SPARC (Stratosphere-troposphere Processes And their Role in Climate) is holding its 7^th General Assembly (GA) from 24^th to 28^th October 2022. The format of the SPARC GA will be different from past GAs, as it will be on a multi-hub basis with three locations (hubs) confirmed at the National Center for Atmospheric Research (NCAR), in Boulder, USA, the European Centre for Medium-Range Weather Forecasts (ECMWF), in Reading, UK, and the First Institute of Oceanography (FIO) in Qingdao, China.

•  Deadline for abstract submission extended to 5 pm UTC on 6 June 2022
• For more information and submissions, visit the conference webpage.

A reminder that the WCRP Academy currently has an open call for nominations to its Steering Group. The WCRP Academy Steering Group is responsible for the implementation of the Academy's science plan, its overall direction and services, as well as resource allocation. Full details are provided on the Academy webpages. The deadline is 31 May 2022.

A reminder that the deadline for nominations for membership of the WCRP Joint Scientific Committee (JSC) will close on 31 May 2022. We invite all interested candidates to read more about the important role that JSC members play and access the nomination form on the open call webpage.

We are fast approaching the abstract submission deadline for the  6th WGNE Workshop on Systematic Errors in Weather and Climate Models hosted by the European Centre for Medium Range Weather Forecasts (ECMWF), in Reading (UK) on 31 October - 4 November 2022. The workshop will bring together a wide range of experts on simulating the Earth System including atmosphere, ocean, waves, land-surface, atmospheric composition, cryosphere, and associated disciplines to advance the understanding of systematic simulation errors at all timescales.

Early career researchers from selected countries will be able to enter a competition for best abstracts for oral presentations. The World Meteorological Organization (WMO) is pleased to offer funding for travel to ECMWF (UK) to the winners of the competition. Please see https://events.ecmwf.int/event/241/page/122-abstract-competition for details.

• Abstracts are due 31 May 2022

We warmly invite you to attend the next webinar in the 'Tipping elements, irreversibility, and abrupt changes in the Earth system' Discussion Series. On 12 May 2022 at 10:30 CEST, we will explore tipping towards positive social change with two talks:

• Social tipping dynamics – Ilona Otto (University of Graz)
• What are the sensitive intervention points needed to make the green energy transition happen as quickly as possible? – Doyne Farmer (University of Oxford)

To register, please see the Discussion Series website.

The second Model Hierarchies workshop will be held 29 August - 1 September 2022, as a 3.5-day in-person (covid permitting) workshop at Stanford, CA (USA). As last time, we solicit talks on the design and use of modeling hierarchies in all aspects of Earth system science, covering the major climate system components -- atmosphere, ocean, land, cryosphere, biosphere -- but this time also underline our interest in exploring the ways in which such models are connected to the downstream uses of this data in the study of climate impacts. The workshop will be structured around talks in a single-session format, interspersed with poster sessions during the recesses. There will be plenty of time in between sessions for collaborative and social discussion.

• Deadline for abstract submission and application for financial support is extended to 15 May 2022, don't miss the date!
