This action is not primarily about raising awareness about climate – instead, assume that your player base has the awareness but since the problem is so big and so terrifying, most people (even climate activists) veil themselves in everyday denial, which is easy to do because everyone else does it and climate is an uncomfortable thing to talk about. So be uncomfortable. Show your audience that yes, even video games are talking about this now, so everyone should take it seriously.
Keep in mind that there is a difference between crisis awareness and despair. Doomism is a real threat.
