  2. Deforestation and climate change - Wikipedia

    en.wikipedia.org/wiki/Deforestation_and_climate...

    The more trees that are removed equals larger effects of climate change which, in turn, results in the loss of more trees. [13] Forests cover 31% of the land area on Earth. Every year, 75,700 square kilometers (18.7 million acres) of the forest is lost. [14] There was a 12% increase in the loss of primary tropical forests from 2019 to 2020. [15]

  3. Atmospheric methane removal - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_methane_removal

    Methane has a limited atmospheric lifetime, about 10 years, due to substantial methane sinks. The primary methane sink is atmospheric oxidation, from hydroxyl radicals (~90% of the total sink) and chlorine radicals (0-5% of the total sink). The rest is consumed by methanotrophs and other methane-oxidizing bacteria and archaea in soils (~5%). [5]

  4. Carbon sink - Wikipedia

    en.wikipedia.org/wiki/Carbon_sink

    An important consideration in such efforts is that forests can turn from sinks to carbon sources. [25] [26] [27] In 2019 forests took up a third less carbon than they did in the 1990s, due to higher temperatures, droughts [28] and deforestation. The typical tropical forest may become a carbon source by the 2060s. [29]

  5. Atmospheric methane - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_methane

    Forest soils act as good sinks for atmospheric methane because soils are optimally moist for methanotroph activity, and the movement of gases between soil and atmosphere (soil diffusivity) is high. [73] With a lower water table, any methane in the soil has to make it past the methanotrophic bacteria before it can reach the atmosphere.

    Forests and other land ecosystems failed to curb climate change in 2023 as intense drought in the Amazon rainforest and record wildfires in Canada hampered their natural ability to absorb carbon ...

  7. Deforestation - Wikipedia

    en.wikipedia.org/wiki/Deforestation

    An important consideration in such efforts is that forests can turn from sinks to carbon sources. [163] [164] [165] In 2019 forests took up a third less carbon than they did in the 1990s, due to higher temperatures, droughts [166] and deforestation. The typical tropical forest may become a carbon source by the 2060s. [167]

  8. Greenhouse gas emissions from wetlands - Wikipedia

    en.wikipedia.org/wiki/Greenhouse_gas_emissions...

    Some wetlands are a significant source of methane emissions [6] [7] and some are also emitters of nitrous oxide. [8] [9] Nitrous oxide is a greenhouse gas with a global warming potential 300 times that of carbon dioxide and is the dominant ozone-depleting substance emitted in the 21st century. [10] Wetlands can also act as a sink for greenhouse ...

    en.wikipedia.org/wiki/Carbon_sequestration

    An important consideration in such efforts is that forests can turn from sinks to carbon sources. [24] [25] [26] In 2019 forests took up a third less carbon than they did in the 1990s, due to higher temperatures, droughts [27] and deforestation. The typical tropical forest may become a carbon source by the 2060s. [28]
