Global Warming Causes

The cause of global warming is what is called the “Greenhouse Effect.” In other words the increase in the man-made emission of greenhouse gases which are the cause of global warming. Greenhouse gases, for example carbon dioxide and methane act like a mirror in the atmosphere and reflect back to the earth a part of the heat radiation, which would otherwise be lost to space. The higher the concentration of green-house gases like carbon dioxide in the atmosphere, the more heat energy in being reflected back to the earth.

The emission of carbon dioxide into the environment mainly from burning of fossil fuel (oil, gas, petrol, kerosene, etc.) has increased dramatically over the past 50 years. Those are thought to be the known causes of global warming. However, researches is still being made in order to identify the main causes beyond this matter. Each of the mentioned causes needs to be studied in more details.

Specific cause of global warming

There are many causes of global warming and the major one is the CO2 that is produced from power plants. I chose this specific cause because in my opinion, this is the reason why a lot of CO2 is produced and proves a lot of facts. A long time ago, there weren't any power plants which explains why scientists have proven the difference of the amount of CO2 used nowadays than in the past. The burning of fossil fuels which are used for the purpose of electricity generation, means, the amount of CO2 produced these days outnumbers the amount that was used in the past. A lot of countries have power plants, so just imagine how much CO2 is being wasted. Every developing country does not use only one but many power plants and if this keeps going, then it will be a disaster. We cannot tell each country to stop using power plants because it is essential to have them. Instead, countries need to have a limit to the number of power plants to have so we can at least have a limit to the amount of CO2 each country produces.
