The climate change matter is quite difificult to understand. Especially the consequenses are rather diverse.
Now there is a game, called Climate Fresk. You can play with a group. This way you get more and more insight in the whole issue of climate change.
How Climate Fresk works: you need a facilitator and some people. The facilitator is trained and gives information about the climate and factors. Then he puts a stack of cards on the table, with captions like: “fossil fuels” and “temperature rises” and as a group you start to put them in causal order.
You can do it with your group of sailors. Playing it on the boat is perhaps too small, because you need a big table. But in your living room is fine. Or in the club, the classroom, wherever.
We played it. Everybody draws there own conclusions. What astonished me were the numerous effects on us, the human beings. Most of the nature will survive, like trees, insects, and fishes. No worries about the ecosystem, it is constantly adapting. but the adaptation will not be in favor of the mammals, and especially the humans. The effects on us are big, if not devastating.
