New webinar: WCRP My Climate Risk: Climate Voices on the Ground

The My Climate Risk (MCR) – Ateneo de Manila University (ADMU) Regional Hub, through the Ateneo Institute of Sustainability, invites you to the first of two online webinar series, “Climate Voices on the Ground: Perspectives from Different Sectors”, which seeks to foster discussion on the contexts and experiences of climate change among different communities and stakeholders.

In this series, the perspectives of community-based organizations, coastal and small island communities, and microenterprises will be highlighted. The discussions will revolve around how they make sense of their experience of climate change and what their climate information needs are.

The webinars will occur on three successive Fridays of October 2022: on the 14th, 21st, and 28th, each from 4:00-5:30 PM (Philippine Time) or 8:00-9:30 AM UTC. We invite all interested parties to register at

Now open: Call for nominations to the SPARC Scientific Steering Group

We are currently inviting nominations from highly enthusiastic and dedicated experts to  become a member of the SPARC Scientific Steering Group (SSG) – you can either nominate a candidate or nominate yourself. The SSG and co-chairs guide SPARC’s priorities and research activities and work together with, and are supported by, the SPARC project office. The SSG provides leadership for SPARC and represents a broad spectrum of disciplines and nationalities, including both junior and senior scientists. The duties and responsibilities of SSG members are outlined in the Terms of Reference. SSG members are expected to provide scientific guidance and oversight to the SPARC community and its activities and participate in developing and reviewing the scientific strategy for the SPARC community.

More information and the online form for your (self-)nomination can be found here.

The four-year membership term will be from January 2024 – December 2027, with a possible two year extension. Among all applications received, the current SSG and co-chairs will propose new members for final approval by the Joint Scientific Committee (JSC). 

Note: all applications/nominations received since 2019 are still being considered.

The deadline for submitting your nomination is 1 November 2022. (Self-)Nominations can be submitted through an online form on the SPARC website or via email to the SPARC project office.

Announcement: Webinar series: Explaining and Predicting Earth System Change

The WCRP Explaining and Predicting Earth System Change Lighthouse Activity invites you to join the first webinar of the series that will provide a discussion forum on topics focused on predicting and explaining a range of different climate phenomena and events, while supporting the further development of a scientific agenda.

This first webinar will focus on record breaking extreme events and will provide a view of such events in different regions of the world.


  • Erich Fischer (ETH Zurich, Switzerland)
  • Understanding and quantifying very rare and record-shattering extremes

  • Maria Laura Bettolli (University of Buenos Aires, Argentina)
  • Record extreme precipitation events in Southeastern South America: from observation to modelling

  • Tianjun Zhou (Institute of Atmospheric Physics, China)
  • Record-breaking extreme events over Asia: Attribution and Projection

The event will take place on 21st September 2022, from 12:00hs to 13:30hs UTC. Speakers will give a 20-minute talk each followed by a round table discussion, with questions from participants.

Deadline extension and remote participation: WCRP Workshop on Modelling the Climate System at ultra-high resolution

The WCRP Digital Earths Lighthouse Activity and Earth System Modelling and Observations (ESMO) Core Project are jointly convening a workshop to bring together all relevant communities interested in ultra-high-resolution modelling. 

There is an opportunity for remote participation on October 5th 2022.  You can register for an online breakout session here: 

The workshop will be in person from October 3-7, 2022 at the National Center for Atmospheric Research (NCAR) in Boulder, CO, U.S.A.  The talks will be recorded and we are making available a pair of virtual breakout sessions to serve participation in different time zones, to be conducted on Wednesday, October 5th 2022 for 1.5 hours each. 

This workshop is motivated by the urgent need for improved climate information and the major advantages and scientific potential of ultra-high-resolution climate modeling.

The intended outcomes include the establishment of a global research network with expertise in ultra-high-resolution (kilometer-scale or finer) global and regional Earth system modelling including its individual components. The workshop outcomes will be documented in a white paper.

For those who still want to submit an abstract and register for in person participation, please go to the workshop website for more information:

●      Abstract submission deadline: September 14, 2022

●      Registration deadline: September 20, 2022
