Global Warming.

There are a lot of global problems around the world, but the most important and dangerous is global warming. The world cares about other problems while global warming is series and dangerous global problem.

Global warming is increasing in earth's temperature gradually, because of many factors of human-made. In science language global warming is concentrations of greenhouses gases lead to increase in carbon dioxide (CO2) in atmosphere, as we know warming increases with increasing of carbon dioxide.

I'm going to write in this article about this global problem and every side of it, causes, what this problem lead to and suggest some solutions.

What is global warming bcause of?

One of many factors that cause global warming is desertification. Desertification is destroying forest lands or grassland because of urbanization; in other ward it is a movement of sand over the forested lands to become desert-like.

Desertification is happening in many places around the world, like the rainforests in Brazil which face very big eliminated and destroyed by direct or indirect human involved. In numbers, 2.4 acres of rainforests destroyed every second; which means 78 million acres per year. This happens in many places around the world and effect in global climate by make it more worm.

Desertification cause global warming by increasing temperatures, because it lead to lower relative humidity, fewer clouds and as a result, reduced precipitation. If the area of desertification expand, the area of warming will expand as well to make it global warming.

What is global warming cause?

Why do we have to do something to avoid more changing in climate? As we know, the global warming has many negative effects in our lives and environment. For example, it causes a big melting in Antarctica because of heat, which also affects us and stronger tropical hurricanes and storms, and much more.

Some scientists had done some researches about the link between global warming and hurricane strength, but their researches faced with denial. In fact, they have a link together; because of that over heat make the temperatures increase up of the surface of the oceans. Gathering of warming seawater provide energy for storms or hurricanes, and more heat causes stronger storms and hurricanes. However, as some researches said that the climate change will not make a real effect in storms or hurricanes strength until 2050 or later.
