2052: A Global Forecast for the Next Forty Years
There are three differences to the previous report. First, it does not describe a disaster scenario, but shows only trends. Secondly, it is to be read in the light of experience since 1972, namely, that all of humanity has responded to the report, but with a delay  of 20  to 40 years. Thirdly, it offers not only future scenarios, it makes concrete proposals on how the individual should respond to emerging developments.
