Industrial civilization headed for 'irreversible collapse'?

8. The one the article is based on is a different one?

Then why is the para you cite a direct quote from the 2012 paper?

As to what is said about it in the paper:

Technological change can raise the efficiency of resource use, but it also tends to raise both per capita resource consumption and the scale of resource of extraction, such that, absent policy effects, the increases in consumption often compensate for the increased efficiency of resource use. These are associated with the phenomena referred to as the Jevon’s Paradox, and the “Rebound Effect” [Polimeni et al., 2008; Greening et al., 2000]. For example, an increase in vehicle fuel- efficiency technology tends to enable increased per capita vehicle miles driven, heavier cars, and higher average speeds, which then negate the gains from the increased fuel-efficiency. The extent of these effects varies, but in this initial model, we assume that the effects of these trends tend to cancel each other out. In future versions, the rates of these trends could be adjusted in either direction.

So they bring it up as an (invalid) excuse to simplify their modeling through the elimination of the effects of energy efficiency. i say invalid because we know conclusively that the forces in the example they use don't come close to canceling each other out. Neither do those forces act differently writ large.
