(Santa Barbara, Calif.) New approaches are needed to help humanity deal with climate change and other global environmental threats that lie ahead in the 21st century, according to a group of 28 internationally renowned scientists.
The 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 is conveyed in the current issue of the scientific journal Nature. The authors have made a first attempt to identify and quantify a set of nine planetary boundaries, including climate change, freshwater use, biological diversity, and aerosol loading.
The research was performed by a working group at UC Santa Barbara's National Center for Ecological Analysis and Synthesis (NCEAS), in cooperation with the Stockholm Resilience Centre at Stockholm University.
One important strand of the research behind this article is based in the global project known as IHOPE. The goal of the Integrated History and future Of People on Earth (IHOPE) project is to understand the interactions of the environmental and human process over the ten to hundred millennia to determine how human and biophysical changes have contributed to Earth system dynamics. The IHOPE working group is assembled at NCEAS today.
The scientists emphasize that the rapid expansion of human activities since the industrial revolution has now generated a global geophysical force equivalent to some of the great forces of nature.
"We are entering the Anthropocene, a new geological era in which our activities are threatening the earth's capacity to regulate itself," said co-author Will Steffen, professor at the Australian National University (ANU) and director of the ANU Climate Change Institute. "We are beginning to push the planet o
