I finally got around to seeing Al Gore's "An Inconvenient Truth" and recommend it highly. Even though it has long seemed to me obvious that our carbon emissions had to be having an impact on the world's atmosphere, I was surprised and pretty horrified by the weight of evidence the former vice president and president elect has built up.
Certainly, Gore has focused attention on this issue like no one else and the move underway toward alternative fuels, for example, is bound to gain even more momentum.
Gore quickly defines global warming - the buildup of carbon dioxide in the atmosphere that prevents the escape of reflected sunlight .
He then demonstrates through a series of charts how the modern era is burdened by a global population of about 6 billion compared with 2 billion when he was born; and how the burning of fossil fuels that started in earnest with the coal-fired factories of the industrial revolution in the 19th Century has caused the levels of carbon dioxide in the atmosphere to literally go off a chart that traces the data over 650,000 years through ice cores from Antartica!
He then points out evidence of a changing environment, including the number of 'record' hot years, the increase in major storms including Hurricane Katrina, the rapid retreat of the world's glaciers and the ongoing meltdown in the Arctic.
The evidence is overwhelming and it's astonishing that there is still a cadre of drivelers who continue to belittle the entire concept.
The documentary, which won an Oscar, is basically a lecture which he admits he has given "over 1,000 times." Well, practice makes perfect and the presentation is extremely tight and focused.
He ends it by pointing out that the technology exists to avert disaster; what we need is the political will. The notion that the current administration of former fossil fuel executives has any interest in this is risible; hopefully, a changing of the guard in 2008 will include a renewed focus on this very serious and growing problem.
But there is always the possibility that by the fall of 2008, we will have already experienced a monumental catastrophe that will make Katrina seem like a picnic. For while the move is on to alternative fuels, consider that China is planning to build 500 new coal-fired power plants over the next decade, according to an NPR report this morning.
