Scientists are building a digital twin of the Earth to fight climate change

The digital double could be an important tool in preventing climate change.

  • The European Union has launched two programs to become climate neutral by 2050: Green Deal and Digital Strategy.
  • Alongside this, their 10-year Destination Earth initiative will involve creating a digital twin of the Earth to map climate development.
  • This digital model will also be used to predict how certain scenarios would affect Earth and create effective solutions against climate change.

To become climate neutral by 2050, the European Union launched two ambitious programs: Green Deal and Digital Strategy. As a key component of their successful implementation, climate scientists and computer scientists launched the Destination Earth initiative, which will start in mid-​2021 and is expected to run for up to ten years. During this period, a highly accurate digital model of the Earth is to be created, a digital twin of the Earth, to map climate development and extreme events as accurately as possible in space and time.

Observational data will be continuously incorporated into the digital twin in order to make the digital Earth model more accurate for monitoring the evolution and predict possible future trajectories. But in addition to the observation data conventionally used for weather and climate simulations, the researchers also want to integrate new data on relevant human activities into the model. The new Earth system model will represent virtually all processes on the Earth’s surface as realistically as possible, including the influence of humans on water, food, and energy management, and the processes in the physical Earth system.
