During 2016 as a result of global warming and the impact of human activity there have been fires of great economic importance affecting different states of the United States and countries of the European Union and burned a large area more than of 250 thousand ha and more than 210 thousand ha respectively. Deforestation, forest fires and the impact of human activity contribute to increased levels of C02 and thus help to increase the temperature. Prospects fire also considered high for other countries such as Brazil and Australia where temperatures are rising.More heat on the planet indicates more activity natural forces of the Earth which gain energy to the extent that this is heated and endangers the balance of the planet and the sustainability of humanity.
In the past century large forest fires were reported in different countries, of which the most important occurred in Indonesia in the period 1997-1998 where 9.7 million hectares was burned, China in 1987 where 7.3 million hectares burned, Brazil in the Amazonas1998 which 3.9 million hectares were burned, followed in importance fires in Canada in 1989 and 1919 with 3.3 and 2.0 million hectares respectively and the United States in 1910 with 1.2 million ha that affected the states of Idaho, Montana and Washington.
During 2016 as a result of global warming and the impact of human activity there have been fires of great economic importance affecting different states of the United States and countries of the European Union and burned a large area of more than 250mil has and more than 210 thousand ha respectively as sources of information from different states and countries. In the United States the most affected areas are in the west and in the central region of the country. In Europe the areas affected by fires are mainly in Portugal, Spain, France, Italy and Greece, countries with characteristics of high temperatures and dry winds Portugal being the most damaged with more than 100 thousand hectares burned.
In 2012 it was burned in Spain 217 000 ha, currently there are about 45 thousand hectares burned has, increased the average monthly temperature of the summer months in more than 1 ° C, on September 6, 2016 maximum temperatures daily, were recorded above 44 degrees Celsius in the southern region of the country which has been declared a state of general alert for a high probability of fires.
Fire prospects for Brazil in 2016 are high as statistical data show that the fires increased by 65% for the same period for the year 2015. In Australia the average temperature increased by 0.9 ° C in relation to the period 1991-1992 so that the fire probability is high. Forest fires are caused by natural causes and accidental causes, but now the leading cause of fires is man, which causes great damage to the environment and meaning to the community.
In different regions of the world, there are coal mines that are burning naturally for hundreds of years. In Australia Mount Wingen, it is estimated that the coal mine has been burning for more than 5000 years. In Northwest Canada, Smoking Hills has been burning for hundreds of years. The coal mine in Germany near Dudweiler, has been burning for more than 300.años. In the United States a Pennsylvania coal mine is burning. In South Africa in the province of Mpumalanga there is a coal mine that is burning. Found in Zealand and China coal mine fire.
Global warming occurs primarily as a result of greenhouse gas emissions from the industrial revolution at the beginning of 1860 in global average global temperature was 13.6 degrees Celsius industrial stage and currently is around 14.7º C or it has already risen 1.1º C in 156 years. Since 2000 there have been 9 of 10 of the warmest years, so we are facing a great challenge and the planet warms further, increasing the risk of fire, measures taken today are still insufficient.
Forests are disappearing at an alarming rate to more than 4 million hectares / year, that at this rate of destruction them disappear in a short time due to many causes in which commercial felling of trees for furniture making and as matter premium for cardboard and paper production ranks first, followed in importance extensive livestock and crops with unsustainable agricultural practices. Also the construction of highways, roads, no harmonious development of mankind itself and mining contribute to deforestation and the disappearance of fauna and flora of the environment. These practices contribute to unsustainable changes that will accelerate global warming and climate change on the planet.
The elimination of forests changes the flow of moisture and air, resulting in changes of fluctuations in rainfall patterns and temperature increases that are equally harmful and happen immediately. Rainforests regulate climate. One of the ways in which they do is to remove water from the soil through the roots of trees, move through the stems and finally through the leaves. Millions of leaves and millions of trees have a very significant result of cooling, according to Nature Climate Change.
According to the FAO in 2011 the global forest area was 4033 million hectares, representing less than 0.6 hectare of forest / person: regions of lower forest area per capita is represented by China and the Caribbean and those of largest forest area per capita are in Oceania and South America, and it will decrease with the increase and development of the world population, deforestation and forest fires.
Deforestation and forest fires contribute to increased levels of C02 and thus help to increase the temperature. The impact of human activity considerably accelerates emissions of greenhouse gases into the atmosphere and global warming. More heat on the planet indicates more activity of natural forces of Earth, energy gain to the extent that this is heated and threatens the balance of the planet and the sustainability of humanity.
