Dubai: A controversial film about global warming that stars former US vice-president Al Gore is set to debut in UAE cinemas this week.

An Inconvenient Truth, which calls for large-scale action in order to avert a global catastrophe, will air from Thursday.

The film has catapulted Gore back into the limelight across the world and has fuelled suggestions that he might challenge for the US presidency once again.

It is being shown in the UAE soon after the arrival in local shops of the accompanying book, also called An Inconvenient Truth, which reached the top of the New York Times bestseller list.

An Inconvenient Truth, directed by Davis Guggenheim, developed from a multimedia presentation about global warming that Gore has given across the world to raise awareness.

Gore, who was vice-president for eight years under Bill Clinton, talks about the risk of polar ice caps collapsing and leading to a rise in sea levels that could flood coastal areas.

In addition, the film warns that major ocean currents could change direction as a result of global warming - leading to huge changes in climatic conditions in areas such as northern Europe.

Scientists approve

Gore, 58, tells viewers that if the amount of carbon dioxide released into the atmosphere by cars, aircraft and other polluters is cut, and that if more trees are grown to absorb the greenhouse gas, there is a chance to help prevent a global disaster.

Scientists have generally given the film a good reception, saying it is well researched and on the whole ties in with accepted academic wisdom on the subject of climate change, although some commentators have complained of inaccuracies.

As well as discussing global warming, the film features clips of Al Gore at various stages of his life.

Gore, who many feel is the only person who can beat Senator Hillary Clinton in the race for the 2008 Democratic presidential nomination, even reflects in the movie on his defeat at the hands of George W. Bush in the presidential election of 2000.

An Inconvenient Truth is the third-highest grossing documentary ever in the United States, having achieved box office sales of more than $20 million (Dh73.5 million).
