Impressive and surprising,
This review is from: An Inconvenient Truth [DVD] (DVD)
Whether you're a fan of Al Gore or not, he isn't really the issue here. He does a great job presenting the various forms of overwhelming evidence for global warming and mankind's link to it, but he doesn't do it in a political or spiteful way. He shows global temperature and atmospheric carbon patterns, and he shows that our last 20 years have been the highest by a longshot over the previous 600,000 years. Frankly, before seeing the film, I'd heard a lot of information about global warming being a myth, but this film dispels that notion with many independent pieces of evidence.
Even more importantly, it goes to show why we should care that global warming is occurring. As you may have seen in the trailer, if global warming continues at its current rate, the earth's coastlines will be flooded displacing tens of millions of people, it will increase the strength and frequency of hurricanes and tornadoes, it will irrevocably kill off many of the worlds glaciers, it will dry up lands interior to the coastline (like our heartland), and it will disrupt/kill species after species from polar bears to birds. These changes could occur in as short a time as ten to fifty years from NOW.
Lastly, he finishes with ways in which we can affect a change. It would be easy to see this film, get depressed about all the state of affairs, and throw up one's hands in despair, but the film offers us ways, big and small, to help reverse global warming's effects right now.
I urge you to see this film, you will not regret it.

My goodness, doesn't the truth offend?
Climate change has always been with us, but 'man made' is laughable! Since when did even a mildly warmer climate be disastrous for the earth or the UK for that matter? Answer, it hasn't. Naturally, you would have been the first to enjoy the so called 'ice age' - which was preceded by a much warmer age that had no negative consequences - but then it wasn't too long ago [1970's] that global cooling was the big threat - IT DID NOT HAPPEN LIKE THE CLEVER SCIENTIFIC PILLOCKS SAID IT WOULD - NEITHER WILL THE CURRENT GARBAGE THEY ARE CHURNING OUT. I know about the 'global cooling' scare because I was around when they were spouting that particular rubbish. Besides, Britain could do with some warmer weather, like it enjoyed centuries ago - without any negative results. Even Polar bears survived a warmer climate. The vikings enjoyed a then much warmer greenland. Study the history and stop being so gullible. And if those clever people are really that bothered about so called 'man 'made' whatever, then they should stop mouthing off and get back to pre industrial revolution times - but they ain't got the balls to do that. Why should people be made to believe any of this IPCC piffle? The qualifying expert credentials of many involved in the reports of that politically driven, state sponsored and corrupt organisation are at best questionable. And I have to say that the modus operandi regarding the construction of the said reports is the real sham here and a disgusting disgrace. There is also much hype about the computer models these people rely upon. A very good saying about computers is "Garbage in, garbage out". This is the position of the IPCC right now. What sickens me is the fact that there is a blanket refusal from all forms of 'man made' communication to allow anyone to hold a viewpoint that brings into question the warp and weft of spoon fed brainwashing tripe that people are daily being offered. Send the IPCC to the North East coast of England - that will give them a real taste of global cooling! No change here this time of year for decades. Maybe the IPCC can turn up the heat for us over here?
Warmer weather means less weather variability - not more! This is real weather science. But that is too uncatastrophic for the political puppet called the IPCC. I wonder how many will admit their misleading error in five or ten years time - probably only a handful of them....Just like the climate history of the past, the climate history of the future will one day prove them all wrong......

Eli - talk about blah, blah, blah - yawn - do you cut & paste the same text over and over again to any reviewer who doesn't share your (ill-informed, out of date, and parochial) views on the subject? I can categorically tell you I know more about this than you do from your rantings, but I don't feel the need to try to shout down people who have a different point of view. You've got your Global Warming Swindle, we all know the background to that. Its interesting you don't feel obliged to highlight the factual inaccuracies within that documentary and the crooked agenda of Martin Durkin. As I said in my other reply, just a case of a regional, middle aged nothing man who has no reason to care about the world as he never got the chance to make anything special of it himself. Nice legacy you're leaving your kids, btw.

Mr Hartley.. :) you are obviously not aware. Yesterday 11.12.2007 THREE UNIVERSITIES BACKED BY PEER REVIEWED SCIENCE, have once & for all quashed the GW debacle. THE SUN CAUSES IT. IT IS NATURAL. Of course, it won't be a big headline, because the Politicians would like a constant state of fear to keep us controlled. Meanwhile, rubbish like this film gets 5/5 from you and Amazon when it shouldn't - I think you are wasting time on here trying to prove to Eli otherwise don't you?

oh, ok then, if they say so, then its back to normal service. thank goodness for that, i can hop back in the toyota and continue tear-arsing around. sorry for the trouble, thanks for opening my eyes.

Having read your childish comments on other posts addressed to me, I can only say this.. you don't have to believe me Mr Hartley. Personally I couldn't give a damn. Be assured that people like you and the rest of the disinterested majority, are what's wrong with this planet. Not Co2.

