There are both natural and human sources of carbon dioxide emissions. Natural sources include decomposition, ocean release and respiration. Human sources come from activities like cement production, deforestation as well as the burning of fossil fuels like coal, oil and natural gas.
Due to human activities, the atmospheric concentration of carbon dioxide has been rising extensively since the Industrial Revolution and has now reached dangerous levels not seen in the last 3 million years.1 2 3 Human sources of carbon dioxide emissions are much smaller than natural emissions but they have upset the natural balance that existed for many thousands of years before the influence of humans.
This is because natural sinks remove around the same quantity of carbon dioxide from the atmosphere than are produced by natural sources.4 This had kept carbon dioxide levels balanced and in a safe range. But human sources of emissions have upset the natural balance by adding extra carbon dioxide to the atmosphere without removing any
Carbon Dioxide Emissions: Human Sources
Since the Industrial Revolution, human sources of carbon dioxide emissions have been growing. Human activities such as the burning of oil, coal and gas, as well as deforestation are the primary cause of the increased carbon dioxide concentrations in the atmosphere.
87 percent of all human-produced carbon dioxide emissions come from the burning of fossil fuels like coal, natural gas and oil. The remainder results from the clearing of forests and other land use changes (9%), as well as some industrial processes such as cement manufacturing (4%)

As an expert in environmental science and climate change, I bring a wealth of knowledge and experience to shed light on the concepts discussed in the provided article. My expertise is grounded in a comprehensive understanding of the intricate dynamics between human activities and their impact on carbon dioxide emissions, particularly in the context of the Industrial Revolution and its aftermath.
Let's delve into the key concepts outlined in the article:
-
Introduction: The article introduces the fundamental issue of carbon dioxide emissions, emphasizing the distinction between natural and human sources. It highlights that human activities, especially since the Industrial Revolution, have led to a significant rise in atmospheric carbon dioxide levels.
-
Structure: The structure of the article appears to follow a logical progression. It starts by distinguishing between natural and human sources of carbon dioxide emissions, subsequently delving into the consequences of this rise in atmospheric carbon dioxide levels.
-
Consortium and Partners: While not explicitly mentioned in the provided text, the terms "Consortium" and "Partners" might suggest collaborative efforts or organizations working on initiatives related to carbon dioxide emissions. These could involve research institutions, governmental bodies, or non-profit organizations addressing climate change.
-
News and Events: The article references specific events such as the "CHE final review" and the "CoCO2 kick-off meeting" held in January. These events likely pertain to initiatives or projects related to carbon dioxide emissions, possibly focusing on research, assessments, or collaborative efforts.
-
Resources: The term "Resources" suggests that there may be additional materials or information available for further exploration. This could include research papers, databases, or tools related to carbon dioxide emissions and climate change.
-
Data Portal: The mention of a "Data portal" implies the availability of a platform or repository where relevant data on carbon dioxide emissions, atmospheric concentrations, or related research findings can be accessed and analyzed.
-
Carbon Dioxide Emissions Overview: The article provides a concise overview of both natural and human sources of carbon dioxide emissions. Natural sources include decomposition, ocean release, and respiration, while human sources stem from activities like cement production, deforestation, and the burning of fossil fuels.
-
Historical Perspective: The article touches upon the historical aspect, noting that atmospheric carbon dioxide levels have reached dangerous levels not witnessed in the last 3 million years. This timeline places the issue within the broader context of Earth's geological history.
-
Industrial Revolution Impact: The article attributes the extensive rise in carbon dioxide levels to human activities since the Industrial Revolution. The burning of oil, coal, and gas, along with deforestation, is identified as the primary cause of increased atmospheric carbon dioxide concentrations.
-
Specific Percentages: The article quantifies human-produced carbon dioxide emissions, indicating that 87 percent is attributed to the burning of fossil fuels, 9 percent to land use changes, and 4 percent to industrial processes such as cement manufacturing.
In conclusion, my expertise allows me to navigate and interpret the nuances of the article, providing a comprehensive understanding of the intricate relationship between human activities and carbon dioxide emissions, and their implications for climate change.
