The safe landing climate is focusing on multidecadal to millennial timescales, organised in 5 themes & Working Groups:

Safe landing pathways (CC scenarios); Understanding HRES events (regimes shift, compound events); Perturbed Carbon cycle (CO2); Water resources (eg. deforestation); Sea Level Rise .

A GEWEX Newsletter article describes the focus. 

Digital Earth lighthouse focus on Global & Regional information on past, present, future. DE will link existing large scale programmes (& investments). Three main themes & WGs in DE:

1. Fully coupled km scale regional & global (an opportunity for seamlessness between systems, thanks to overlapping resolutions). Regions focus to analyse the DE output (South America, Arctic, connect on RHP) Lead: Cathy Hohenegger (MPI).
   A NCAR workshop on 3-7 October 2022 Boulder (km-scale ESM) 
2. Data assimilation for climate (reanalyses, although most are built in NWP context more than climate, exception NASA built for climate apps). Lead: Aneesh Subramanian (U Colorado)
   A NCAR workshop on 19-20 May (DA4Climate, after US Clivar meeting)
3. Beyond Physical Earth System (include human interactions & impacts). Links to RHP (need co-funding of agencies) & ISIMIP (Inter-Sectoral-Impact) are important. Lead: Andreas Prein (NCAR)

Comment: DE could/should push to endorse, re-groupe & link all storm resolving projects (in EU Nextgems (& Dyamond), Destine Programme, in US, AU).

Comment: A way to overcome initial aversion to DE could be to show added value of new generation of DE models will do (precipitation & hydrological extremes, clouds, wind) to show how they fit the needs.

Comment: Links to ESMO (Lead: Susann Tegtmeier & Cath Senior) are going to be important to benefit from overlaps.

Explaining & Predicting lighthouse is focusing on the science that enable the design and deployment of integrated capability for quantitative evaluation (observations, early warning, prediction of Earth System changes) at multi-annual to decadal timescales. Three themes & WGs:

1. Observations, modelling, optimal estimation systems 
2. integration of attribution, prediction, projection (anthropogenic & natural). Link to the A2D (Annual to Decadal Outlook), and the the World Weather Attribution Centre (
   WCRP workshop on Attribution Sept 2021
   Co-lead: Doug Smith
3. hazard assessment (different classes of hazard will be considered, with focus on multi-annual)

RIFS lighthouse is organised in 4 clusters (understanding regional, ...).

RIFS will link with the RHP & GLASS panels, and link to Lighthouses.

RIFS interfaces with CORDEX, and help focus climate change scenarios of farm-scales.

RIFS is completing the chain from GHP/RHP down to users, with elements of social science, socio-economic, communication, impact.

MCR (My Climate Risk) lighthouse is getting into a more mature state. Science plan consolidated. A bottom-up approach to local assessment of climate risk is embraced with people focus (see Rodriguez & Sheperd 2022).

Risk impact is at the interception of hazards, vulnerability and exposure. MCR will adopt the narrative of case studies.
