8 questions

  1. Bistability of the Atlantic thermohaline circulation and its control by diapycnal diffusivity

  2. Robustness and real-world applicability of simulated Atlantic thermohaline-circulation changes: overturning multiple equilibria, rate-dependent weakening, and multi-century recovery

  3. Mechanism, time-scale controls, and real-world fidelity of the 40-80-year Greenland Sea-North Atlantic multidecadal climate oscillation (Delworth, Manabe and Stouffer, 1997)

  4. Anthropogenic collapse of the Atlantic meridional overturning circulation: real-world thresholds with ice-sheet meltwater, model-formulation robustness, and carbon-cycle consequences

  5. Reconciling the coupled ocean-atmosphere response to deglacial freshwater forcing with the Younger Dryas record: inter-model overturning stability and the origin of meltwater pulse 1A

  6. Is the collapsed 'off' state of the Atlantic meridional overturning circulation a physically realizable, stable equilibrium of the real ocean?

  7. Dynamical regimes of the Atlantic thermohaline circulation under glacial meltwater forcing and their reconciliation with palaeoceanographic proxies

  8. Constraining cloud feedback under global warming from the observed annual cycle of clouds and surface temperature
