Abstract
The Safe Operating Space for Humanity is not fully characterized by the state values of Planetary Boundaries because not only does interaction among them matter, but more importantly the perturbation response capacity dimension is missing. We present a systems dynamics measure of this perturbation response capacity under the Antifragility framework. Here we define, for the first time, Planetary Antifragility as the changes of shortwave global albedo anomalies for the July months in the northern hemisphere from 1982 to 2010, which shows a net reduction of 47.63 %. This loss in Antifragility implies a compounding problem because human perturbations such as climate or land-use changes are increasing but at the same time, the planet is losing its capacity to respond to them.
Highlights
10 The seminal work "Planetary Boundaries: Exploring the Safe Operating Space for Humanity" by Rockström et al (2009)identified nine core biogeochemical processes, with Planetary Boundaries (PB) for each, within which the authors expect that humanity would operate safely.The central idea of their work is that transgressing one or more PB may lead to catastrophic planetary tipping point most likely incompatible with modern human organization or even with human survival.Despite PB has been widely accepted, there are some issues that remain open: (a) the authors recognize that PB 15 are not interdependent, as transgressing one may both shift the position of other boundaries and cause them to be transgressed, the individual threshold values of the Planetary Limits (LP) do not establish the true threshold configuration
