Carbon makes up only 0.08% of the combination of the lithosphere, hydrosphere, and atmosphere. Yet it is the twelfth most common element there. In the rock of the lithosphere, carbon commonly occurs as carbonate minerals containing calcium or magnesium. It is also found as fossil fuels in coal and petroleum and gas.
The carbon cycle was first described by Antoine Lavoisier and Joseph Priestley, and popularised by Humphry Davy. [5] The global carbon cycle is now usually divided into the following major reservoirs of carbon (also called carbon pools) interconnected by pathways of exchange: [6] Atmosphere; Terrestrial biosphere
Carbon is the fourth most abundant chemical element in the observable universe by mass after hydrogen, helium, and oxygen. Carbon is abundant in the Sun, stars, comets, and in the atmospheres of most planets. [52] Some meteorites contain microscopic diamonds that were formed when the Solar System was still a protoplanetary disk. [53]
Carbon-based photosynthesis life caused a rise in oxygen on Earth. This increase of oxygen helped plate tectonics form the first continents. [10] It is frequently assumed in astrobiology that if life exists elsewhere in the Universe, it will also be carbon-based. [11] [12] Critics, like Carl Sagan in 1973, refer to this assumption as carbon ...
The Lomagundi-Jatuli Carbon Isotope Excursion or Lomagundi-Jatuli Event (LJE) was a carbon isotope excursion that occurred in the Paleoproterozoic between 2.3-2.1 Ga, possessing the largest magnitude and longest duration of positive δ 13 C values found in marine carbonate rocks. [1] [2] The δ 13 C values range from +5 to + 30‰.

The world's first coal-fired power plant designed to capture and store carbon dioxide that it produces began operations in Spremberg, Germany. Built alongside the 1,600MW Schwarze Pumpe power plant in north Germany, the demonstration experiment will capture up to 100,000 tonnes of CO 2 a year, compress it and bury it 3,000m below the surface of ...
