The topic global warming is an important issue nowadays. Global warming has two words that has summaries dangers that face humanity. Warming happens because of the effects of the gases that emit from cars and factories. These gases are full of smog and chemicals. However, these gases rise into the sky they make an umbrella around the earth. These gases prevent the rays of the sun to go into the earth. The rays stopped the heat of the earth to escape into the space. Therefore, glaciers are melting, sea levels are rising and wildlife is destroying.
It is clear that human beings are causing this catastrophe. Scientists believe that greenhouse gases are higher now than the last 650,000 years. As the earth spins each day, the new heat picks up moisture overseas and oceans. This moisture changes the climate that all living things have come to rely on. The face of the earth as we know as coasts, forests, farms and Snow Mountains may disappear totally. The more greenhouse gases are in the atmosphere, the more heat people feel. These gases are trapped in the atmosphere faster than it is expected to happen.
A scientist in the past has warned humanity against greenhouse gases but deaf ears met his warnings until recently. The average temperature of the earth stay constant until recently. The burning of fossil fuels enhance the greenhouse effect and warming the earth. Scientists use climate change instead of global warming. This is because the heat changes the weather all over the world. As a result, the climate changes differently in many places. The stability has allowed human civilization to develop so what will happen in the future people may not know. The heat increases rapidly since the industrial revolution. The change in weather take place over thousands of years but nowadays it happens over a short time.
The questions is; should we all be concerned? The answer must surely be yes. As humans cannot live on other planets so everyone should be concerned about this difficult problem. Everyone has a rule to do. Although our rule as individual is small, it is very important for the future of all human beings. Imagine getting up one day and finding that Green Land has disappeared or finding Antarctica melting what will happen at that time? Every place on the earth will be covered with water. Humans would not find a place to live on .So the rule of everyone is important.
