Say:

In this video, you’ll see another representation of how the invisible chemistry of the ocean is changing. The blue areas show plenty of carbonate available for animals to build their shells.

{Start video} As time passes and CO2 is added to the ocean, the color changes to orange, indicating that there is no longer enough carbonate for these animals.

Notes and Rationale:

This slide creates a transitional bridge between the microscopic scale of OA impacts on individual animals and the global scale of the problem.

This visualization is very short, so plan your timing with the narrative accordingly. Before you start playing the video, specifically point out blue and orange areas so that the audience knows what to look for when the animation begins.
