When i saw this diagram in a book, i thought it was a great illustration of the different results that might occur from no action (left wheel) and taking climate action (right wheel). After all, climate projections are complicated and involve a range of possible scenarios - but taking climate action improves our odds.
Then i visited the website and found it was also a game. There you can click to spin to Greenhouse Roulette wheel and compare the future with and without climate action. Being statistically-minded i did 100 spins, and the website graphs the results.
Another good way of demonstrating that climate change will happen, but taking action can greatly reduce the damage.
