An Inconvenient Truth


An Inconvenient Truth shows Al Gore and his travels in support of his thinking to educate the public about the severity of the climate changes. The film closely follows a Keynote presentation (dubbed "the slide show") that Gore presented throughout the people. It intersperses Gore's collection of data and predictions regarding climate change and its potential for disaster with Gore's life story about his sister who died because of lung cancer. In the slide show, Gore shows the scientific realities of climate changes, talks about the economics and politics that are connected with global warming, and describes the results he believes global climate change will produce if the amount of human-generated greenhouse gases is not dramatically reduced in the very near future. A main point of the film is his example of the annual temperature and CO2 levels for the last 650,000 years in Antarctic ice core samples.

I think that the movie is very useful. There are many excellent figures and information, and it talks about the realities of global warming. The solution is in our hands, as is well known and the solution is not to pollute the environment. The major industrial countries have to consider this matter well and see this movie to see the truth and what’s happening in the world.

global warming


The global warming is one of the important issues nowadays. Global warming means that the temperature of the earth is increasing. One of the main reasons of temperature increase is the greenhouse gases. Before the twentieth century there was no increase in temperature, but in the middle of the twentieth century the temperature began to increase because of gases from the factories and cars. It is expected that the temperature over the next fifty or one hundred years will increase; the earth may be hotter than millions of years before. That means the global warming will affect the plants, weather, animals and humans, so why are we cutting down forests? Burning fuels? Although we know this is bad for our planet we still do the same thing. The results of global warming are sea levels are increasing and cities along the coast may be flooded. High temperatures may cause forests to die and food crops to fail.
