An Inconvenient Truth, A movie on the topic of Global warming. Options

[Spartan]

I write this now to Inform You all that you should watch this movie..."An Inconvenient Truth".

This Movie Is all about Global warming effects on earth. The Prompter Is none other than Former American Presidential Candidate "Al Gore". He speaks about how The world is changing for the worse and how WE are contributing to the problem..He talks about Floods, Destruction of Rain forests, Melting of the Ice Caps, etc. He even goes on to talk about our car emissions and so forth. I urge you all to watch this movie Not only to inform yourselves of the problem but also to see what you can do to help reduce global warming.

Their is a survey in on a website "ClimateCrisis" which gives a rough estimate as to your current Contribution to the greenhouse effect. Mine a stunning 18.75...the average being 7.5..I was truly shocked by this movie and I hope that it will change your outlook on the subject as well. I urge that you go down the corner to your neighborhood blockbuster and Rent this movie. There were soo many shocking and disturbing Images and Graphs and Calculations from Leading scientists that it was simply and utterly shocking. I overuse the term when I use "shocking" but I mean it.

this movie is fascinatingly Interesting so if you have the time I recommend that you watch it.

Instead of complaining we are heating the Earth up you might want to consider that every 100,000 years or so the Earth WARMS up enough that we arent one big ice ball. This period generally last about 20,000 years. Guess what??? Yep you win the prize we are about 20,000 yrs into the current period of warm climate. I guess green house gases from the combustion engine were to blame at the begining of this current 20,000 year warm up.....

You obviously are referring to information that was circulating in 2005. These past two years have seen a dramatic increase in both CO2 and global temperature which have pushed way beyond any past historical highs. The British Antartic Survey released data in September from ice cores that dated back 800,000 years. At that time, the BBC quoted Glacial Chemist, Eric Wolff, one of the principal investigators as he reported the results, "My point would be that there's nothing in the ice core that gives us any cause for comfort. There's nothing that suggests that the Earth will take care of the increase in carbon dioxide. The ice core suggests that the increase in carbon dioxide will definitely give us a climate change that will be dangerous."

The previous data showed that CO2 and temperature fluctuated in consort. This is no longer the case. Since the 1970's atmospheric CO2 rose at an average rate of 1.5 ppm per year. Last year that spiked to 2.05 ppm and a series of similar jumps since 2001 has altered that steady growth to 2.1 ppm since 2001. These rates have raised CO2 levels 35% above pre-industrial levels.

Something fundamental is happening. This increase can't be blamed on pollution alone. It appears as if the earth's historical ability to absorb CO2 has been maxed out and now the earth can no longer cleanse the CO2 the way it once did. But, before we jump to conclusions, we'll have to await more data. We do know that melting permafrost has the potential to release HUGE amounts of trapped CO2 and this year's predicted El Nino could really help push CO2 levels to unheard of proportions. This is absolutely not a typical warming cycle.

These recent CO2 levels have jumped so dramatically, going well beyond any historical highs recorded in the past 800,000 years. The million dollar question is, how will this dramatic increase in CO2 affect the earth's temperature. One can only guess.
