I did it myself, and found myself in Column B. For my worst case scenario of inaction, I assumed half of Antarctica and Greenland could melt in 100 years. For my worst case scenario of preventing global warming, I assumed that economic growth worldwide could slow from 4% to 2% annually.

In Column A, billions of people continue to starve to death because their incomes are 7 times less than what they should be. Storms and sea levels are just as they are today.

In Column B, we are either 7 times more wealthy than we are in Column A; or sea levels are 20 feet higher and hurricane zones are both wider and uninhabitable. Even if there is continuing worldwide devastation, as long as we can offset it with less than 50 trillion of today's dollars per year, we are better off--even in the worst case scenario.
