  2. Carbon dioxide in Earth's atmosphere - Wikipedia

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

    Carbon dioxide has unique long-term effects on climate change that are nearly "irreversible" for a thousand years after emissions stop (zero further emissions). The greenhouse gases methane and nitrous oxide do not persist over time in the same way as carbon dioxide. Even if human carbon dioxide emissions were to completely cease, atmospheric ...

  3. Carbon dioxide - Wikipedia

    en.wikipedia.org/wiki/Carbon_dioxide

    Carbon dioxide is the lasing medium in a carbon-dioxide laser, which is one of the earliest type of lasers. Carbon dioxide can be used as a means of controlling the pH of swimming pools, [139] by continuously adding gas to the water, thus keeping the pH from rising. Among the advantages of this is the avoidance of handling (more hazardous) acids.

  4. Atmospheric carbon cycle - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_carbon_cycle

    [26] The airborne fraction has been around 60% since the 1950s, indicating that about 60% of the new carbon dioxide in the atmosphere each year originated from human sources. [10] For clarity, this is not meant to suggest that 60% of the uptake of carbon dioxide into the atmosphere comes from human activity.

    The data only consider carbon dioxide emissions from the burning of fossil fuels and cement manufacture, but not emissions from land use, land-use change and forestry. [n 2] Over the last 150 years, estimated cumulative emissions from land use and land-use change represent approximately one-third of total cumulative anthropogenic CO 2 emissions ...

  6. Oceanic carbon cycle - Wikipedia

    en.wikipedia.org/wiki/Oceanic_carbon_cycle

    Carbon dioxide is absorbed from the atmosphere at the ocean's surface at an exchange rate which varies locally and with time [32] but on average, the oceans have a net absorption of around 2.9 Pg (equivalent to 2.9 billion metric tonnes) of carbon from atmospheric CO 2 per year. [33]

    SHARM EL-SHEIKH, Egypt (AP) — The world’s burning of coal, oil and natural gas this year is putting 1% more heat-trapping carbon dioxide in the air than last year, bad news for the fight ...

  8. Greenhouse gas emissions - Wikipedia

    en.wikipedia.org/wiki/Greenhouse_gas_emissions

    Carbon dioxide is the main greenhouse gas resulting from human activities. It accounts for more than half of warming. Methane (CH 4) emissions have almost the same short-term impact. [5] Nitrous oxide (N 2 O) and fluorinated gases (F-gases) play a lesser role in comparison. Emissions of carbon dioxide, methane and nitrous oxide in 2023 were all ...

    BRUSSELS/BERLIN (Reuters) -The vast majority of planet-warming carbon dioxide emissions since 2016 can be traced to a group of 57 fossil fuel and cement producers, researchers said on Thursday.