awwwh.. was that the best you could do? lol
COMMON MISCONCEPTIONS ABOUT GLOBAL WARMING
MYTH 1: Global temperatures are rising at a rapid, unprecedented rate.
FACT: Accurate satellite, balloon and mountain top observations made over the last three decades have not shown any significant change in the long term rate of increase in global temperatures. Average ground station readings do show a mild warming of 0.6 to 0.8C over the last 100 years, which is well within the natural variations recorded in the last millennium. The ground station network suffers from an uneven distribution across the globe; the stations are preferentially located in growing urban and industrial areas ("heat islands"), which show substantially higher readings than adjacent rural areas ("land use effects").
There has been no catastrophic warming recorded.
MYTH 2: The "hockey stick" graph proves that the earth has experienced a steady, very gradual temperature decrease for 1000 years, then recently began a sudden increase.
FACT: Significant changes in climate have continually occurred throughout geologic time. For instance, the Medieval Warm Period, from around 1000 to1200 AD (when the Vikings farmed on Greenland) was followed by a period known as the Little Ice Age. Since the end of the 17th Century the "average global temperature" has been rising at the low steady rate mentioned above; although from 1940 - 1970 temperatures actually dropped, leading to a Global Cooling scare.
The "hockey stick", a poster boy of both the UN's IPCC and Canada's Environment Department, ignores historical recorded climatic swings, and has now also been proven to be flawed and statistically unreliable as well. It is a computer construct and a faulty one at that.
MYTH 3: Human produced carbon dioxide has increased over the last 100 years, adding to the Greenhouse effect, thus warming the earth.
FACT: Carbon dioxide levels have indeed changed for various reasons, human and otherwise, just as they have throughout geologic time. Since the beginning of the industrial revolution, the CO2 content of the atmosphere has increased. The RATE of growth during this period has also increased from about 0.2% per year to the present rate of about 0.4% per year,which growth rate has now been constant for the past 25 years. However, there is no proof that CO2 is the main driver of global warming. As measured in ice cores dated over many thousands of years, CO2 levels move up and down AFTER the temperature has done so, and thus are the RESULT OF, NOT THE CAUSE of warming. Geological field work in recent sediments confirms this causal relationship. There is solid evidence that, as temperatures move up and down naturally and cyclically through solar radiation, orbital and galactic influences, the warming surface layers of the earth's oceans expel more CO2 as a result.
MYTH 4: CO2 is the most common greenhouse gas.
FACT: Greenhouse gases form about 3 % of the atmosphere by volume. They consist of varying amounts, (about 97%) of water vapour and clouds, with the remainder being gases like CO2, CH4, Ozone and N2O, of which carbon dioxide is the largest amount. Hence, CO2 constitutes about 0.037% of the atmosphere. While the minor gases are more effective as "greenhouse agents" than water vapour and clouds, the latter are overwhelming the effect by their sheer volume and - in the end - are thought to be responsible for 60% of the "Greenhouse effect".
Those attributing climate change to CO2 rarely mention this important fact.
MYTH 5: Computer models verify that CO2 increases will cause significant global warming.
FACT: The computer models assume that CO2 is the primary climate driver, and that the Sun has an insignificant effect on climate. You cannot use the output of a model to verify or prove its initial assumption - that is circular reasoning and is illogical. Computer models can be made to roughly match the 20th century temperature rise by adjusting many input parameters and using strong positive feedbacks. They do not "prove" anything. Also, computer models predicting global warming are incapable of properly including the effects of the sun, cosmic rays and the clouds. The sun is a major cause of temperature variation on the earth surface as its received radiation changes all the time, This happens largely in cyclical fashion. The number and the lengths in time of sunspots can be correlated very closely with average temperatures on earth, e.g. the Little Ice Age and the Medieval Warm Period. Varying intensity of solar heat radiation affects the surface temperature of the oceans and the currents. Warmer ocean water expels gases, some of which are CO2. Solar radiation interferes with the cosmic ray flux, thus influencing the amount ionized nuclei which control cloud cover.
MYTH 6: The UN proved that man-made CO2 causes global warming.
FACT: In a 1996 report by the UN on global warming, two statements were deleted from the final draft. Here they are:
1) "None of the studies cited above has shown clear evidence that we can attribute the observed climate changes to increases in greenhouse gases."
2) "No study to date has positively attributed all or part of the climate change to man-made causes"
To the present day there is still no scientific proof that man-made CO2 causes significant global warming.
MYTH 7: CO2 is a pollutant.
FACT: This is absolutely not true. Nitrogen forms 80% of our atmosphere. We could not live in 100% nitrogen either. Carbon dioxide is no more a pollutant than nitrogen is. CO2 is essential to life on earth. It is necessary for plant growth since increased CO2 intake as a result of increased atmospheric concentration causes many trees and other plants to grow more vigorously. Unfortunately, the Canadian Government has included CO2 with a number of truly toxic and noxious substances listed by the Environmental Protection Act, only as their means to politically control it.
MYTH 8: Global warming will cause more storms and other weather extremes.
FACT: There is no scientific or statistical evidence whatsoever that supports such claims on a global scale. Regional variations may occur. Growing insurance and infrastructure repair costs, particularly in coastal areas, are sometimes claimed to be the result of increasing frequency and severity of storms, whereas in reality they are a function of increasing population density, escalating development value, and ever more media reporting.
MYTH 9: Receding glaciers and the calving of ice shelves are proof of global warming.
FACT: Glaciers have been receding and growing cyclically for hundreds of years. Recent glacier melting is a consequence of coming out of the very cool period of the Little Ice Age. Ice shelves have been breaking off for centuries. Scientists know of at least 33 periods of glaciers growing and then retreating. It's normal. Besides, glacier's health is dependent as much on precipitation as on temperature.
MYTH 10: The earth's poles are warming; polar ice caps are breaking up and melting and the sea level rising.
FACT: The earth is variable. The western Arctic may be getting somewhat warmer, due to unrelated cyclic events in the Pacific Ocean, but the Eastern Arctic and Greenland are getting colder. The small Palmer Peninsula of Antarctica is getting warmer, while the main Antarctic continent is actually cooling. Ice thicknesses are increasing both on Greenland and in Antarctica.
Sea level monitoring in the Pacific (Tuvalu) and Indian Oceans (Maldives) has shown no sign of any sea level rise.
Thank you. Now keep rolling around on the floor child.
