It is closely related to the younger scientific neologism "planetary boundaries." Both terms describe human impacts on the face of the Earth that are wider and deeper than previously recognized. Both also have an epochal meaning, suggesting as they do the end of the Holocene epoch (the period...
The planetary framework outlines two sub-boundaries for biogeochemical flows, specifically focusing on the biogeochemical cycles for N and P (ref.11). For the N cycle, the proposed proxy indicator is the intentional N fixation, which includes N fixation in fertilizer and from crop fixation. For ...
The Lunar Prospector data have demonstrated that KREEP-rich rocks tend to be found on the rims and boundaries of major lunar impact basins where there are surmised to have been exposed, dredged up, and dispersed as a result of these cataclysmic impact events. The most intriguing of the recent...
using the Planetary Boundaries theory. The nine different Planetary Boundaries i.e. climatic change, biodiversity loss, biogeochemical, ocean acidification, land use, freshwater availability, stratosphere ozone depletion, atmospheric aerosols

1.1. The planetary boundaries framework One of the main challenges in assessing the sustainability of consumption is the definition of a reference point, which enables the quantification of the environmental performance of the production and consumption system with respect to the Earth carrying capacity,...

There is a broad call to integrate planetary boundaries and life-cycle based reporting into accounting theory and reporting standards. Although many practitioners back this call, including insurers, shareholders with a long-term orientation, and company
The transparent sidewall is made of cast acrylic (thermal conductivity k = 0.19 W/m/K) and the top and bottom boundaries are T6061 aluminum (k = 167 W/m/K). A non-inductively wound, PID-controlled heat pad warms the bottom boundary to a fixed temperature (Tbot), while a ...
Interior structure models aim at calculating (1) the volumes and masses of major chemical reservoirs that contribute to the bulk composition; (2) the depths to chemical and rheological discontinuities and mineral phase boundaries; and (3) depth variations of pressure, temperature, density, and ...
