Cool cities
All over the world, there are Global warming’s effects . Scientists want to build green cities to reduce these effects and to find cool cities which are gave us good conditions to live. We must use modern technology to build cool cities. I will write about technology and how we can use it.

One method to reduce global warming’s emission is an operable roof that responds to the temperature - in the summer it will close up and reduce the sunlight that streams in, while in the winter it will open completely and use the desert air to heat the inside. Other methods shifts to a cleaner production, renewable energy, better water resource management, the reduction of solid waste and sewage treatment, the reuse and recycling of materials and improved public health practices.

In my opinion this is a good idea, because cool cities will reduce global warming emissions and we will live in healthy environment. For example, companies from Dubai and Abu Dhabi have teamed up with overseas partners to build a Dh6 billion (US$22bn) power station using hydrogen extracted from coal.

In conclusion, it is good to build cool cities in the nearest future. That will help us to control global warming emissions.

My opinion about an inconvenient truth movie

Now, I will tell you my opinion about an inconvenient video, is it political, scientific or art? I will tell you what government should do for this problem.

It is a scientific video, because Gore shoots himself in the foot by oversimplifying everything. He never gives any real science behind his theories. Rather, he says it’s too complicated and then throws a graph on screen and calls it gospel truth. The reality behind global warming is that (contrary to what Gore says), there is debate about it in the scientific world, particularly with people in the meteorology field. It is a political move, especially when the ending credits call for viewers to encourage everyone they know to see this movie and vote for environmentally friendly candidates. The government should solve this problem in the nearest years and limit the carbon dioxide quality which emit from many sources.

In conclusion, Al Gore gives us public idea about the global warming and results of this problem. So we must solve this problem by reducing carbon dioxide quality.

Summary of an Inconvenient Truth Movie

An Inconvenient Truth is an American documentary film about global warming, presented by former United States Vice President Al Gore. An Inconvenient Truth is the fourth-highest-grossing documentary film to date in the United States. The film's thesis is that global warming is real, potentially catastrophic, and human-caused. Gore presents specific data that supports the thesis which i will show it in this essay.

In the slide show Gore reviews the scientific opinion on climate change, discusses the politics and economics of global warming, and describes the consequences he believes global climate change will produce if the amount of human-generated greenhouse gases is not significantly reduced in the very near future. Gore discusses the possibility of the collapse of a major ice sheet in Greenland or in West Antarctica. In Greenland, glacier retreat has been observed in outlet glaciers, resulting in an increase of the ice flow rate and destabilization of the mass balance of the ice sheet that is their source. The climate of Antarctica is one of intense cold and great aridity. Most of the world's freshwater ice is contained in the great ice sheets that cover the continent of Antarctica. The retreat of glaciers, worldwide and rapid, affects the availability of fresh water for irrigation and domestic use, mountain recreation, animals and plants that depend on glacier-melt, and in the longer term, the level of the oceans.

In conclusion, the film shows that we faced big problem which is global warming. Al Gore advises us to find solution for this problem.
