German TV interviews CORDEX co-chair about the release of information sheets based on EURO-CORDEX simulations

The national German TV channel “ARD” contacted GERICS after hearing about the release of the  “Klimaausblicke” (Climate outlooks). In   the news item the reporter says that the data describing climate change in Germany has remained rather coarse in the past. This has now been changed by the publication of the analysis of climate data for each of the German counties by the Helmholtz-Zentrum Hereon / GERICS.

Altogether, 401   “Klimaausblicke” (Climate outlooks) can be downloaded for free to enable counties to prepare for the future.

Daniela Jacob says German counties now have access to detailed knowledge about possible future climate change, which needs to be considered for future planning.  No-one in Germany may say in the future: I didn’t know this.

The “Klimaausblicke” are based on 85 climate simulations (from the EURO-CORDEX community). Different scenarios, which depend on future climate mitigation, have been investigated,.

As an example, climate change information for different indices are given for the city of Karlsruhe located in South-Western Germany for RCP4.5 – representing a ‘middle’ emission concentration development.

Norbert Hacker, head of environment protection and work safety   in Karlsruhe, another guest on this news item talked about the consequences of present day climate change impacts and strategies, e.g., the dying of trees due to droughts and possible measures like watering trees in the city.

To sum up, it is mentioned that the “Klimaausblicke” are based on model simulations for this century carried out in a European effort. The spread shows that future climate change could be stronger or weaker dependent on our mitigation efforts.

After the release of “Klimaausblicke”, Daniela Jacob says that mitigating climate change is essential and that it is now obvious which consequences and related costs can be avoided by mitigating climate change.

The 42nd Session of the WCRP Joint Scientific Committee (JSC-42)

Today will be the last day of the the 42nd Session of the WCRP Joint Scientific Committee (JSC-42). It has so far been a week with interesting discussions on further scientific, coordinative and communicative development.

The aim has been to, among others, approve and  plan for the new Lighthouse Activities,  the new ‘CORE Projects’ “Earth System Modelling and Observations” and “Regional Climate Information for Society (RIfS)” and of course discuss progress and plans for the already established Core Projects, Grand Challenges and other major activities.

Daniela Jacob, co-chair of CORDEX Science Advisory Team (SAT), on behalf of the CORDEX community held a presentation on CORDEX latest achievements, upcoming activities and scientific priorities as well as CORDEX contributions to RIfS.  Please see the CORDEX report and presentation at JSC-42 for more details.

For more information on JSC-42, please visit https://www.wcrp-climate.org/jsc42-about.

We look forward to further strengthen the CORDEX community involvement and to continued and increased cooperation and exchange across WCRP activities!

Central/South America follow-up Online Paper-Writing Workshop

CORDEX Central America and South America are organizing a follow-up Online Paper-Writing Workshop on Regional Climate Modeling. The workshop will take place on May 3 and 5 at 17 UTC.

At the first online Paper Writing Workshop in November/December a number of collaboration groups consisting of students and early career researchers  were formed.  The groups choose a topic with focus on specific regional climate phenomena, outlined a work plan and time-line with the aim to submit a  paper with the scientific results. This follow-up workshop includes for instance update of status; project outline, data and methods and exchange of reviews between the groups.

 

WCRP Programme/Project offices meeting on 29 June

The WCRP International Project Offices (IPOs) and Joint Planning Staff (JPS) meet online regularly and the latest meeting was held on 29 June 2020, hosted by the CORDEX office.

Key activities and status were reported from all the IPOs during the telecon and the JPS reported on plans for the coming Joint Scientific Committee (JSC) meetings.

Iréne Lake, the CORDEX IPO director, presented some of the ongoing CORDEX activities:

  • CORDEX Experiment Design for dynamical and statistical downscaling of CMIP6.
  • CORDEX White Paper on the Future Regional Scientific Challenges for CORDEX.
  • CORDEX workshops on Capacity Development, Flagship Pilot Study meetings and other regional workshops planned for 2020 will either be held online in the fall or postponed until 2021.
  • Three longer online CORDEX Science Advisory Team-meetings were held 25 June, 30 June and 2 July to outline the way ahead.
  • There will shortly be a call for Flagship Pilot Studies announced.

 

Messages from the telecon included:

  • IPO staffs are gradually returning back to offices depending on the local situation.
  • All WCRP projects/programmes are outlining their roles in the new structure of the WCRP.
  • An extraordinary JSC session will be organised online in Nov/Dec of 2020
  • The JSC-42 will be organised in May/June 2021. Modality and venue are yet to be decided.
  • The WCRP calendar is being finalised with input from all IPOs.
  • Many activities are being postponed to 2021 due to Covid-19 and the possibility to have joint or back-to-back events was raised.
  • The next JPS and IPOs telecon will be organised in September and be chaired by GEWEX office.

CORDEX Climate Information at EGU’s Geoscience Meeting

Modelling the future climate on a regional scale requires both cooperation and computer power. Part of the work of CORDEX is to support countries that do not have the resources to produce regional climate information and to enable them to take advantage of global cooperation. At the big EGU Geoscience meeting, EGU2020, which took place on 4-8 May 2020, information produced within the CORDEX community was presented at several of the sessions.

The CORDEX (COordinated Regional Downscaling EXperiment) project office is located at SMHI in Sweden, and coordinates global cooperation for the development of climate scenarios and models on local and regional scales. CORDEX work is very important for the IPCC reports, including the forthcoming Assessment Report 6 (AR6).

Several of the sessions at EGU2020 discussed regional climate modelling from different aspects and therefore had strong links to CORDEX work.

Prioritising particularly vulnerable areas

CORDEX is about working towards sustainable societies by helping decision-makers and others to understand the risks associated with a changing climate. Studies based on CORDEX information show the importance of working with high resolution and with well-described physical processes.

– In this way we can respond to specific regional problems, for example by predicting precipitation more accurately in regions with complex topography. At the same time we can see changes in land use and regional climate and consequently improve our knowledge about planning and risk management in areas with low capacity, says Iréne Lake, Director of the International Project Office for CORDEX at SMHI.

Many of the analyses and experiments presented at the conference were based on CORDEX CORE results which are simulations carried out under specified minimum requirements, for example for resolution (grid spacing) and the time span. Since regional climate modelling requires huge amounts of computer power, the CORDEX network has suggested a priority list, including areas which are particularly vulnerable to changes in the climate.

The climate at the poles significantly affects the rest of the world, both socio-economically and ecologically. Regional climate models also play an important role here, to increase our understanding of the mechanisms affecting life environments, both historically and in the future.

Strengthening cooperation between experts and researchers

One of the goals of EGU is to create and strengthen the cooperation between experts and researchers from various disciplines. Representatives from both CORDEX and SMHI have been important contributors to several of the sessions. For example one of the CORDEX pilot projects on convective processes over Europe and the Mediterranean was highlighted during a session on atmospheric modelling, where the resolution needs to be high enough to describe the convection correctly.

CORDEX was also included in an Open Science session with the purpose of developing innovative tools and techniques to integrate, manage, evaluate and spread information for different systems for ESSP (Earth Systems Science Prediction).

Working for a sustainable future

– The challenges that we all experience and will face due to climate change permeate all parts of research and the community. EGU is an established and important forum for sharing experience and following the latest developments. SMHI and CORDEX are bringing new insights that can help us to be even better at contributing to a sustainable future for everyone living on our planet, says Iréne Lake.
