Global Warming Global warming is the gradual heating of Earth’s surface, ocean and atmosphere. As we all know, scientists have documented the rise in average temperatures of our World since 1800s and their studies are still going on. We usually hear about global warming together with climate change, because this two problems goes hand in hand just because they affect each other reciprocally. The major cause of these problems is the behaviour of the human being, industries, and multinationals who ignore the problem by continuing to produce more and more greenhouse gas emissions that lead to an increase in the Earth's temperature. According to the report of IPCC (Intergovernmental Panel on Climate Change) of 2007, the Earth’s temperature has increased by 0.18°C during the XX century and by 1.5°C above pre-industrial levels. They have also observed that global warming is not uniform on the globe and that the peak is present from medium to high latitudes to the north pole and that in the south pole is happening the opposite, that is, the cooling. The main causes of global warming are: intensive breeding, changes to the surface like deforestation, aerosol increase and above all the increase in the concentration of greenhouse gases in the atmosphere (carbon dioxide, methane, ozone and water vapour). Intensive breeding causes many consequences on climate warming, for example soil degradation, chemical pollution caused by pesticide and fertilizer, use of energy, water consumption and the high ammonia content in animal dehydration is one of the main causes of acid rain. Moreover the deforestation is a great problem because plants contribute to reduce the amount of carbon dioxide in the air, therefore forest destruction reduces the natural absorption capacity of greenhouse gases by accelerating the concentration process in the Earth's atmosphere and global overheating. Greenhouse gases come from all sorts of everyday activities, such as using electricity, heating our homes, and driving around town, in addition carbon dioxide is the most important greenhouse gas emitted by humans All of us could do something about it, for example we should use less our personal transport and use public ones to reduce emissions, take advantages of sunlight, for example studying and working with our desk near the windows. Since I live in Rome in my building the radiator is centralized and often when it's too hot at home we have to open the windows.
