Carbon dioxide in Earth's atmosphere
Carbon dioxide concentrations have varied widely over the Earth's 4.54 billion year history. It is believed to have been present in Earth's first atmosphere, shortly after Earth's formation.
Carbon dioxide
The carbon dioxide molecule is linear and centrosymmetric. The carbon–oxygen bond length is 116.3 pm, noticeably shorter than the bond length of a C–O single bond and even shorter than most other C–O multiply bonded functional groups. Since it is centrosymmetric, the molecule has no electrical dipole.
Carbon Dioxide Through the Geological Eras biocab.org
In prehistoric times, during the Permian, in the Palaeozoic Era, for example, the concentration of Carbon Dioxide dropped below 210 ppmV. Throughout the Permian Period plant and animal species diverged and diversified as never before.
About Carbon Dioxide
Carbon dioxide is a colourless, odorless gas. When inhaled at concentrations much higher than usual atmospheric levels, it can produce a sour taste in the mouth and a stinging sensation in the nose and throat.
Kohlenstoffdioxid in der Erdatmosphäre –
Im Gestein der Erde sind etwa 65.500 Gigatonnen Kohlenstoff gespeichert. In der Erdatmosphäre befinden sich dagegen bei 400 ppm nur 800 Gigatonnen Kohlenstoff, was 3000 Gigatonnen CO 2 entspricht – also nur etwa ein Prozent der Menge, die im Gestein enthalten ist.
Modelling the long term carbon cycle, atmospheric CO2, and ...
Over geological timescales, CO 2 levels are determined by the operation of the long term carbon cycle, and it is generally thought that changes in atmospheric CO 2 concentration have controlled variations in Earth's surface temperature over the Phanerozoic Eon.
Ordovician Period Paleoclimate | Britannica
Paleoclimate. Numerical climate models as well as carbon isotope measurements from preserved Ordovician soils suggest that atmospheric levels of carbon dioxide during the period were 14–16 times higher than today.
Palaeos Paleozoic: The Paleozoic Era
MAK. Paleozoic Climate. The Cambrian climate was probably moderate at first, becoming warmer over the course of the period, as the second greatest sustained sea level rise in the Phanerozoic got under way.
Phanerozoic History Plants Universe
At the time of the appearance of the first organisms about 3.8 billion years ago (see Figure 11 04a), there was no free oxygen, as there is now, but rather a "reducing atmosphere" composed of methane, carbon dioxide, ammonia, and hydrogen (see Figure 11 02a).
Palaeos : Archean : The Archean Eon
The Origin of the Continents. Rocks of the Lower Archean (in geology time is often referred to vertically, because younger rocks are deposited above older ones) are rare, and include the oldest known terrestrial rocks, about 3.8 billion years old.
