In 2006, former Senator Al Gore created an academic award-winning documentary on global warming titled "An Inconvenient Truth." The film earned numerous awards including an Academy Award for Best Documentary Feature, and Gore later received a Noble Peace Prize. The film discussed several topics of great concern regarding global warming; such as permafrost, rising temperatures, species extinction, drought and fatigue, to name a few. Four writers in five different articles discussed the three topics of greenhouse gases, climate change and the causes of global warming. These writers are writer and scholar Bill McKibben in “Think Again: Climate Change” and “How Close to catastrophe”; William J. Broad, writer for the New York Times in “From a Rapt audience, a call to cool the hype”; writer for the Cleveland Plain Dealer, Kevin O'Brien, in “Global Warming? I won't lose sleep over it”; and Alan Zarembo, editor of the Los Angeles Times, in “Game over on global warming?” Although the articles explain different topics from each other, only one of them bloodily disagrees about the causes of global warming for humans, they all agree that there will be impacts on the environment and everyone believes that greenhouse gases are one of them. of the primary causes of global warming. First, all the articles argued about who was to blame for the planet's rising temperatures. The issue may be serious, but O'Brien says it's simply the media using another topic of interest and blowing it out of proportion. He claims that global warming exists, but the statistics provided are constantly changing, so the blame game can't always point the finger at humans. Zarambo explained that humans are the cause of global warming but we cannot, no matter what we do, even return to the stone age, that global warming will continue to increase because the waste we have accumulated can slowly dissolve. On the opposite front, McKibben in “Think Again: Climate Change” explains that humans are to blame because the planet is already struggling to stay alive and all the excess heat we generate from CO2 and other waste, we are condemning ourselves to an early grave. In "How Close to catastrophe", where he explains his thoughts, he explains that it is not only the fault of human beings, but the citizens of the United States..
