causes
In geologic history of our planet, climate change had occurred several times with cold and warm periods lasting thousands of years that we call ice ages and interglacial period . The last ice age happened 10,000 years ago and is now the stage warming interglacial period. In terms of causes of climate change, we can see the progress that is so dynamic and changing Earth axial tilt, shift the earth's orbit around the sun, the position of continents and oceans, and especially the changes in atmospheric composition.
While the first cause is the cause of the planet, it eventually causes the enormous impact of people that we Call it heats the atmosphere or the kinh.Co effect profile is understandable: The average temperature of the earth's surface is determined by the balance between the solar energy absorbed and returned to the heat universe. When much of the heat trapped in the atmosphere, the earth's temperature will rise. Key contains more CO2 in the atmosphere will act as a glass keeps heat is contrary to the universe of the earth. Along with CO2 gas, there are some other gases are collectively called greenhouse gases such as NOx, CH4, CFC. With the strong growth of industrial production and the use of fossil fuels (oil, coal, ..), the study by the researchers showed that global temperatures will rise between 1, 4 ° C between 1990 and 2100 to 5,8oC and so would entail the risk of deepening in the quality of human life. The Climate Change (CC) ongoing globalization increasingly serious. The most obvious indication that the warming of the earth, as the ice melts, rising sea levels; is the unusual weather, storms, floods, tsunamis, earthquakes, drought and prolonged cold ... leading to food shortages, food and mass appearance of disease in humans, livestock and poultry ...
