Multiscale regime shifts and planetary boundaries.
Life on Earth has repeatedly displayed abrupt and massive changes in the past, and there is no reason to expect that comparable planetary-scale regime shifts will not continue in the future. Different lines of evidence indicate that regime shifts occur when the climate or biosphere transgresses a tipping point. Whether human activities will trigger such a global event in the near future is unce...
متن کاملOn the System Properties of the Planetary Boundaries
THE PLANETARY BOUNDARIES Rockström et al. (2009) identified a set of critical sustainability issues where perturbations resulting from human activities present a risk of unacceptable global environmental change. They attempted to quantify a boundary level for each one, using the range of variability observed during the Holocene as the marker for the safe operating space for humanity. Together, ...
متن کاملPlanetary boundaries: Guiding human development on a changing planet
INTRODUCTION: There is an urgent need for a new paradigm that integrates the continued development of human societies and the maintenance of the Earth system (ES) in a resilient andaccommodating state. Theplanetaryboundary (PB) framework contributes to such a paradigm by providing a science-based analysis of the risk that human perturbations will destabilize the ES at the planetary scale. Here,...
متن کاملPlanetary Boundaries: Exploring the Safe Operating Space for Humanity
Anthropogenic pressures on the Earth System have reached a scale where abrupt global environmental change can no longer be excluded. We propose a new approach to global sustainability in which we define planetary boundaries within which we expect that humanity can operate safely. Transgressing one or more planetary boundaries may be deleterious or even catastrophic due to the risk of crossing t...
متن کاملSustainability. Planetary boundaries: guiding human development on a changing planet.
The planetary boundaries framework defines a safe operating space for humanity based on the intrinsic biophysical processes that regulate the stability of the Earth system. Here, we revise and update the planetary boundary framework, with a focus on the underpinning biophysical science, based on targeted input from expert research communities and on more general scientific advances over the pas...
