Multiple studies demonstrate that earth system models are widely used and capable tools for simulating future climate change trajectories and their associated environmental impacts.
The claim states that open-source earth system models simulate future climate change trajectories. The retrieved literature features numerous peer-reviewed studies (e.g., papers 0, 1, 2, 6, and 8) utilizing global and regional earth system models to simulate and project future climate scenarios, carbon cycles, and hydroclimatic trajectories. There is no evidence refuting the claim. Therefore, the verdict is SUPPORTED.
