2. Atmospheric carbon cycle - Wikipedia

   en.wikipedia.org/wiki/Atmospheric_carbon_cycle

   Although individual CO 2 molecules have a short residence time in the atmosphere, it takes an extremely long time for carbon dioxide levels to sink after sudden rises, due to e.g. volcanic eruptions or human activity [17] and among the many long-lasting greenhouse gases, it is the most important because it makes up the largest fraction of the ...

3. Carbon cycle - Wikipedia

   en.wikipedia.org/wiki/Carbon_cycle

   Carbon dioxide is also produced and released during the calcination of limestone for clinker production. [115] Clinker is an industrial precursor of cement . As of 2020 [update] , about 450 gigatons of fossil carbon have been extracted in total; an amount approaching the carbon contained in all of Earth's living terrestrial biomass. [ 114 ]

4. Life-cycle greenhouse gas emissions of energy sources

   en.wikipedia.org/wiki/Life-cycle_greenhouse_gas...

   The findings are presented in units of global warming potential per unit of electrical energy generated by that source. The scale uses the global warming potential unit, the carbon dioxide equivalent (CO 2 e), and the unit of electrical energy, the kilowatt hour (kWh). The goal of such assessments is to cover the full life of the source, from ...

5. Carbon-based life - Wikipedia

   en.wikipedia.org/wiki/Carbon-based_life

   Carbonic anhydrase needs a family of carbon base enzymes for the hydration of carbon dioxide and acid–base homeostasis, that regulates PH levels in life. [32] [33] In plant life, liquid water is needed for photosynthesis, the biological process plants use to convert light energy and carbon dioxide into chemical energy. [34]

6. Carbon dioxide in Earth's atmosphere - Wikipedia

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

   Even if human carbon dioxide emissions were to completely cease, atmospheric temperatures are not expected to decrease significantly in the short term. This is because the air temperature is determined by a balance between heating, due to greenhouse gases, and cooling due to heat transfer to the ocean.

7. 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.

8. Climate change - Wikipedia

   en.wikipedia.org/wiki/Climate_change

   Major increases in energy efficiency investment will be required to achieve climate goals, comparable to the level of investment in renewable energy. [309] Several COVID-19 related changes in energy use patterns, energy efficiency investments, and funding have made forecasts for this decade more difficult and uncertain. [310]

9. Carbon sequestration - Wikipedia

   en.wikipedia.org/wiki/Carbon_sequestration

   The sudden increase in carbon dioxide on the surface level will also temporarily decrease the pH of the seawater, impairing the growth of coral reefs. The production of carbonic acid through the dissolution of carbon dioxide in seawater hinders marine biogenic calcification and causes major disruptions to the oceanic food chain. [155]
