Tipping towards the unknown

Researchers propose critical planetary boundaries, transgressing them could be catastrophic. But there is hope.

New approaches are needed to help humanity deal with climate change and other global environmental threats that lie ahead in the 21st century. A group of 28 internationally renowned scientists propose that global biophysical boundaries, identified on the basis of the scientific understanding of the Earth System, can define a safe planetary operating space that will allow humanity to continue to develop and thrive for generations to come.

This new approach to sustainable development was conveyed in Nature and Ecology and Society where the scientists have made a first attempt to identify and quantify a set of nine planetary boundaries.
