The Guardian details the expert testimony marshaled by the activists:
The court had heard from Professor Jim Hansen, one of the world's leading climate scientists, that the 20,000 tonnes of carbon dioxide emitted daily by Kingsnorth could be responsible for the extinction of up to 400 species. Hansen, a Nasa director who advises Al Gore, the former US presidential candidate turned climate change campaigner, told the court that humanity was in "grave peril". "Somebody needs to step forward and say there has to be a moratorium, draw a line in the sand and say no more coal-fired power stations."
It also heard [opposition leader] David Cameron's environment adviser, millionaire environmentalist Zac Goldsmith, and an Inuit leader from Greenland both say climate change was already seriously affecting life around the world. Goldsmith told the court: "By building a coal-power plant in this country, it makes it very much harder [to exert] pressure on countries like China and India" to reduce their burgeoning use of the fossil fuel.
The court was told that some of the property in immediate need of protection included parts of Kent at risk from rising sea levels, the Pacific island state of Tuvalu and areas of Greenland. The defendants also cited the Arctic ice sheet, China's Yellow River region, the Larsen B ice shelf in Antarctica, coastal areas of Bangladesh and the city of New Orleans.
The jury was told that Kingsnorth emitted the same amount of carbon dioxide as the 30 least polluting countries in the world combined – and that there were advanced plans to build a new coal-fired power station next to the existing site on the Hoo peninsula.
