Carbon rift is a theory attributing the input and output of carbon into the environment to human capitalistic systems. This is a derivative of Karl Marx's concept of metabolic rift. In practical terms, increased commodity production demands that greater levels of carbon dioxide (or CO2) be emitted into the biosphere via fossil fuel consumption. Carbon rift theory states that this ultimately disrupts the natural carbon cycle and that this "rift" has adverse effects on nearly every aspect of life. Many of the specifics regarding how this metabolic carbon rift interacts with capitalism are proposed by Brett Clark and Richard York in a 2005 article titled "Carbon Metabolism: Global capitalism, climate change, and the biospheric rift" in the journal Theory and Society. [1] Researchers such as Jean P. Sapinski of the University of Oregon claim that, despite increased interest in closing the carbon rift, it is projected that as long as capitalism continues, there is little hope of reducing the rift. [2]
Both deforestation and the emission of greenhouse gases have been linked to increased atmospheric CO2 levels. [3] [4] Carbon rift theory states that these are the result of human production through capitalistic systems. There are proposed solutions to climate change such as geoengineering proposed in the December 2015 Paris Agreement. [5] However, some argue that the capitalist mode of production is at fault for the emission of greenhouse gas and that solutions must be found to this issue before climate change itself can be addressed. [6]
Carbon rift theory shouldn't be confused with alternative explanations for climate change, which attribute the causes of the climate change to factors independent of human activity. Such explanations include the Chaotic Solar System Theory and that increased water vapor is responsible for climate change. [7] Capitalism and human activity are not mutually exclusive explanations for climate change, because capitalism is a form of organization of human societies.
Carbon rift is a result of CO2 gas being released into the environment by human sources, with the theory focusing specifically on capitalistic ones. In 2014, fossil fuel consumption resulted in nearly 36 billion metric tons of CO2 finding its way into natural sinks such as the atmosphere, land, and oceans. [4] This transfer of carbon from the burning of fossil fuels into the biosphere is the primary human-driven cause of greenhouse gas emissions and is closely related to the unchecked behavior of capitalism.
Another contributing factor to carbon rift is the continual deforestation of the Earth's forests. In doing so, humankind is not only releasing carbon into the biosphere but removing one of the primary ways that carbon is naturally re-absorbed into the carbon cycle. Deforestation can both be tied to having large effects on greenhouse gas emissions (specifically, carbon dioxide) [3] and to capitalism's continual disregard for its use of the truly limited resource represented by the forests. [8] Thus, we have a tie between capitalism, deforestation, and carbon. This is the metabolic pathway defined by carbon rift.
As the carbon rift continues to grow, the ecosystems of the biosphere continue to experience detrimental effects. One of the readily observable examples is the acidification of the world's oceans. This occurs when carbon dioxide is absorbed by seawater, lowering its pH. Since the start of the Industrial Revolution, which Marx explicitly ties to capitalism, oceans have experienced a 30% increase in acidity. [9] This acidification and resulting calcification of biological organisms are in part responsible for a decline of fishing as an industry and viable food source. [10] The enlarging carbon rift could result in poorer conditions for human society over time.
Carbon rift plays into a larger discussion of climate change caused by humans—a topic with stark political division. In the United States, the right end of the political spectrum tends to either deny/downplay climate change or attribute it to non-human causes, while people on the left stress the dangerous effects it has on the planet and society. [11] While the theory of carbon rift is not particularly well-known, these political divisions transfer to opinions on carbon rift because the theory operates under the belief that reliance on capitalist modes of production is the cause of increased carbon dioxide emissions.
The small amount of political and economic analysis that has been done on carbon rift discusses the theory’s relation to geoengineering. While geoengineering is still in the development stage as both a topic and solution to climate change, the December 2015 Paris Agreement highlighted “negative emissions technologies”. [12] These technologies aim to either “remove carbon dioxide from the atmosphere” or “reduce the amount of solar radiation that hits the earth’s surface. [5]
Some scientists and advocacy groups warn that geoengineering will have dangerous, irreversible effects on human society. [13] Furthermore, there is no way to fully test the accuracy of these technologies before launch, making the risk even greater. The 2013 film Snowpiercer offers a grim, politicized portrayal of the possible negative effects of climate engineering. However, other researchers support the develop of such technologies, as they believe their necessity is inevitable. These researchers claim that the climate of capitalistic growth will not falter and greenhouse gas emissions will continue to rise.
Critics of geoengineering emphasize that development of such technologies does not address the cause of carbon rift. Jean Sapinski from the University of Oregon defines the root cause as the “capitalist mode of production and the growth imperative it entails”. [14] The extent of carbon rift relates directly to the dominant economic system and the political institutions that reinforce said system. [6] Essentially, those who find fault in the capitalist system are more likely to believe carbon rift cannot be treated effectively without tackling capitalism first.
