The Causes

Global Warming Causes

The global warming phenomenon has many causes. These causes are divided into two groups. These groups are mainly natural causes and man-made.

Natural Causes

Firstly, let’s start with natural causes. There are several numbers of causes under this tag. One important cause is the release of methane gas, which is one of the greenhouse gases, from arctic tundra and wetlands. Another natural cause is the earth’s climate change cycle which usually lasts for 40,000 years.

Man-made Causes

There are also some causes for the global warming because of human activities. The first important one which has many shapes and sizes is pollution. Cars, trains, factories and all things which give off greenhouse gases. When you burn the fossil fuel CO2 (carbon dioxide) is given off. This is one of the most effective greenhouse gases, which keeps heat and carbon emissions in our atmosphere and does not allow them to go out to space.

Another man-made cause is the huge increase in world population. The more people we have the more food, we need the more space we need….etc. That means there is more fossil fuel going to be burnt which means more emissions of greenhouse gases. Moreover, the increase in population demolished many trees which help to convert CO2 to O2, which means we are going to have more greenhouse gases.
