  2. Greenhouse gas emissions - Wikipedia

    en.wikipedia.org/wiki/Greenhouse_gas_emissions

    Cement production (burning of fossil fuels) (4%) is estimated at 1.42 GtCO 2; Land-use change (LUC) is the imbalance of deforestation and reforestation. Estimations are very uncertain at 4.5 GtCO 2. Wildfires alone cause annual emissions of about 7 GtCO 2 [97] [98] Non-energy use of fuels, carbon losses in coke ovens, and flaring in crude oil ...

  3. Fossil fuel - Wikipedia

    en.wikipedia.org/wiki/Fossil_fuel

    Environmental pollution from fossil fuels impacts humans because particulates and other air pollution from fossil fuel combustion may cause illness and death when inhaled. These health effects include premature death, acute respiratory illness, aggravated asthma, chronic bronchitis and decreased lung function.

  4. Health and environmental impact of the petroleum industry

    en.wikipedia.org/wiki/Health_and_environmental...

    Deaths caused by use of fossil fuels such as oil (areas of rectangles in chart) greatly exceed those resulting from production of renewable energy (rectangles barely visible in chart). [ 45 ] Some harmful impacts of petroleum can be limited to the geographic locations where it is produced, consumed, and/or disposed.

  5. Causes of climate change - Wikipedia

    en.wikipedia.org/wiki/Causes_of_climate_change

    This phenomenon is popularly known as global dimming, [48] and is primarily attributed to sulfate aerosols produced by the combustion of fossil fuels with heavy sulfur concentrations like coal and bunker fuel. [9] Smaller contributions come from black carbon, organic carbon from combustion of fossil fuels and biofuels, and from anthropogenic dust.

  6. Carbon-based fuel - Wikipedia

    en.wikipedia.org/wiki/Carbon-based_fuel

    Carbon-based fuel is any fuel principally from the oxidation or burning of carbon.Carbon-based fuels are of two main kinds, biofuels and fossil fuels.Whereas biofuels are derived from recent-growth organic matter [1] and are typically harvested, as with logging of forests and cutting of corn, fossil fuels are of prehistoric origin [2] and are extracted from the ground, the principal fossil ...

    This is an accepted version of this page This is the latest accepted revision, reviewed on 10 February 2025. Gas in an atmosphere with certain absorption characteristics This article is about the physical properties of greenhouse gases. For how human activities are adding to greenhouse gases, see Greenhouse gas emissions. Greenhouse gases trap some of the heat that results when sunlight heats ...

  8. Carbon cycle - Wikipedia

    en.wikipedia.org/wiki/Carbon_cycle

    In a given year between 10 and 100 million tonnes of carbon moves around this slow cycle. This includes volcanoes returning geologic carbon directly to the atmosphere in the form of carbon dioxide. However, this is less than one percent of the carbon dioxide put into the atmosphere by burning fossil fuels. [2] [32] [37]

  9. Carbon sink - Wikipedia

    en.wikipedia.org/wiki/Carbon_sink

    An overarching term is carbon pool, which is all the places where carbon on Earth can be, i.e. the atmosphere, oceans, soil, florae, fossil fuel reservoirs and so forth. A carbon sink is a type of carbon pool that has the capability to take up more carbon from the atmosphere than it releases.