Carbon rift theory, as a subtopic of both Marxist metabolic theory and climate change, has inherited dissenting viewpoints from both its parent topics. Detractors claim exactly the opposite of carbon rift theory: human production does not have an appreciable effect on the carbon emissions in the biosphere. Since carbon rift theory has not yet made it into the mainstream lexicon, it is not often attacked directly by its detractors, but its concepts are. A notable individual that believes that climate change and human carbon emissions are unrelated is Patrick Moore, of Greenpeace fame. Other theories that explain the growing carbon rift (but exclude capitalism as a contributing factor) are the Chaotic Solar System theory, [7] the claim that carbon is wrongly blamed for the greenhouse effects of water vapor [15] and that the sun is causing global warming. These together are referred to as Non-Consensus views, and lack reliable scientific evidence.
The greenhouse effect occurs when greenhouse gases in a planet's atmosphere cause some of the heat radiated from the planet's surface to build up at the planet's surface. This process happens because stars emit shortwave radiation that passes through greenhouse gases, but planets emit longwave radiation that is partly absorbed by greenhouse gases. That difference reduces the rate at which a planet can cool off in response to being warmed by its host star. Adding to greenhouse gases further reduces the rate a planet emits radiation to space, raising its average surface temperature.
There is a strong scientific consensus that the Earth is warming and that this warming is mainly caused by human activities. This consensus is supported by various studies of scientists' opinions and by position statements of scientific organizations, many of which explicitly agree with the Intergovernmental Panel on Climate Change (IPCC) synthesis reports.
This glossary of climate change is a list of definitions of terms and concepts relevant to climate change, global warming, and related topics.
Climate engineering is a term used for both carbon dioxide removal and solar radiation management, also called solar geoengineering, when applied at a planetary scale. However, they have very different geophysical characteristics which is why the Intergovernmental Panel on Climate Change no longer uses this overarching term. Carbon dioxide removal approaches are part of climate change mitigation. Solar geoengineering involves reflecting some sunlight back to space. All forms of geoengineering are not a standalone solution to climate change, but need to be coupled with other forms of climate change mitigation. Another approach to geoengineering is to increase the Earth's thermal emittance through passive radiative cooling.
Metabolic rift is a theory of ecological crisis tendencies under the capitalism that sociologist John Bellamy Foster ascribes to Karl Marx. Quoting Marx, Foster defines this as the "irreparable rift in the interdependent process of social metabolism". Foster argues that Marx theorized a rupture in the metabolic interaction between humanity and the rest of nature emanating from capitalist agricultural production and the growing division between town and country.
Land use, land-use change, and forestry (LULUCF), also referred to as Forestry and other land use (FOLU) or Agriculture, Forestry and Other Land Use (AFOLU), is defined as a "greenhouse gas inventory sector that covers emissions and removals of greenhouse gases resulting from direct human-induced land use such as settlements and commercial uses, land-use change, and forestry activities."
Anthropogenic metabolism, also referred to as metabolism of the anthroposphere, is a term used in industrial ecology, material flow analysis, and waste management to describe the material and energy turnover of human society. It emerges from the application of systems thinking to the industrial and other man-made activities and it is a central concept of sustainable development. In modern societies, the bulk of anthropogenic (man-made) material flows is related to one of the following activities: sanitation, transportation, habitation, and communication, which were "of little metabolic significance in prehistoric times". Global man-made stocks of steel in buildings, infrastructure, and vehicles, for example, amount to about 25 Gigatonnes, a figure that is surpassed only by construction materials such as concrete. Sustainable development is closely linked to the design of a sustainable anthropogenic metabolism, which will entail substantial changes in the energy and material turnover of the different human activities. Anthropogenic metabolism can be seen as synonymous to social or socioeconomic metabolism. It comprises both industrial metabolism and urban metabolism.
Greenhouse gas (GHG) emissions from human activities intensify the greenhouse effect. This contributes to climate change. Carbon dioxide, from burning fossil fuels such as coal, oil, and natural gas, is one of the most important factors in causing climate change. The largest emitters are China followed by the United States. The United States has higher emissions per capita. The main producers fueling the emissions globally are large oil and gas companies. Emissions from human activities have increased atmospheric carbon dioxide by about 50% over pre-industrial levels. The growing levels of emissions have varied, but have been consistent among all greenhouse gases. Emissions in the 2010s averaged 56 billion tons a year, higher than any decade before. Total cumulative emissions from 1870 to 2017 were 425±20 GtC from fossil fuels and industry, and 180±60 GtC from land use change. Land-use change, such as deforestation, caused about 31% of cumulative emissions over 1870–2017, coal 32%, oil 25%, and gas 10%.
