1. The Greens win the argument. We pass Kyoto, ride bicycles, tax methane and cripple the world’s economy.

2. The solar minimum predicted by many solar scientists occurs, and the earth cools several degrees even though CO2 levels continue to rise.

3. Vast expanses of American, Canadian, Ukrainian, Australian and Argentinean farmland become new Siberias. World hunger increases drastically and even some Americans face starvation. Food riots are a common occurence.

4. The Greens attempt to escape wrath of the angry mobs with pitchforks and torches. Many suffer the fate of witches in the Middle Ages.
