Global Warming

Global Warming

Global Warming is the gradual increase in temperature on the Earth's surface and in the atmosphere, causing the global temperature to rise. When the sun's radiation (short wave radiation) reaches the Earth's surface, some of it is absorbed by the Earth and some is converted into heat radiation (long wave radiation) or infrared radiation. These heat waves are absorbed by gases in the atmosphere such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), providing a moderate level of heat for humans, animals, and plants to survive. These gases warm the Earth and act as a greenhouse, so they are called Greenhouse Gases (GHGs).

However, since the advent of the industrial era, the use of fossil fuels such as coal, gasoline, diesel, and natural gas has increased year by year due to the growth of factories and motor vehicles, which has led to an increase in the amount of greenhouse gases, including CO2, in the atmosphere. In this way, the ability to absorb heat from the atmosphere and re-radiate it back to the ground has increased, increasing the temperature of the earth. It is said that the earth's temperature is now 1 degree Fahrenheit (0.5 degrees Celsius) warmer than it was 140 years ago.

Climate change is caused by global warming, and global warming is also caused by the increase in greenhouse gas emissions. Climate change is a major challenge facing humanity today. The Fourth Assessment Report of the IPCC (Intergovernmental Panel on Climate Change) states that climate change poses a serious threat to economic growth, sustainable development and the survival of all living things. Furthermore, if greenhouse gas emissions continue at current rates and are allowed to double to pre-industrial levels, the world will experience an average temperature increase of 3 degrees Celsius this century. This will have adverse consequences, including rising sea levels, shifting cropping seasons, and increasing the frequency and intensity of extreme weather events such as storms, floods and droughts. Therefore, stabilizing the concentration of harmful greenhouse gases in the atmosphere is a shared responsibility of all humanity.
