Global Main Problem

Global warming is the increase in the earth’s surface temperature; the world is facing this problem since the mid-twentieth century.[1] There are many natural causes which keep increase the earth temperature such as the greenhouse gasses, solar variation and volcanoes. In the other hand there are many causes that are human caused such as industrial output, fossil fuel (oil, gas and coal) and population; all of them are causing the increase in the carbon dioxide amount which is a very important element that has a hand in global warming.
Greenhouse gasses are increasing every year; heaters, coolers and ACs are the main source of those gasses. All countries warm or cold are part in this problem; countries with big population are more responsible because they consume more energy than others. They should work at finding alternatives to high numbers of cars, motorbikes and trains that powered by oil or coal.

We are already seeing the effect of global warming, in Europe the winter became shorter and warmer, and in Antarctica the ice begin to melt. Some countries like in south eastern Asia have faced a lot of floods, and I believe that the melting ice in south and north poles is the main cause of that.
