Charles Keeling, receiving the National Medal of Science from George W. Bush, in 2001 (from History of climate change science) Image 38 CO 2 sources and sinks since 1880. While there is little debate that excess carbon dioxide in the industrial era has mostly come from burning fossil fuels, the future strength of land and ocean carbon sinks is ...

Burning fossil fuels such as coal, petroleum, and natural gas is the leading cause of increased anthropogenic CO 2; deforestation is the second major cause. In 2010, 9.14 gigatonnes of carbon (GtC, equivalent to 33.5 gigatonnes of CO 2 or about 4.3 ppm in Earth's atmosphere) were released from fossil fuels and cement production worldwide ...
Countries are expected to emit a total 36.8 billion metric tons of CO2 from fossil fuels in 2023, a 1.1% increase from last year, the report by scientists from more than 90 institutions including ...
Burning fossil fuels: Burning oil, coal and gas is estimated to have emitted 37.4 billion tonnes of CO 2-eq in 2023. [34] The largest single source is coal-fired power stations, with 20% of greenhouse gases (GHG) as of 2021. [35] Land use change (mainly deforestation in the tropics) accounts for about a quarter of total anthropogenic GHG ...
The atmospheric concentration of carbon dioxide has increased by more than 30% since the start of the industrial age and is higher now than at any time in at least the past 650,000 years. This increase is a direct result of burning fossil fuels, broad-scale deforestation and other human activity.
CO 2 emissions primarily come from burning fossil fuels to provide energy for transport, manufacturing, heating, and electricity. [33] Additional CO 2 emissions come from deforestation and industrial processes, which include the CO 2 released by the chemical reactions for making cement, steel, aluminum, and fertiliser. [34]
Although methane leaks are significant, [8]: 52 the burning of fossil fuels is the main source of greenhouse gas emissions causing global warming and ocean acidification. Additionally, most air pollution deaths are due to fossil fuel particulates and noxious gases, and it is estimated that this costs over 3% of the global gross domestic product ...