In Earth's atmosphere, carbon dioxide is a trace gas that plays an integral part in the greenhouse effect, carbon cycle, photosynthesis and oceanic carbon cycle. It is one of several greenhouse gases in the atmosphere of Earth. The current global average concentration of CO2 in the atmosphere is 421 ppm as of May 2022 (0.04%). This is an increase of 50% since the start of the Industrial Revolution, up from 280 ppm during the 10,000 years prior to the mid-18th century. The increase is due to human activity. Burning fossil fuels is the main cause of these increased CO2 concentrations and also the main cause of climate change. Other large anthropogenic sources include cement production, deforestation, and biomass burning.
This is a list of climate change topics.
Solar geoengineering, or solar radiation modification (SRM), is a type of climate engineering in which sunlight would be reflected back to outer space to limit or offset human-caused climate change. There are multiple potential approaches, with stratospheric aerosol injection (SAI) being the most-studied method, followed by marine cloud brightening (MCB). Other methods have been proposed, including a variety of space-based approaches, but they are generally considered less viable, and are not taken seriously by the Intergovernmental Panel on Climate Change. SRM methods could have a rapid cooling effect on atmospheric temperature, but if the intervention were to suddenly stop for any reason, the cooling would soon stop as well. It is estimated that the cooling impact from SAI would cease 1–3 years after the last aerosol injection, while the impact from marine cloud brightening would disappear in just 10 days. Contrastingly, once any carbon dioxide is added to the atmosphere and not removed, its warming impact does not decrease for a century, and some of it will persist for hundreds to thousands of years. As such, solar geoengineering is not a substitute for reducing greenhouse gas emissions but would act as a temporary measure to limit warming while emissions of greenhouse gases are reduced and carbon dioxide is removed.
Greenhouse gases are the gases in the atmosphere that raise the surface temperature of planets such as the Earth. What distinguishes them from other gases is that they absorb the wavelengths of radiation that a planet emits, resulting in the greenhouse effect. The Earth is warmed by sunlight, causing its surface to radiate heat, which is then mostly absorbed by water vapor (H2O), carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and ozone (O3). Without greenhouse gases, the average temperature of Earth's surface would be about −18 °C (0 °F), rather than the present average of 15 °C (59 °F).
The history of the scientific discovery of climate change began in the early 19th century when ice ages and other natural changes in paleoclimate were first suspected and the natural greenhouse effect was first identified. In the late 19th century, scientists first argued that human emissions of greenhouse gases could change Earth's energy balance and climate. Many other theories of climate change were advanced, involving forces from volcanism to solar variation. In the 1960s, the evidence for the warming effect of carbon dioxide gas became increasingly convincing. Some scientists also pointed out that human activities that generated atmospheric aerosols could have cooling effects as well.
The atmospheric carbon cycle accounts for the exchange of gaseous carbon compounds, primarily carbon dioxide, between Earth's atmosphere, the oceans, and the terrestrial biosphere. It is one of the faster components of the planet's overall carbon cycle, supporting the exchange of more than 200 billion tons of carbon in and out of the atmosphere throughout the course of each year. Atmospheric concentrations of CO2 remain stable over longer timescales only when there exists a balance between these two flows. Methane, Carbon monoxide (CO), and other man-made compounds are present in smaller concentrations and are also part of the atmospheric carbon cycle.
Deforestation is a primary contributor to climate change, and climate change affects forests. Land use changes, especially in the form of deforestation, are the second largest anthropogenic source of atmospheric carbon dioxide emissions, after fossil fuel combustion. Greenhouse gases are emitted during combustion of forest biomass and decomposition of remaining plant material and soil carbon. Global models and national greenhouse gas inventories give similar results for deforestation emissions. As of 2019, deforestation is responsible for about 11% of global greenhouse gas emissions. Carbon emissions from tropical deforestation are accelerating. Growing forests are a carbon sink with additional potential to mitigate the effects of climate change. Some of the effects of climate change, such as more wildfires, insect outbreaks, invasive species, and storms are factors that increase deforestation.
The amount of greenhouse gas emissions from agriculture is significant: The agriculture, forestry and land use sector contribute between 13% and 21% of global greenhouse gas emissions. Agriculture contributes towards climate change through direct greenhouse gas emissions and by the conversion of non-agricultural land such as forests into agricultural land. Emissions of nitrous oxide and methane make up over half of total greenhouse gas emission from agriculture. Animal husbandry is a major source of greenhouse gas emissions.
