Global warming

Introduction

Global warming is the increase of the Earth’s average temperature in the atmosphere and in the near surface air of the Earth, caused by human activities. Activities like burning harmful gases such as carbon dioxide (CO2). That results in the ice volumes melting which contributes to the rise in sea level.

Global warming is becoming a serious problem especially within the last few years because there are poor efforts to fight the change of climate especially by the large industrial countries such as the USA and China. The USA was the world’s largest producer of carbon dioxide in 2005 and China was the second. Those countries were the biggest producers of coal in 2005 which was the largest source of carbon dioxide emissions in this year.

My opinion for the movie “An Inconvenient Truth”

There were two strong factors in the movie that helped people to understand the danger and the importance of the global warming, emotional and informational factors. Regarding the emotional side, the movie used great music to attract people and let them get deep into it. Stories were also used in the movie to motivate people’s feeling toward problems and effects that are caused by the global warming. Regarding the informational side, the presenter in the movie gave some information and statistics to educate people about the consequences of the climate change and gave some solutions that they could help fight global warming. I think that the two sides in the movie were given perfectly by the presenter and I also think that the language in the movie was clear and understandable.

Causes

There are many causes for green house gas emissions which contribute to global warming. Many scientists believe that a number of human activities contribute the increasing greenhouse gases emissions such as carbon dioxide, methane, and nitrous oxide. Those gases play an important role in trapping heat in earth’s atmosphere and that process results in warming of the earth’s climate. One of the human activities is burning coal and fossil fuels which are called power plants. That power was the major source of carbon dioxide in 2005. From the consumption of coal, China and the US were the highest producers of carbon dioxide.

Effects

There are many effects for the global warming in our world and the most dangerous one is on ice. The increasing temperature leads to melting in the ice sheets and volumes which are located in the northen parts of the world. That will result in drowning many islands around the world because of the rise of sea levels as a result of melting ice sheets. Another disaster expected from rising sea levels is the disappearance of many coasts around the world. Melting of ice and snow will result in floods in some places around the world and that is considered as an effect of global warming which threatens lives in those areas. A further effect for global warming is changes in precipitation which will result in droughts in some parts of our world.
