People are organising the showing of this film in community centres all over the UK.
In November last year, a group of experts delivered speeches about the state of the world as it relates to climate and especially the effects it will have on the people living in the UK.
What will be different this time is watching it with about 200 other people, some of whom will be hearing the news for the first time. Others may know a lot, but the unvarnished truth will hit hard. I am fascinated to see how people react.
The truth is dark - it is hard-hitting - it makes the need for real climate action clear and the urgency real. There is only so long that we can keep ignoring it. If we are willing to hear this and act on it we can still mitigate the worst effects.
Another aspect will be the debate after it. Our representative (MP) will be in a debate with two others. He has always paid lip service to the issue.
If you can, try to get to see it.
