Climate Changes and Global Warming

In recent years, climate changes and global warming have become very important meteorological issues. There are several theories about the causes of this phenomenon, some of which emphasize the effect of greenhouse gases and others consider processes such as volcanic and geothermal activity as well as solar activity. Since the beginning of the industrial age, the world's population has grown from a few hundred million to several billion. The pattern of human life two hundred years ago changed to the pattern of luxurious and consuming human life of the twenty-first century. The phenomenon of global warming and climate change has occurred primarily due to the consumption of fossil energy sources (coal, oil, and gas) and secondly, the conversion of forests and green spaces into agricultural lands and urban settlements. In the meantime, industrial man, with every step increased the amount of greenhouse gases in the atmosphere. Climate change, and in particular global warming, poses many problems for human, including deaths from storms, floods, earthquakes, and tsunamis, landslides, heat waves, droughts, and water-related diseases. Developing countries suffer the most, despite less involvement in climate change. So far, science has played an effective role in identifying the causes, nature and consequences of global warming, but the role of some countries, especially developing countries, in global research on this issue has not been significant. This phenomenon and its negative effects on fossil fuels can be aware by public awareness, optimal use of fuel and energy, increasing the level of green space and preventing deforestation, recycling materials and using renewable energy alternatives to fossil fuels. Of course, the issue of climate change is a problem with many dimensions, and so far environmental issue has been attended but surely has different causes and effects. Today, the health of the planet is one of the most important topics to be studied and researched. To understand this issue, it is necessary to obtain the new knowledge in order to find ways of sustainable development via interdisciplinary sciences and cooperation of scientists at the national and international level. Therefore, in order to deal with this phenomenon, each country must present its scientific and economic program in line with global models in order to find ways of sustainable development and economy based on environmental development. Controlling climate change requires the scientific and executive synergy of all nations of the world, which must be given serious consideration by governments.
