Humans Have Crossed 6 of 9 ‘Planetary Boundaries’
Scientists analyzed nine so-called planetary boundaries and found humans are currently transgressing six
Human activity is turning Earth into a world that may no longer adequately support the societies we’ve built, scientists warn in a new study charting whether and by how much we have surpassed nine “planetary boundaries.”
The analysis builds on a 2009 paper that first outlined nine planetary constraints that keep Earth’s environment similar to that of the world humans lived in during the preindustrial portion of the Holocene epoch. This period lasted for about the past 10,000 years, until the industrial revolution began and humans started burning large amounts of fossil fuels and sending heat-trapping greenhouse gases into the atmosphere. In the new research, published on Wednesday in Science Advances, researchers raise the alarm about what the potential consequences of this departure from humans’ baseline might be.
“It’s like blood pressure,” says Katherine Richardson, an earth systems scientist at the University of Copenhagen, who led the new research. “If your blood pressure is over 120 over 80, it’s not a guarantee that you’re going to have a heart attack, but it does raise the risk, and therefore we do what we can to bring it down.”
The new study marks the second update since the 2009 paper and the first time scientists have included numerical guideposts for each boundary—a very significant development. “What is novel about this paper is: it’s the first time that all nine boundaries have been quantified,” says Rak Kim, an environmental social scientist at Utrecht University in the Netherlands, who wasn’t involved in the new study.
