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 linktr.ee/MCR_ADMU.

This year marks the 30th anniversary of SPARC, a core project of the World Climate Research Programme (WCRP). In this time, SPARC has evolved into a major international research coordination hub for atmospheric sciences, with the primary goal to facilitate research that improves our understanding of atmospheric processes and their role in climate.

SPARC is particularly recognised for its lively scientific community. To celebrate SPARC’s achievements over the last three decades, we invite you all to celebrate with us and join us for a series of three webinars leading up to the grand SPARC General Assembly in October 2022.

We are delighted to announce we will host the third and last SPARC 30th anniversary webinar on Friday 7 October 2022 at 12.00 UTC. Prof. Thomas Peter from the ETH Zürich will give a presentation on “Research on climate intervention by stratospheric aerosol injection (SAI) – should SPARC engage?”

To participate the webinar register here.

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.

SPEAKERS:

• 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 21^st 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.

Registrations are open: https://explaining-and-predicting-extremes.eventbrite.co.uk

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: https://forms.gle/L58Jt5toSU8eVzM29 

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:

The organising committee

Date: October 11-13, 2022.

Venue: Kulturhuset in Oslo, Norway, and online.

Register here! OBS! Updated link!!

Free of charge! First come – first serve: max 50 onsite participants.

The deadline for registration is 30 September at 23:59 UTC.

The main objectives of this workshop are to:

• promote reconciliation of global and regional climate models (GCMs, RCMs), empirical statistical downscaling (ESD) and historical observations/reanalyses for better information in support of robust future climate outlooks and climate change adaptation
• discuss how to further facilitate the use of climate information that is embedded in the data that it produces
• discuss what information is needed for various purposes and how to use it.  

How do we best use the available information based on the context? We will discuss principles for consolidating downscaled information in decision-making/climate services/climate change adaptation. We also want to bring in know-how on how to involve statistics. The workshop, hosted by the Norwegian Meteorological Insitute, is held in collaboration with the Norwegian Public Health Institute and the Norwegian Centre for Climate Services, to foster co-production of knowledge on climate-health issues and for the provision of robust actionable information.
