Manufactured controversyA manufactured controversy (sometimes shortened to manufactroversy) is a contrived disagreement, typically motivated by profit or ideology, designed to create public confusion concerning an issue about which there is no substantial academic dispute. This concept has also been referred to as manufactured uncertainty. Manufacturing controversy has been a tactic used by ideological and corporate groups to "neutralize the influence of academic scientists" in public policy debates.
Michael CrichtonJohn Michael Crichton (ˈkraɪtən; October 23, 1942 – November 4, 2008) was an American writer and filmmaker. His books have sold over 200 million copies worldwide, and over a dozen have been adapted into films. His literary works heavily feature technology and are usually within the science fiction, techno-thriller, and medical fiction genres. Crichton’s novels often explore human technological advancement and attempted dominance over nature, both with frequently catastrophic results; many of his works are cautionary tales, especially regarding themes of biotechnology.
Global coolingGlobal cooling was a conjecture, especially during the 1970s, of imminent cooling of the Earth culminating in a period of extensive glaciation, due to the cooling effects of aerosols or orbital forcing. Some press reports in the 1970s speculated about continued cooling; these did not accurately reflect the scientific literature of the time, which was generally more concerned with warming from an enhanced greenhouse effect. In the mid 1970s, the limited temperature series available suggested that the temperature had decreased for several decades up to then.
Temperature record of the last 2,000 yearsThe temperature record of the last 2,000 years is reconstructed using data from climate proxy records in conjunction with the modern instrumental temperature record which only covers the last 170 years at a global scale. Large-scale reconstructions covering part or all of the 1st millennium and 2nd millennium have shown that recent temperatures are exceptional: the Intergovernmental Panel on Climate Change Fourth Assessment Report of 2007 concluded that "Average Northern Hemisphere temperatures during the second half of the 20th century were very likely higher than during any other 50-year period in the last 500 years and likely the highest in at least the past 1,300 years.
An Inconvenient TruthAn Inconvenient Truth is a 2006 American concert film/documentary film directed by Davis Guggenheim about former United States Vice President Al Gore's campaign to educate people about global warming. The film features a slide show that, by Gore's own estimate, he has presented over 1,000 times to audiences worldwide. The idea to document Gore's efforts came from producer Laurie David, who saw his presentation at a town hall meeting on global warming, which coincided with the opening of The Day After Tomorrow.
Individual action on climate changeIndividual action on climate change can include personal choices in many areas, such as diet, travel, household energy use, consumption of goods and services, and family size. Individuals can also engage in local and political advocacy around issues of climate change. People who wish to reduce their carbon footprint (particularly those in high income countries with high consumption lifestyles), can take "high-impact" actions, such as avoiding frequent flying and petrol fuelled cars, eating mainly a plant-based diet, having fewer children, using clothes and electrical products for longer, and electrifying homes.
