I just interpreted them as world background:[o]They appear to be ads for haven leadership summits, with numbers probably indicating the number of years since the plague started. The slogans show the evolution of their thinking.
A New Hope
In year 4 of the plague, the haven leaders are still optimistic and see themselves in a position to save the world.
All Together
As the plague drags on with no end in sight, the message changes from one of optimism to one of perseverance. The haven resources are strained and they need everyone to chip in.

We've lost contact with the havens outside the Atlantic. But we still have 3 havens! Look at everything we can still do, even with only 3 havens!
Let's Go
