GLOBAL WARMING IS A SERIOUS THING .

Global warming is an expression often found in texts and articles on current affairs or environment, the term refers to the temperature increase that has affected Brazil and the world. The occurrence of this fact is related to several factors that together cause a "domino effect", some being directly or indirectly linked to this phenomenon can endangered by life on Earth.Main factors:- Burning of fossil fuels: responsible for the emission of CO2 and other gases that contribute to the greenhouse effect.- Fires: In addition to reducing the extent of existing green area are still capable of releasing a high rate of atmospheric carbon dioxide (CO2)- Deforestation: green areas also decrease, causing the absorption of CO2 by plants decreases, causing an accumulation of gas in the atmosphere (especially in large urban centers).- Agriculture: Increasing agricultural production is a major reason for the fires and / or clearing of green areas, both often made indiscriminately.- Expansion technology: With easy access to product luxury once considered in the case of the car (the main source of CO2), for example, the technology has become a rogue for the environment.These and many other causes may also be related to the occurrence of global warming, but all lead to the same result: the overheating of the planet. Heating can bring sudden changes in living conditions on the planet, especially in relation to humans. Examples we can point to some consequences such as:- Melting glaciers.- Commitment to the water supply in certain areas.- Reduction in agriculture- Increased hunger and poverty- Deaths from malnutrition- Increased incidence of diseases like dengue and malaria, leading to increase in the number of deaths.- Disappearance of nations- Increase in sea level- Increased occurrence of natural phenomena (storms, tornadoes, earthquakes)- Disappearance of diverse forms of life- Transformation of green areas (such as forests) in the cerrado, some cases even resulting in the emergence of new deserts.- Possible increase erosion in coastal cities (due to increased sea level).- Extinction of territories and nations, such as islands and coastal cities.The main evidence of this phenomenon are the temperature measurements that have been obtained and evaluated for years, where the largest increases occurred in the periods 1910 to 1945 and from 1976 to 2000, although the warming has not been globally uniform. You can also refer to events observed frequently, as the remarkable increase in rainfall and natural phenomena such as tornadoes and earthquakes in areas where before there were common.
