Scientists are reporting that the absolute limit which may create irreversible changes is the increase in average temperature by 2 ° C. This phenomenon at these rates is natural and is responsible for maintaining proper temperature on Earth.
Located in the atmosphere Earth’s water vapor and gases, eg. carbon dioxide, absorb heat emitted from the Earth and human OPERATIONS causes gases to escape into the atmosphere (eg. CFC) which INCREASES the greenhouse effect.
The climate on Earth depends on many factors over which man always has an impact. This does not change the activity of the sun and other natural factors, but increased Anthropopressure – (typically human activities (both planned and random) having an impact on the natural environment) is particularly dangerous from the point of view of further development of socio-economic growth.
Between 1970 and 2004. Emissions increased by 70%, which resulted in significant changes to the climate, Every year, the global CO2 emissions rising by 4.5%.
Carbon dioxide comes in particular the operation of fossil fuels, ie. Dioxide, coal, lignite, oil and gas.According to International Energy Agency of 30 May 2011.
The highest ever reached level was 30.6 gigatonnes.
The most visible manifestation of global warming is melting glaciers, which will raise ocean levels. It is estimated that every year Arctic ice area decreased by 35 thousand km and the overall level of water increases by 2-3 mm yearly. In the past 25 years the surface of Arctic glaciers has shrunk by area equal to the size of France, Germany and two-thirds of Poland.
By the end of the current century, sea levels will rise by as much as 1-1.5 m. The threat is so serious that the overall degree of ice in Greenland is raising sea levels by 7 meters, and for Antarctica 70 meters.
It is estimated that glaciers hold above 75% of the world’s freshwater resources. With rivers flowing from these glaciers draws water to more than 2.5 billion people, so the rise of water levels will have negative consequences for the local population if not the World.
Elimination and degradation of forests affected by the following factors: migratory agriculture Tungsten, logging, development of infrastructure, expansion of plantations, fields and pastures, and the phenomenon of urbanization.
Illegal logging also favors corruption of officials contributing to the greater poverty of local communities, which pushes them in the direction in overuse of their natural resources.
Contributing to deforestation are large corporations. eg, Western companies, which buy palm oil coming from deforested areas of Indonesian, Wasteful deforestation promotes the growth of GDP of Indonesia, but at the expense of vast area of forest, disappearing habitats and peat-lands. Deforestation leads to social conflicts and adverse affects on the lives of indigenous peoples forcing them to migrate to cities in order to find suitable living conditions.
According to researchers, at the current rate of deforestation, 2/3 species of animals living on Earth will disappear by the end of the twenty-first century.
Please keep in mind that the extinction of one species disturbs life cycle of another, and this in turn destabilizes the entire ecosystem.
Destroying biodiversity is irreparable loss for all mankind.
