| - | '''Planetary boundaries''' is a concept involving Earth system processes which contain environmental boundaries, proposed in 2009 by a group of [[Earth system science|Earth system]] and [[environmental science|environmental scientists]] led by [[Johan Rockström]] from the [[Stockholm Resilience Centre]] and [[Will Steffen]] from the [[Australian National University]]. The group wanted to define a "safe operating space for humanity" for the international community, including governments at all levels, international organizations, civil society, the scientific community and the [[private sector]], as a precondition for [[sustainable development]]. The framework is based on scientific evidence that human actions since the [[Industrial Revolution]] have become the main driver of global environmental change. | + | '''Global change''' refers to planetary-scale changes in the [[Earth]] system. The system consists of the [[Terrestrial ecoregion|land]], [[oceans]], [[atmosphere]], [[polar region]]s, [[life]], the planet's natural cycles and deep Earth processes. These constituent parts influence one another. The Earth system now includes [[human society]], so global change also refers to large-scale changes in society and the subsequent effects on the environment. |

Global change refers to planetary-scale changes in the Earth system. The system consists of the land, oceans, atmosphere, polar regions, life, the planet's natural cycles and deep Earth processes. These constituent parts influence one another. The Earth system now includes human society, so global change also refers to large-scale changes in society and the subsequent effects on the environment.
