http://ides2161-2012.blogspot.com.au/2012/03/video-inconvenient-truth.html
about: global warming-climate change, sustainability and the impacts on society.
time length: 1:36hrs
year: 2006
brief summary:
Former vice president Al_Gore shares his concerns of global warming in this documentary. Gore first became aware of the issues on global warming in the 1970s, and since leaving public office he has became a long-time environmental activist and a passionate advocate for changes in the laws and lifestyles that could help this crisis. An Inconvenient Truth shows Gore in a presesntation where he discusses the scientific facts behind global warming, explaining how it has already been affecting our environment/ecosystem. he also talks about the troubling consequences if the world's governments and citizens do not act soon, and shares what an individual can do to help preserve the Earth for us and our future generations. An Inconvenient Truth was directed by Davis_Guggenheim, a veteran documentary filmmaker who also has an extensive background in episodic television.
dot points of the video:
-less than 10 years time there will be an significant increase (off the charts)
-melting the glaciers, decrease the natural springwater that people rely on for drinking, which 40% of people rely on to get their water
-the relationship between Co2 concentrations and the temperature in the northern hemisphere, he looks at this through a chart where he states that in all the times of 65000 years co2 has never gone above 300 points per million except when you look at the temperature being increased (due to heat getting trapped in the atmosphere), the co2 today has increased dramatically and will continue to do so as the years go by. "in less than 50 years, co2 will rise-off the charts."
-as the temperature continues to increase, it plumets the thicknes of the ice caps, leading to extinction of some species or them being harmed by the bleaching of coral reefs. 
-Polar bears have even drowned due to the cause of the melting ice, having to swim for kms and not being able to rest on the ice blocks.
-Gore also talks about his life experiences --his son which changed his perspective on everything, saying what will we leave behind for our future generations? and "what we take for granted might not be here for our children"
-provides statistics and events around the world that has impacted greatly on the environment. for eg: Japan's record of typhoons, Brazil having their first hurricane --rewrites history books, hurricane Denise --oil leakage--> problematic to industries and the ecosystem.
-altering the seasonal climates eg: birds and caterpillars are hatched in the same time in spring but due to the climate change, where the temperature becomes warmer before spring actually hits, they hatch before the birds do and so baby chicks find it more difficult to survive.
-more insects survive, leading to more damaged crops  eg: the pine beatle -destroying pine trees--> decreasing resources to industries
-mosquitoes also expand in numbers and increasing diseases
-bringing in initiatives to decrease the amount of carbon pollutants through using more renewable resources and reducing the amount of water usage.
-Countries like China are producing higher mileage cars that meet the environmental standards.
-the people in the US are aiming to step on the band wagon as they are the largest contributor to carbon emissions
-Gore further discuss that we have done many damage to our Earth and we need to start immediately to preserve what we have left, work as a community to help make our environment a more livable place not just for us but for our future generations to come.
