Slowing climate change is crucial. Navigating its challenges is only possible if it is understood as but one facet of planetary overshoot

The Anthropocene Requires a New Way of Thinking
The Anthropocene is a multidimensional challenge. Our future is more unpredictable than ever, with new phenomena like Category 5 megastorms, rapid species extinction, and the loss of polar ice. This change is irreversible.
NASA says levels of carbon dioxide (CO2) are higher than they have been at any time in the past 400,000 years—well before our species evolved—causing the atmosphere to warm.
The climate certainly has changed, but so too have other aspects of the planetary system.
Take the lithosphere: 193,000 human-made “inorganic crystalline compounds,” or what you and I might call “rocks,” now vastly outnumber Earth’s ~5,000 natural minerals, while 8.3 billion tons of plastics coat the land, water, and our internal organs.
Due to modern agribusiness techniques, so much topsoil is washing away, England has only about 60 more harvests left.
The biosphere is equally altered. Never has the planet been so crowded with human beings. In 1900, there were around 1.5 billion of us; in the 1960s, around 3 billion; today there are upwards of 7.4 billion.
Human beings and our domesticated animals comprise an astounding 97% of the total zoomass of terrestrial mammals, meaning wild creatures make up a miserly 3%.
Humans and our companion species occupy considerably more than half of the planet’s habitable land surface. Concerning the hydrosphere, fresh water renews itself at the rate of about 1% a year, but currently 21 out of 37 of the world’s major aquifers are being drawn down faster—in some cases much faster—than they can be replenished.
Alarming as each factor is on its own, the concept of the Anthropocene brings all these factors and others together.
The planet’s chemistry changed too. Warmer oceans interfere with the production of oxygen by phytoplankton, and some scientists predict with a rise of 6oC—which could happen as soon as 2100—this oxygen production could cease.
Our production of fixed nitrogen is five times higher than it was 60 years ago; in fact, Earth never had so much fixed nitrogen in its entire ~4.5-billion-year history.
Since World War II, synthetic chemical production increased more than thirtyfold. Of the more than 80,000 new chemicals, the United States Environmental Protection Agency has tested only about 200 for human health risks.
Alarming as each factor is on its own, the concept of the Anthropocene brings all these factors and others together. This is the only way we can understand Earth as a single reverberating system with feedback loops and tipping points we can’t yet predict.
The Anthropocene is interrelated systematicity presents not a problem, but a multidimensional predicament. A problem might be solved, often with a single technological tool produced by experts in a single field, but a predicament presents a challenging condition requiring resources and ideas of many kinds. We don’t solve predicaments; instead, we navigate through them.
Collaboration among scientists, policymakers, social scientists, humanists, and community leaders is key to contending with the Anthropocene.
Technology is important, but the hardest challenges will be about how to alter our political and economic systems.
Even the United Nations’ $24 million Millennium Ecosystem Assessment (2005) concluded our current systems are not up to the task: we need “significant changes in policies, institutions, and practices, which are not currently under way.”
The Danger of the One-Dimensional Thinking of Climate Change
So, are the techno-optimists, who believe most world problems can be solved by innovation, wrong?
The answer to this question is they are not so much wrong as misguided, in that they address a narrow issue in the narrowest terms. Most begin by gesturing toward the totality of environmental problems, but end by focusing on climate change alone. Sometimes climate change is further reduced to CO2 emissions to the exclusion of all other greenhouse gases, such as methane.
A favorite example of techno-optimists, such as economist Jeffrey Sachs, is substituting wind power for fossil fuels. Like others, he speaks in confident tones about “decoupling” economic growth from natural resources, contending “growth can continue while pressures on key resources (water, air, land, habitats of other species) and pollution are significantly reduced rather than increased,” by means of new technologies and market pricing.
In short, the techno-view is we can provide for the growing human population (expected to hit 8 billion in 2023) without destroying the ecosystem, without impoverishing future generations, and without bothering to transform our political and economic systems.
The status quo is fine, if we just tighten a few nuts and bolts.
Ahem. Let us look at this techno-optimism from the Anthropocene perspective.
Most industrial-scale wind turbines require rare earth metals sourced from China, which supplies about 90% of the world’s demand, and has a monopoly on some of these elements. Not only are the mines of China’s primary production site – the southeastern province of Jiangxi – being rapidly depleted, such mining entails shocking environmental and social costs.
According to investigative journalist Liu Hongqiao, “Research shows producing one ton of rare earth ore (in terms of rare earth oxides) produces 200 cubic meters of acidic wastewater. The production of the rare earths needed to meet China’s demand for wind turbines up to 2050 … will result in the release of 80 million cubic meters of wastewater.”
Once obtained, this ore must be transported and processed to make turbines. These turbines, once positioned, require maintenance, using more resources. Ultimately, though, they will end up as refuse, more trash on our trash-filled planet. There is nothing dematerialized or carbon-free about wind turbines if we look at the total picture.
Reducing our problem to climate change, then to CO2, and finally to measuring emissions only at the point of energy production is a dramatic misrepresentation of our dilemma. An Anthropocene perspective is needed to keep the totality of the predicament in view.
Slowing climate change is crucial, yet navigating its challenges is only possible if it is understood as one facet of planetary overshoot. The challenges of our altered, unpredictable Earth System cannot be met by technological tinkering within the very systems which pushed it over the edge in the first place.
There’s nothing for it but to roll up our sleeves and begin the hard work of transforming our political and economic systems with the aims of decency and resilience.
