Carbon dioxide in Earth's atmosphere
Carbon dioxide (CO2) is an important trace gas in Earth's atmosphere currently constituting about 0.04% (400 parts per million) of the atmosphere. Despite its relatively small concentration, CO2 is a potent greenhouse gas and plays a vital role in regulating Earth's surface temperature through radiative forcing and the greenhouse effect. Reconstructions show that concentrations of CO2 in the atmosphere have varied, ranging from as high as 7,000 parts per million during the Cambrian period about 500 million years ago to as low as 180 parts per million during the Quaternary glaciation of the last two million years.Carbon dioxide is an integral part of the carbon cycle, a biogeochemical cycle in which carbon is exchanged between the Earth's oceans, soil, rocks and biosphere. The present biosphere of Earth is dependent on atmospheric CO2 for its existence. Plants and other photoautotrophs use solar energy to synthesize carbohydrate from atmospheric carbon dioxide and water by photosynthesis. Carbohydrate derived from consumption of plants as food is the primary source of energy and carbon compounds in almost all other organisms.The current episode of global warming is attributed primarily to increasing industrial CO2 emissions into Earth's atmosphere. The global annual mean concentration of CO2 in the atmosphere has increased markedly since the Industrial Revolution, from 280 ppm to 400 ppm as of 2015. The present concentration is the highest in the past 800,000 years and likely the highest in the past 20 million years. The increase has been caused by anthropogenic sources, particularly the burning of fossil fuels and deforestation. The daily average concentration of atmospheric CO2 at Mauna Loa first exceeded 400 ppm on 10 May 2013. It is currently rising at a rate of approximately 2 ppm/year and accelerating. An estimated 30–40% of the CO2 released by humans into the atmosphere dissolves into oceans, rivers and lakes. which contributes to ocean acidification.
