It is a common experience. Still last month I was interviewed by a journalist who started it asking me something like: "Don't you think that your views could turn out to be as wrong as the predictions of the Club of Rome in the 1970s?" The power of propaganda is truly awesome.

I have read M R Simmons summary "Revisiting the Club of Rome", also his book TITD.

Is the CERA Lynch/C.J Campbell saga not disimilar to this? Campbell is often accused of incorrectly predicting oil depletion dates. I,m not sure he actually did. He may have made reference to dates, but not necessarily predictions. From where I'm standing, the Simmons/Campbell camp may have the last "laugh" on this one. (It won't be funny)

Hi Ugo,

Thank you for the thoughtful post and starting this discussion. I have also had the experience, after a seminar, of hearing, "Your work is like Limits to Growth and the Club of Rome. They got it wrong."

In that context, it is interesting to look at nonrenewable resource use in the two scenarios from Limits to Growth, The 30-Year Update, shown below.

Figure 4-11 Scenario 1: A Reference Point

Figure 4-12: More Abundant Nonrenewable Resources

"Resources" in the graph means nonrenewable resources, and the top of the resources scale is given in Appendix 1 as 2x10^12. The units are not specified, but if we identify fossil fuels with nonrenewable resources, Ttoe is a reasonable fit. If this interpretation is wrong, someone please correct me. In Scenario 1, the ultimate would then be 1Ttoe, and the cumulative production would reach half of this by 2016. In Scenario 2, the ultimate would be 2Ttoe, and we would reach the half-way point by 2040. This range of years for the half-way point would probably be considered reasonable by many Oil Drum regulars.

There are 8 other Scenarios in the book, and they all use the higher ultimate. The nonrenewable resource use in most is similar to Scenario 2, but there are a wide range of responses for the other quantities.
