  2. Transient climate response to cumulative carbon emissions

    en.wikipedia.org/wiki/Transient_climate_response...

    ΔT = average global temperature change (°C) E T = cumulative carbon dioxide emissions (Tt C) ΔC A = change in atmospheric carbon (Tt C) and, 1Tt C = 3.7 Tt CO 2. TCRE can also be defined not in terms of temperature response to emitted carbon, but in terms of temperature response to the change in radiative forcing: [10]

    D-carbon: D-carbon was proposed by theorists in 2018. [34] D-carbon is an orthorhombic sp 3 carbon allotrope (6 atoms per cell). Total-energy calculations demonstrate that D-carbon is energetically more favorable than the previously proposed T 6 structure (with 6 atoms per cell) as well as many others.

  4. Climate change - Wikipedia

    en.wikipedia.org/wiki/Climate_change

    Climate change can also be used more broadly to include changes to the climate that have happened throughout Earth's history. [32] Global warming—used as early as 1975 [33] —became the more popular term after NASA climate scientist James Hansen used it in his 1988 testimony in the U.S. Senate. [34] Since the 2000s, climate change has ...

  5. Atmospheric carbon cycle - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_carbon_cycle

    After respiration, both carbon dioxide and methane are typically emitted into the atmosphere. Organic carbon is also released into the atmosphere during burning. [19] The residence time of carbon in the terrestrial biosphere varies and is dependent on a large number of factors. The uptake of carbon into the biosphere occurs on various time scales.

  6. Climate change feedbacks - Wikipedia

    en.wikipedia.org/wiki/Climate_change_feedbacks

    The Planck response is the additional thermal radiation objects emit as they get warmer. Whether Planck response is a climate change feedback depends on the context. In climate science the Planck response can be treated as an intrinsic part of warming that is separate from radiative feedbacks and carbon cycle feedbacks.

  7. Scientific consensus on climate change - Wikipedia

    en.wikipedia.org/wiki/Scientific_consensus_on...

    The majority of respondents had expected some warming to occur between 1970 and 2000, and described human emissions of carbon dioxide as the primary cause, but there was a disagreement on the extent, and a few had thought that an increase in volcanic activity would offset carbon dioxide emissions by elevating atmospheric sulfate concentrations ...

  8. Brian C. O'Neill - Wikipedia

    en.wikipedia.org/wiki/Brian_C._O'Neill

    Brian C. O'Neill (born 1965) is an American earth system scientist who studies the relationship between future societal development, emissions, and climate change impacts.O'Neill is known for interdisciplinary work on climate and human systems, in particular population and climate change.

  9. Carbon dioxide in Earth's atmosphere - Wikipedia

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

    Measurement of the GST is one of the many lines of evidence supporting the scientific consensus on climate change, which is that humans are causing warming of Earth's climate system. The global average and combined land and ocean surface temperature , show a warming of 1.09 °C (range: 0.95 to 1.20 °C) from 1850–1900 to 2011–2020, based on ...
