greenhouse effect global warming: An Inconvenient Truth：global warming

An Inconvenient Truth is a 2006 documentary film, directed by Davis Guggenheim, about former United States Vice President Al Gore's campaign to educate citizens about global warming via a comprehensive slide show that, by his own estimate, he has given more than a thousand times.Since the documentary's release, An Inconvenient Truth has been credited for raising international public awareness of climate change and reenergizing the environmental movement.

Throughout the movie, Gore discusses the scientific opinion on climate change, as well as the present and future effects of global warming and stresses that climate change "is really not a political issue, so much as a moral one,"describing 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 also presents Antarctic ice coring data showing CO2 levels higher now than in the past 650,000 years.
