The Earth and its Atmosphere

Did it adjust in the past when huge volcanoes erupted  

The slogan should be Please leave this planet as you would wish to find it . So a wise and proper use of chemistry is vital if we are going to do that.

If the Earth s surface was frozen (temperatures near 273 K), the half-life of organic bases would have been around a million years (except for the more labile cytosine). Thus Miller and Levi suggest that biogenesis models should be developed under the premise that the earth and its atmosphere were cold, rather than hot.

Humans are an essential feature of the environment and it is false logic to view them as opposing or draining benefits from the environment. Of the total volume of the Earth and its atmosphere, the space available for animal and plant life is an exceedingly small portion. This is essentially the aqueous top layer of the Earth s surface, although there is, of course, an interaction in the form of gases with the atmosphere above the surface. 

By measuring the spectral distribution of the upwelling infrared radiation emitted by the Earth and its atmosphere, spaceborne sensors can provide information on the vertical temperature profile and on the atmospheric abundance of radiatively active trace gases. When local thermodynamic equilibrium conditions apply, the radiance received by a detector with spectral response function y> over frequency interval Av and viewing vertically downwards is given by (see Eq. 4.69a)... 

Fascinating as it is, carbon-14 has no further place in our story. It is the other main isotope of carbon, carbon-13, that concerns us here. Unlike carbon-14, carbon-13 has a stable nucleus and does not decay. In this respect, it is similar to carbon-12. The total amount of carbon-13 in the Earth and its atmosphere is therefore constant (1.11 per cent of the... 

The region of the Earth and its atmosphere in which living things are found is known as the biosphere. The biosphere is made up of distinct areas called ecosystems, each of which has its own characteristic climate, soils, and communities of plants and animals. 

The total infrared radiation emitted by the Earth and its atmosphere in the temperature range of approximately 200-300K. Because the Earth is nearly a perfect radiator, the radiation from its surface varies as the fourth power of the surface s absolute temperature. Terrestrial radiation provides a major part of the potential energy changes necessary to drive the atmospheric wind system and is responsible for maintaining the surface air temperature within limits for livability, thermocline... 

The energy produced by human activity cannot alter global climate directly because it represents only 1/10,000 of the total energy (120 x 10 J) absorbed in 1 s by the earth and its atmosphere. On the other hand, human activity is able to alter global climate indirectly by interfering with natural flows of energy through... 

Releases of carbon dioxide, methane, and other chemicals warm the earth and its atmosphere via the well-known greenhouse effect. The following effects result ...
