It's a reverse Pascal's Wager.

If you believe the eclipsologists, and they're wrong, you spent money to go on a vacation to Mexico or Niagara Falls or something, I think those were the big two. You probably had a great time, and the spending wasn't any different from a usual vacation, it just dictated where you'd go, not if you'd go. And of course, if they're right, you ALSO get a cool lightshow. If you don't believe them, either way, nothing happens except maybe you get startled for a few minutes if you happen to actually be in the totality path.

If you believe the climatologists, you MUST commit genocide. Earth is overpopulated, and only by killing the approximate entire populations of China and India can Earth be saved, and the timer to do it is far, FAR shorter than letting them die naturally. If they're wrong, you've killed BILLIONS. If they're right, YOU'VE STILL KILLED BILLIONS!

If you don't believe the climatologists... If they're wrong, you save money on everything you buy, and have a very good life. If they're right, then someone else, not you, three lifetimes after you die, will feel like moving to Canada because its climate is now nicer to live in than yours in Texas, while you STILL save money on everything you buy and have a higher standard of living. And of course, in both cases, you don't need to massacre billions of people.
