For its importance, it must be five star (or 10 out of 10)!! .. And it should be titled 'Six Degrees WILL Change the World'.. for that for sure is exactly where we are heading!! It's critical... be sure and send the link to everyone you know.. (it also can be viewed on NatGeo & youtube.. bit.ly/1tC2LHt ) As for 'fear-mongering' ...we should ALL be, to the max terrified !! Once you've traveled to most every location cited in this film, and viewed first hand, and spoken with the local people severely impacted, you understand the threat is VERY REAL, and truly deadly serious. We have the distinct possibility of being just a generation (at most two) away from beginnings of a run-away 'sixth mass extinction'... which will include an ever increasing percentage of the overall human population.

I recently watch this movie on National Geographic Channel.I found that the information that was provided was very accurate but had an issue with the way some of the information was given. The film consistently changed from Centigrade (Celsius) to Fahrenheit and vice versa. This made the film very hard to comprehend as one had to be able to convert to either one of the temperature scales at a moments notice. It was had for me and I am a math major. It would have been better if the writers had stuck to one scale or the other.Seeing how just adding one degree Fahrenheit to the average temperature can change the climate is very alarming.This may not effect us currently but will effect future generations. Animal and plant life will change. Ocean levels will change. All will change over time.

Major spoiler here: we are having a dramatic impact on the climate, and the climate change will have a dramatic impact on us.Some years ago still, managing the interests of all sorts of industrial groups was causing censorship of key material. Not any more. This documentary is nicely done: scientific data, little computer imagery, no time fillers, less 100% US trivia, and no careful, tactful, industrially-correct comments. The documentary points the blame to those who deserve it: in the North for our individual excesses in energy consumption and materialism, in the South for out of control population growth, and everywhere for an economic and industrial model which is short sighted.6 degrees will basically endanger animal life, cause famine, war, and also the odd flooding and hurricane. Big spoiler, in fact this does not happen during the documentary, this will only happen to our kids.
