given the average, 150,000,000 deaths your % estimates produce. I would think this kind of cost in lives would warrant other costs paid to prevent it. Why should a cost such as this be dismissed as not worth any sacrifices to prevent?

probability. There maybe a 1% chance of the Earth being destroyed by a meteor in the next 100 years; that does not mean that an average of 60 million people are going to die of meteor strikes over the same period.

But you're not really addressing my point. I said very clearly that it's not a matter of the money in my book. It's a question of whether the threat of catastrophic climate change is real enough to warrant doing things that we wouldn't otherwise do, such as publicly-subsidize nuclear power, carbon sequestration and emissions trading schemes.

The costs really follow that discussion. If it's a big enough threat to warrant potentially ruining parts of the Earth for (functionally) ever, then I suppose, yeah, you're right, any cost is justified. I don't buy that it's a big enough threat to warrant taking the chance with nuclear, and therefore I also think that any potential measures should have to compete with other economic, environmental and social priorities for priority in terms of commitments of public resources.

being hit by a large meteor in the next 100 years, but that's besides the point. Yes in that situation 60 million is the average if you are figuring a population of 6,000,000,000. That doesn't mean 60 million die every time, but that's not what an average is. An average is the total divided by the number of terms. Since this is in percentage terms that would be 99 trials where no one dies, and one trial where 6,000,000,000 die. The total of the 100 trials is 6,000,000,000. Divided by 100, that is 60,000,000, the average. Maybe you're thinking of a median. That is the middle term, which in that case would be 0.

You don't have to talk about climate in particular. For a situation in which an average of 150,000,000 would die, would you be willing to make these sacrifices? If not, why?
