  2. Carbon dioxide in Earth's atmosphere - Wikipedia

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

    Since the start of the Industrial Revolution, atmospheric CO 2 concentration have been increasing, causing global warming and ocean acidification. [12] In October 2023 the average level of CO 2 in Earth's atmosphere, adjusted for seasonal variation, was 422.17 parts per million by volume (ppm). [13]

    Atmospheric carbon dioxide (CO 2) concentrations from 1958 to 2023. The Keeling Curve is a graph of the annual variation and overall accumulation of carbon dioxide in the Earth's atmosphere based on continuous measurements taken at the Mauna Loa Observatory on the island of Hawaii from 1958 to the present day.

  7. Effects of climate change on oceans - Wikipedia

    en.wikipedia.org/wiki/Effects_of_climate_change...

    Carbon dioxide and methane are examples of greenhouse gases. The additional greenhouse effect leads to ocean warming because the ocean takes up most of the additional heat in the climate system. [3] The ocean also absorbs some of the extra carbon dioxide that is in the atmosphere. This causes the pH value of the seawater to drop. [4]

  8. Greenhouse and icehouse Earth - Wikipedia

    en.wikipedia.org/wiki/Greenhouse_and_icehouse_Earth

    A "greenhouse Earth" is a period during which no continental glaciers exist anywhere on the planet. [6] Additionally, the levels of carbon dioxide and other greenhouse gases (such as water vapor and methane) are high, and sea surface temperatures (SSTs) range from 28 °C (82.4 °F) in the tropics to 0 °C (32 °F) in the polar regions.
