The main greenhouse gas. What is greenhouse gas?

Production human activity entails harmful effects on the atmosphere. This factor has already become a banality and pay attention to it is that experts in the environmental field. Meanwhile, harmful emissions pose increasingly acute problems to the organizations, dealing with global climate change. The list of the most acute problems at the conferences on the environment are regularly featured greenhouse gas as one of the most dangerous factors of influence on the atmosphere and biota. The fact that gaseous compounds of this type are unable to pass the thermal radiation, which contributes to the heating of the atmosphere. There are several sources of such gases, among which biological phenomena. And now is more familiar with the composition of greenhouse mixes.

Water vapor as the main greenhouse gas

Gases of this type generate approximately 60% of the total volume of substances which creates the greenhouse effect. With the growth of temperature of the Earth increase evaporation, and the total concentration of water vapor in the atmosphere. At the same time will maintain the moisture level that contributes to the greenhouse effect. Natural essence, which has a greenhouse gas in the form of steam, undoubtedly, has a positive side in the natural regulation of atmospheric composition. But there are negative consequences of this process. The fact that against the background of increasing moisture and increasing cloud mass, which reflects the direct rays of the sun. The result holds already antipenkova effect, which decreases the intensity of thermal radiation and, consequently, warming the atmosphere.

Carbon dioxide

Among the main emission sources of this type can be called volcanic eruptions, human activities and processes occurring in the biosphere. The anthropogenic sources include combustion of fuels and biomass, industrial processes and other factors leading to the formation of carbon dioxide. This is the greenhouse gas that actively participates in the processes of biocoenosis. It is also the most durable from the point of view of stay in the atmosphere. According to some information, the further accumulation of carbon dioxide in the atmospheric layers is limited by the risk of consequences not only for the equilibrium in the biosphere, but also for the existence of human civilization as a whole. Such views are the primary motivation for development of measures to counteract the greenhouse effect.

Methane

This gas remains in the atmosphere about 10 years. Before, it was believed that the effect of methane on the stimulation of the greenhouse effect 25 times more than carbon dioxide. But the latest research gave an even more pessimistic results – was that the potential impact of this gas have been underestimated. However, the situation softens a short period, during which the atmosphere keeps the methane. Greenhouse gas of this type is a result of anthropogenic activities. This can be rice, digestive fermentation, the reduction of forests, etc. According to some studies, the intensive growth of the methane concentration took place in the first Millennium of our era. Such phenomena were associated with the expansion of pastoralism and agricultural production, as well as burning forests. In the next century the concentration of methane decreased, although in our days bucking the trend.

Ozone

As part of the greenhouse gaseous compounds are not only dangerous from the point of view of climate change components, but also a beneficial part. These include the ozone that protects the Earth from ultraviolet light. However, not everything is clear. Scientists divide the gas into two categories – tropospheric and stratospheric. As to the first, it can be dangerous due to its toxicity. Along with this the high content of tropospheric elements contributes to the growth of the greenhouse effect. At the same stratospheric layer acts as the main protection to the effects of harmful radiation. In regions where greenhouse gas of this type has a high concentration, watching a strong impact on vegetation, which are manifested in inhibition of photosynthetic capacity.

Counteract the greenhouse effect

There are several areas in which work is under way on methods of containment of the process. Among the key measures highlighted the use of instruments of regulation of interaction of drives and sinks of greenhouse gases. In particular, environmental agreements at the local level contribute to the active development of forestry. Here it is worth noting the activities on afforestation, which in the future will minimize the greenhouse effect. Gas emitted into the atmosphere from industries, are also amenable to the reduction in many industries. This introduced measures to limit emissions in transport, industrial sectors, power stations, etc. to this end, developed alternative methods of fuel reprocessing and system gasolineria. For example, in recent years actively promoted the systemrecovery, allowing enterprises to optimize the processes of removal of their waste.

Conclusion

In the formation of the greenhouse effect human activity plays the most important role. It shows the share of gas volumes that are produced from anthropogenic sources. However, these emissions are the most dangerous for the atmosphere. Therefore, environmental organizations consider greenhouse gas as a factor in negative climate change. In the end, apply tools to contain the spread and accumulation of harmful substances that increase the risk of global warming. Moreover, the fight against harmful emissions is carried out in a variety of ways. This applies not only to factories and enterprises, but also products intended for individual use.
