1. Transition Decades for Ocean Acidification in the California Current System

2. Observations: The California Current System is at particular risk of ocean acidification

3. Global models miss the acuteness of ocean acidification in coastal upwelling systems

4. High resolution regional simulations detect the acuteness of ocean acidification in the California Current System

5. The California Current System is also susceptible to the consequences of ocean acidification

6. When will the range of surface Ωaragonite diverge from the preindustrial or present-day variability ‘envelope’?

9. How does the intensity and duration of individual aragonite undersaturation events evolve?

10. Evolution of the intensity of undersaturation events in the benthic environment
