Thank you to those who have replied the original link didn’t work. The below one at NationaGeographic.com <http://nationageographic.com/> does!
I recommend watching Leonardo Di Caprio’s Before the Flood, a moving documentary film about climate change <https://en.wikipedia.org/wiki/Climate_change> that debuted last Sunday on the National Geographic Channel <https://en.wikipedia.org/wiki/National_Geographic_Channel>. As part of National Geographic's commitment to covering climate change, the documentary has been made widely available and free of charge on various platforms. Before The Flood received positive reviews from critics, currently holding an 8.6 out of 10 rating on IMDB based on 2744 reviews as of October 31, 2016. It was described as 'surprisingly moving' in W (magazine) <https://en.wikipedia.org/wiki/W_(magazine)>[10] <https://en.wikipedia.org/wiki/Before_the_Flood_(film)#cite_note-10> and as 'a heartfelt, decent, educational documentary about the most important issue of our time' by The Guardian <https://en.wikipedia.org/wiki/The_Guardian>. Watching it is free for the next 4 days at: http://channel.nationalgeographic.com/before-the-flood/?gclid=CMHeh6GGj9ACFdbhDQodbdgCRA&gclsrc=ds <http://channel.nationalgeographic.com/before-the-flood/?gclid=CMHeh6GGj9ACFdbhDQodbdgCRA&gclsrc=ds> Warmest regards, Dick
