    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 ...

  4. CO2 content - Wikipedia

    en.wikipedia.org/wiki/CO2_content

    The value measures the total dissolved Carbon dioxide (CO 2) in blood. It is determined by combining the Bicarbonate (HCO − 3) and the partial pressure of CO 2 multiplied by a factor which estimates the amount of pure CO 2 that is dissolved in its natural form (usually 0.03). [citation needed] One given reference range is 24–32 mEq/L. [1]

    In most other nations, the reference ambient temperature for pollutant limits may be 0 °C or other values. Although ppmv and mg/m 3 have been used for the examples in all of the following sections, concentrations such as ppbv (i.e., parts per billion by volume), volume percent, mole percent and many others may also be used for gaseous pollutants.

    en.wikipedia.org/wiki/PCO2

    Carbon dioxide molecule.. pCO 2, pCO 2, or is the partial pressure of carbon dioxide (CO 2), often used in reference to blood but also used in meteorology, climate science, oceanography, and limnology to describe the fractional pressure of CO 2 as a function of its concentration in gas or dissolved phases.

  8. Representative Concentration Pathway - Wikipedia

    RCP 2.6 is a "very stringent" pathway. [6] According to the IPCC, RCP 2.6 requires that carbon dioxide (CO 2) emissions start declining by 2020 and go to zero by 2100.It also requires that methane emissions (CH 4) go to approximately half the CH 4 levels of 2020, and that sulphur dioxide (SO2) emissions decline to approximately 10% of those of 1980–1990.

    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 ...
