In 2006, former Senator Al Gore created an Academy Award-winning documentary on global warming called "An Inconvenient Truth." The film won several awards, including the Oscar for best documentary, and the gory film later received a noble peace prize. The film addresses several different topics of great concern when it comes to global warming; such as permafrost, rising temperatures, species extinction, drought and fatigue, to name a few. Four authors in five different articles discussed the three topics of greenhouse gases, climate change and the causes of global warming. These authors are writer and academic Bill McKibben in “Think Again: Climate Change” and “How Close to Catastrophe”; New York Times writer William J. Broad in “From a Rapt audience, a call to cool the hype”; Kevin O'Brien, writer for the Cleveland Plain Dealer, in “Global Warming? I’m not going to lose any sleep over this”; and Alan Zarembo, editor at the Los Angeles Times, in “Game over on global warming? Although the articles explain different topics from each other, only one of them cold-bloodedly disagrees about the causes of global warming being human, they all agree that There will be impacts on the environment, and everyone thinks that greenhouse gases are one of them. of the main causes of global warming. First, all the articles discussed responsibility for rising global temperatures. The problem may be serious, but O'Brien says it's simply the media taking another topic of interest and spreading it disproportionately. He claims there is global warming, 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 they cannot do it, but no matter what we do, even going back to the stone age, global warming will continue to increase because the waste that we have accumulated can dissolve slowly. On the other hand, 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 condemn ourselves to an early grave. In "How Close to Catastrophe", where he explains his own thoughts, he explains that it is not only humans who are to blame, but also the citizens of the United States..
