process for the Global Carbon Budget and to explore new directions for greater impact.

The World Climate Research Program (WCRP) is moving towards a new programme structure in an era where we urgently require solutions to the challenges of climate change. To find out more click the heading above.

Above: The new WCRP structure.

WCRP Joint Scientific Committee member, Pierre Friedlingstein, and colleagues have published the Global Carbon Budget 2020 (https://doi.org/10.5194/essd-12-3269-202).

Produced by more than 80 researchers working from universities and research institutions in 15 countries, this annual product compiles and assesses reports, papers, measurements, and model outputs to quantify sources and sinks of carbon in units of gigatonnes of carbon per year (GtC yr-1).
