The nextGEMS data is aligned with the Climate Change Adaptation Digital Twin. The DestinE Digital Twin for Climate Change Adaptation (Climate DT) supports adaptation activities by providing innovative climate information on multi-decadal timescales, globally, at scales at which many impacts of climate change are observed. It combines cutting-edge global Earth-system models, impact-sector applications and observations into a unified framework to provide global climate projections and impact-sector information on multi-decadal timescales (1990 to ~2050), at very high spatial resolutions (5 to 10 km).
The Climate DT represents the first ever attempt to operationalise the production of global multi-decadal climate projections, leveraging the world-leading supercomputing facilities of the EuroHPC Joint Undertaking along with some of the leading European climate models. A concise overview of what the Climate DT aims to achieve, and of the different concepts essential for an understanding of the Digital Twin’s characteristics, is included in the [Climate DT factsheet](https://destine.ecmwf.int/wp-content/uploads/2024/06/2024.06.07_Climate…)
## Historical Simulation
Starting in 1990, the forcing follows observed changes in greenhouse gases, aerosols etc. until 2020. The simulations are using standardised CMIP6 forcing. Historical simulations are essential for model evaluation and quality control as they allow a comparison to observations.
## Models
The Climate DT exploits and further evolves a new generation of global storm-resolving and eddy-rich models built through a cooperative model development approach. For more information on models please click [here](https://destine.ecmwf.int/climate-change-adaptation-digital-twin-climat…)
## Simulations
The Climate DT team carries out several types of digital twin simulations on the EuroHPC supercomputers. Multi-decadal simulations are produced to cover the recent past (from 1990) and possible future evolutions of the climate up to 2050.
