Vida Natural 8ª C

Global Worming mentions the increase to it of the average temperature of the oceans and air close to the surface of the Land that if has verified in the decades most recent and to the possibility of its continuation during the chain of the century. The phenomenon if manisfeta as a problem in the temperature on the populated areas of the Hemisphere North, between the Artic Circle and Trópico de Câncer. The maritime climate of the South Hemisphere is more steady; although the average increase of the sea also reaches it. The maritime climate depends on the temperature of the oceans in the tropics; e this is in balance with the speed of evaporation of the water, with solar radiation that reaches the Land and the Effect Greenhouse.

Consequences:
The Europe has been punished for waves of heat of up to 40 centigrade degrees, cyclones reaches Brazil (mainly the south and Southeastern coast), the number of deserts increases to each day, forts hurricanes cause deaths and destruction in some regions of the polar planet and calotas is melting (factor that to cause the advance of the oceans on littoral cities). What it can be provoking everything this? the scientists are unanimous in affirm that the Global Heating is related to all these events. - Increase of the level of the oceans: with the increase of the temperature in the world, it is in course the melting of calotas polar. When increasing the water level the oceans, can occur, future, the submersion of many littoral cities; - Growth and sprouting of deserts: the increase of the temperature provokes the death of some species of animals and vegetables, unbalancing some ecosystems. Added to the deforestation that comes occurring, mainly in forests of tropical countries (African Brazil, countries), the trend is to increase each time more the desert-like regions of the planet Land; - Hurricane Increase, tufões and cyclones: the increase of the temperature makes with that bigger evaporation of waters of the oceans occurs, pontecializando these climatic types of catástofres; - Waves of heat: regions of amenas temperatures have suffered with the whitewash waves, or. In the European summer, for example if it has verified onadas of heat, provoking even though aged deaths of and children.

Causes:
One of the causes of the Global Heating, is the devastação of the ozone layer that protects our planet against the solar rays, but what it is happening with it? This being devastada for the pollution in our planet, forest fires, pollution of the industry, garbage among others things. Since that the industrial revolution started, I broke it of 1750 the emissions of carbon dioxide had increased 31%, methane 151%, nitrogen oxide 17% and tropospheric ozone 36%



Solutions:
- To diminish the fósseis fuel use (gasoline, diesel, kerosene) and to increase the use of biocombustíveis (example: biodiesel) and etanol.
- The automobiles must be regulated constatemente to prevent the fuel burning of desregulada form. The obligator use of catalyser in exhaust pipes of automobiles, motions and trucks. - Installation of systems of control of emission of pollutant gases in the industries.
- To extend the generation of energy through clean sources and you renewed: aeolian, solar, nuclear and maremotriz hidrelétrica. To prevent to the maximum the generation of energy through thermoelectrial, that they use fósseis fuels.
- That Always possible, to leave the car in house and to use collective system of tranporte (bus, subway, trains) or bicycle.
- To collaborate for the system of selective collection of garbage and recycling.
- Recovery of the gas methane in the sanitary aterros.
