  2. Carbon dioxide in Earth's atmosphere - Wikipedia

    en.wikipedia.org/wiki/Carbon_dioxide_in_Earth's...

    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 three main greenhouse gases in the atmosphere of Earth. Water vapor is the primary greenhouse gas, as of 2010, contributing 50% of the greenhouse effect, followed by ...

    This is an accepted version of this page This is the latest accepted revision, reviewed on 17 September 2024. 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 ...

  4. Greenhouse gas emissions - Wikipedia

    en.wikipedia.org/wiki/Greenhouse_gas_emissions

    Greenhouse gas emissions. Annual carbon dioxide emissions per person (height of vertical bars) and per country (area of vertical bars) of the fifteen highest-emitting countries (1990-2018) [ 1 ] Greenhouse gas (GHG) emissions from human activities intensify the greenhouse effect. This contributes to climate change.

  5. History of climate change science - Wikipedia

    en.wikipedia.org/wiki/History_of_climate_change...

    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 ...

    en.wikipedia.org/wiki/Causes_of_climate_change

    The likely range of human-induced surface-level air warming by 2010–2019 compared to levels in 1850–1900 is 0.8 °C to 1.3 °C, with a best estimate of 1.07 °C. This is close to the observed overall warming during that time of 0.9 °C to 1.2 °C.

  7. Greenhouse effect - Wikipedia

    The planet Venus experienced a runaway greenhouse effect, resulting in an atmosphere which is 96% carbon dioxide, and a surface atmospheric pressure roughly the same as found 900 m (3,000 ft) underwater on Earth. Venus may have had water oceans, but they would have boiled off as the mean surface temperature rose to the current 735 K (462 °C ...

    The atmospheric levels of carbon dioxide are the highest they have been in at least 2 million years, [1]: 8 if not 3.2 million years. [ 2 ] : 11 The atmospheric levels of two other major greenhouse gases, methane and nitrous oxide , are the highest they have been in at least the past 800,000 years.
