Impressions from the WCRP JSC-41 Conference in May 2020

The WCRP Joint Scientific Committee Session is an annual meeting where the leaders of the WCRP research community discuss progress towards the Programme’s objectives and make decisions that will determine the future direction of the Programme. The 41st Session of the WCRP Joint Scientific Committee (JSC-41) was conducted as an online meeting 18-22 May 2020.

The 94 participants in this first ever online JSC meeting were during three days discussing the future elements and structure of World Climate Research Programme, WCRP. The Cooordinated Regional Climate Downscaling Experiment CORDEX was represented by the co-chairs as well as the director and the administrator from the International Project Office of CORDEX at SMHI in Sweden.

Professor Detlef Stammer and Dr Helen Cleugh was asked about their impressions from the conference. Professor Detlef Stammer from University of Hamburg, Germany is the JSC Chair.  Dr. Helen Cleugh is from CSIRO, Australia and is the JSC Vice Chair.

The general purpose of this JSC meeting was to review progress of WCRP activities, address questions and concerns that come up in the core WCRP activities, and specifically to think strategically about changes in directions or new activities required to address new problems.
“Certainly it was the expectation that we would be able to deal with these responsibilities and in an efficient manner given that the meeting had to be entirely virtual in character,” says Detlef Stammer.

Implementing a new strategic plan

One of the central questions of this JSC meeting was how to implement the new WCRP Strategic Plan, building on progress made in this direction during the last year, and to consider what structures of WCRP might be best suited for this.

“Personally I saw a substantial progress in all these aspects. In particular we have seen a large enthusiasm for a change and much agreement on possible directions. It is now on us, the WCRP family, to do our homework assignments and come back later this year for an extraordinary JSC meeting where we intend to decide how to move forward and what the basic structure will be. For me especially this latter aspect was an extremely positive and major outcome,” says Detlef Stammer.

“We were both surprised, and pleased, that we were able to have meaningful discussions and make progress. It’s a good demonstration that, with sufficient pre-work and commitment from all participants; this style of meeting can work,” says Helen Cleugh.

Scientific insight into the climate system

As already documented in the WCRP Strategic Plan 2019 – 2028, a main focus for the WCRP in the future will remain on gaining basic scientific insight into the functioning of the climate system. However, providing the knowledge to create regional to local climate change information and bridging climate science and society will gain substantially in emphasis and effort.

“All this will entail that we will come closer together with our partners to solve urgent climate problems and to do this in a timely manner – based on relevant and credible science. Society requires answers and input; WCRP with its partners stand ready to live up to those expectations,” says Detlef Stammer.

Now there is homework to do including lots of consultations, brainstorming among and across the core activities of the WCRP and with the partners. It will also include regional consultations with part of the communities that were not involved in the recent discussion so as to bring everybody into the loop and get input, especially from communities representing the global South. The goal is to come up with a final design of the structure for the new WCRP.

“In addition to designing a structure that is ‘fit-for-purpose’ for the new WCRP, we are also scoping out some exciting new “lighthouse activities”. These are major projects, experiments or infrastructure building blocks that require the WCRP to draw upon the expertise that sits across the whole WCRP, and within our partner agencies and programs, to deliver new insights and scientific advances that will benefit society,” says Helen Cleugh.

CORDEX regional information gains in importance

Providing regional information, where CORDEX is a major contributor, for society will gain in importance and emphasis.
“By supporting the science that underpins the delivery of regional information, building a more coherent and integrated approach, and providing greater visibility for these activities, we also hope to build more effective and stronger relationships with partners and stakeholders – who are critically important in achieving the goals of bridging climate science and society,” says Helen Cleugh.

“The regional activities could benefit by bringing them all together to be equal in visibility and emphasis to other traditional WCRP efforts and scientific domains. This will entail many related efforts thereby giving them a boost in the entire WCRP work and entraining also more other disciplines required to deal with them, such as represented under the ISC,” says Detlef Stammer.

William J. Gutowski Jr is a lead author for IPCC AR6

William J. Gutowski Jr, former Co-Chair of CORDEX Science Advisory Team (SAT), is a Professor of Meteorology working at Iowa State University, Ames, Iowa, USA. He is currently a Lead Author for the IPCC Sixth Assessment Report, Chapter 10 (Linking global to regional climate change).

Professor Gutowski wearing a red jacket is standing on a field with water behind him.

He thinks that regional climate information is very important.
“The AR6 is the first IPCC assessment report in which Working Group 1 has a substantial portion of its report devoted to climate information for regions.  Primary chapters in this regard are 10, 11, 12 and the Atlas, all of which have a heavy emphasis on regional climate.  Other chapters, especially 6, 8 and 9 also give sizeable emphasis to regional climate.  Regional climate simulations, especially under CORDEX, are providing substantial climate information to the assessment. The common domains and common time periods for CORDEX simulations has meant that there are multi-model simulation archives available for many regions around the world.  The CORDEX framework has been the foundation for these multi-model efforts, creating the opportunity for their wide use in the AR6 WG1 report’”

Previously he was also a Contributing Author to the IPCC Third and Fourth Assessment Reports (chapters on regional climate) and he was a Lead Author for the AR5, Chapter 12 (Long-term Climate Change: Projections, Commitments and Irreversibility).

Professor Gutowski was involved with the founding of CORDEX, first as a member of the Task Force on Regional Climate Downscaling that operated under the World Climate Research Programme (WCRP), starting in 2008.  He then became a member of the CORDEX Science Advisory Team (SAT) when the SAT replaced the Task Force at the end of its mandate.  He became a Co-Chair of the SAT in 2013 and served until his term ended at the end of 2019. He says: “CORDEX has played and continues to play an important role in guiding, organizing and promoting regional climate research around the world.  The organizational framework of CORDEX simulations has promoted international regional collaborations that have advanced regional climate modeling in many countries. The WCRP endorsement of CORDEX as one of its key programs has meant that those seeking support in their home countries have an authoritative backing to their efforts. The framework has also provided a common foundation for all of these efforts that has allowed many others to use CORDEX simulations in multi-model analyses. CORDEX continues to guide the development of regional modeling of climate by its efforts to coordinate further advances in regional modeling. This coordination is especially vital for the contributions of CORDEX to programs such as the IPCC.”’

William J. Gutowski Jr graduated from Yale University in 1976, Magna Cum Laude, with a B.S. in Astronomy and Physics and received his Ph.D. in Meteorology from MIT in 1984.  After working for a few years at a research firm in Cambridge, Massachusetts, USA, he joined the faculty of the Department of Geological and Atmospheric Sciences at Iowa State University, where he has been ever since, rising through the ranks to full Professor in 2000.  His research focuses on the dynamics of the hydrologic cycle, regional climate and weather and climate extremes. A highlight for him of this work is that it has fostered significant collaborations with fellow scientists around the world, especially in Africa, East Asia and the Arctic. In addition to his CORDEX and IPCC service, he has been an Editor of the Journal of Hydrometeorology, and also served on two review panels of the U.S. National Academy of Sciences (The Potential Impacts of Climate Change on U.S. Transportation, 2008; Challenges and Opportunities in the Hydrologic Sciences, 2012).  In 2017, he became an Honorary Professor in the Dept. of Environmental and Geographical Sciences, University of Cape Town, in recognition of his various contributions to the advancement of African climate science.  In 2017, he also became a Fellow of the American Meteorological Society.

This is the first of a series of presentations of IPCC AR6 authors from the CORDEX community that will be published at the CORDEX website. You can read more about them here
