Extended Data Fig. 2: Failed scenario 2, a modelled large increase in uplift (and thus erosion).

Panels a–g are parameter changes and panels h–p are key model results as detailed for Main Fig. 3. In all panels (apart from e, j and m) the black line is the model average and the grey band is the ±1σ. In panels m and p the blue line and band are from Main Fig. 2.
