CRESCENDO was heavily-involved in a highly-creative workshop on Model Evaluation at the Aspen Global Change Institute (AGCI) this summer (http://www.agci.org/event/17s2 ). The workshop was co-directed by Veronika Eyring and Peter Cox of CRESCENDO, in partnership with Peter Gleckler (Lawrence Livermore) and Greg Flato (Canadian Climate Centre). Its aims were closely aligned to some of the key goals of CRESCENDO, namely to ‘contribute to reducing the spread of climate projections by enabling more complete evaluation of model outputs against observations, and by identifying Emergent Constraints – observable aspects of the contemporary Earth System that are most closely related to future projections’.

This summer CRESCENDO supported the UKESM team (www.ukesm.ac.uk) and the National Centre for Atmospheric Science (NCAS) to participate at the Royal Society summer science exhibition (3 to 9 July 2017) in London, a unique opportunity to showcase the status of the UK Earth system modelling science and help the general […]

In May 23-24 2017, the European Commission initialised two events involving CRESCENDO in Brussels: The Project interim review after 18 months of improving our Earth System Models (ESMs), and a separate Modelling workshop with the title: Evaluating climate and Earth system models at the process level, co-organised by CRESCENDO in partnership with other three H2020 projects: PRIMAVERA, Blue-Action and APPLICATE. Both meetings were held at the headquarters of EASME (EU Executive Agency for Small and Medium-sized Enterprises).

CRESCENDO was invited to the ClimatEurope Festival – a celebratory conference of climate services work funded by the European Union through the Horizon H2020 programme. This was a fascinating introduction to climate services for me, an Earth System Modeller. It really showcased the range of work that is done based on the CMIP model results which CRESCENDO helps develop and run.

“Cooperation between Earth System Models and Integrated Assessment Models as done in CRESCENDO will help us to implement the Paris climate targets. It will provide insights on the efforts needed to implement these targets as well as the benefits”. This statement from Colin Jones, CRESCENDO Project Coordinator, was one of the most important take-home messages […]

CRESCENDO has teamed up with the White Rose Brussels to organise its 1st policy briefing at the European Parliament on Tuesday 28th February


Realizing the Paris Agreement – Pathways and benefits of limiting global warming to 1.5C


 

London MEP Seb Dance has kindly agreed to host us in the European Parliament for a topical policy briefing that will address the 1.5/2°C global warming target set out in the Paris Accord, and will emphasize the use of Earth system models for investigating possible pathways to limiting global warming to 1.5/2°C. This engaging event will also assess the socio-economic benefits of limiting warming to these levels compared to less ambitious targets.

30-31 Jan 2017, Hamburg, MPI-M (Geomatikum Building, Bundesstr. 55, room 1729)

Conveners: Victor Brovkin and Lena Boysen (MPI, Germany)

The meeting of CRESCENDO terrestrial modelling groups was dedicated to the preparation of experiments designed to quantify land use effect on climate. 20 scientists from 7 European ESM groups discussed new aspects of the land use change (LUC) dataset prepared for the historical CMIP6 simulation. This new LUC forcing is much more complex than it was for CMIP5. How could models with different land cover structure interpret LUC scenarios in a consistent way? For example, this new forcing includes rangeland as a new LUC class. Some models assume that rangelands are natural vegetation and ignore the new class, while others treat rangelands as pastures, which are cleaned of forests, and suppress fires etc. Another divergence issue is on sub-grid scale transitions. Several models use so-called gross transitions accounting for crop rotations within grid cell, while others use simplified net transitions. Gross transitions are more difficult to implement; however, they better reflect changes in the land carbon budget. These and other details of the LUC dataset and their usage in ESMs were intensely discussed in a Q&A telecon session with George Hurtt of the University of Maryland, head of the group developing the land use forcing for CMIP6.

15-16 November 2016, Ludwig-Maximilians-Universität München (LMU), Germany

Conveners: Veronika Eyring, Björn Brötz, Axel Lauer, Alexander Löw, Ben Müller, and Mattia Righi

The 2nd workshop on the technical development of the Earth System Model Evaluation Tool (ESMValTool) was held at the Ludwig-Maximilians-Universität München (LMU) in the Department of Geography from 15-16 November 2016. The ESMValTool is developed as a community system, open to both users and developers, hence encouraging open exchange of evaluation methods and results (Eyring et al., 2016c). This will facilitate and improve Earth System Model (ESM) evaluation beyond the state-of-the-art and aims at supporting model evaluation and development activities at individual modelling centres and within the Coupled Model Intercomparison Project (CMIP). It is envisaged to run the tool routinely on model output submitted to CMIP Phase 6 (CMIP6, Eyring et al. (2016a)), utilizing observations and reanalyses available through the Earth System Grid Federation (ESGF) in standard formats (obs4MIPs/ana4MIPs) or provided by the user.

ClimateChangeWeChange powered by the CRESCENDOschools Network is now live!

It is the new web portal to help you better understand our changing planet and the methodologies and process of building Earth system models (ESMs) and climates projections.

The CRESCENDOschools network has just started work on an exciting new goal of partnering some of our research institutes with nearby schools.  We will be working and interacting with 16-18 years old students to co-develop novel, educational and informative materials and activities on climate change and climate models. Three schools in Europe have already embarked on this new venture which will see students, teachers and researchers meeting up over the next year to work together on new ways to share project finding with the wider community and increase awareness and understanding about the science behind climate change.

27-29 Sept 2016, Rome, Italy

This year, CRESCENDO’s General Assembly was held by Project Partner CNR at its headquarters in Rome, Italy. Special thanks go to Jost von Hardenberg for acting as local organiser for this meeting. The annual meeting ran over two full days (27-28th sept) plus an extra day (29th Sept) with optional attendance dedicated to a half-day scoping meeting focused on “Potential CRESCENDO contributions to the 1.5/2C warming Special Report” with around 50 attendees. It was a very successful meeting with over 80 attendees from all CRESCENDO partners, plus one representative, Pier Luigi Vidale from the H2020 project PRIMAVERA and one representative, Wilfran Moufouma-Okia from the IPCC Working Group I.

All presentations from the meeting and full version of the meeting minutes and post-meeting survey results have now been made available on our Intranet (https://www.crescendoproject.eu/intranet/member-account-page/members-login-page/).
