CMIP evolution

Priority Variables Consultation
The CMIP International Project Office (CMIP IPO) invites you to take part in this consultation on priority variables for inclusion within a core set of variables forming the baseline for exchange of climate model data, in any intercomparison project, in accordance with FAIR data and Open Science principles. This consultation is relevant to those involved in developing and operating climate models, data infrastructure and those utilising climate model outputs.  To know more and to fill in the online form click here. Consultation closes 18:00 UTC Friday 23 September.

Open call for CMIP7 Task Teams
This open call is an invitation to enthusiastic and motivated individuals from across the community, and beyond, to join the CMIP7 Task Teams and contribute to the future direction of CMIP. The first set of Task Team call texts and the application form are available here with an application deadline of 2nd October 2022.


Calls for Poster Clusters and Side Events at the WCRP OSC 2023

Poster Clusters

Poster clusters should be designed to bring together a community working on a specific topic within the broader conference themes. The aim is to help participants to organize their poster viewing and to provide a forum for discussion about the cluster topic. In addition to dedicated on-site poster sessions, all posters will be available on the hybrid platform poster gallery at least two weeks before the conference. Virtual poster sessions will be organized during these two weeks. The poster cluster names will be listed under the OSC programme sessions in the abstract submission system when it opens in December 2022.

If you or your organization/working group/etc., would like to propose a poster cluster topic, please click here to know more about the poster cluster application and to fill in the survey form, no later than 30 September 2022.

Side Events

The OSC will occupy the entire Kigali Convention Center during the week of 23-27 October 2023. The venue has many rooms of varying sizes that can accommodate workshops, meetings, learning labs, townhalls or other events.There is also the option to propose a video for transmission on hybrid platform during breaks and possibly during the conference itself. If you or your organization would like to host an event at the OSC, please click here to know more about the side event application and to fill in the survey form.

APPEAR aims to bring together research exploiting perturbed parameter ensembles (PPEs) to understand and predict the behaviour of the atmosphere and climate system.

Registrations are open for the Analysis of PPEs in Atmospheric Research (APPEAR) virtual workshop to be held over 2 days: 18 October (15:00-19:00 UTC) and 19 October 2022 (08:00-11:00 UTC). The workshop is organised under the new WCRP Earth System Modelling and Observations (ESMO) Core Project and will showcase the wide range of PPE-related research across atmospheric science. The overall aims are to define the range of approaches and applications, to share expertise on how the many challenges of PPE creation and analysis are being tackled, to build a community of researchers, and to scope out the opportunities for further development and collaboration.

 WCRP invites the community to to nominate candidates (including self-nomination) to become members of the Regional Information for Society (RIfS) Scientific Steering Group (SSG). The WCRP Regional Information for Society (RIfS) Core Project focuses on research that underpins provision of actionable information for society’s response to climate variability and change. RIfS is in its establishment phase and presents opportunities for framing and developing the directions and priority foci of research on climate for society.

  • For more details on the nomination process, read more here.
  • Deadline for nominations: 30th September 2022

Tipping Points - from climate crisis to positive transformation

This meeting, co-convened by Johan Rockström, Director of the Potsdam Institute for Climate Impact Research, and Tim Lenton, Director of Global Systems Institute, is a ‘call to action’ to form an alliance to improve warnings of the proximity of catastrophic climate tipping points and to accelerate positive tipping points to avert the climate crisis. Speakers will be from academia, industry, government, and third sectors. The meeting is sponsored by the WCRP Safe Landing Climates Lighthouse Activity.

Early registration for the "Tipping Points - from climate crisis to positive transformation" meeting will close on 8 August 2022. Reserve your place now!
