The medium projection, the one most commonly used, has world population reaching 9.2 billion by 2050.
Rather, they have used the same medium projection, with a narrower range of possibilities around it.
While these figures were for the scenario in which the prison population would increase the most, even the medium projection for June 2017 fell from 99,900 to 85,300.
These animations were auxiliary to his repertoire, an aside to his primary medium: projection mapping on buildings more specifically, world-renowned pieces of architecture.
Sums of these two curves provided a close approximation to the UN medium projection.
Thus, the UN medium projection requires more energy than is predicted to be available, as well as for that energy to be distributed much differently than it is distributed today.
After this time, which is well before the predicted leveling of population size, the global supply falls short of the amount needed to continue along the UN medium projection.
We calculated this amount, which we refer to as the implicit energy supply assumption of the UN medium projection, by breaking down the projection by developed and developing countries and determining the total energy supply needed to achieve the projected growth rate.
Using the optimistic energy scenario, this change produced a much slower rate of growth, concurrent with the UN medium projection until about 2025, at 8 billion people, at which point our trajectory departs from the UN's and continues to rise.
