Global warming is one of the gravest dangers confronting us today. The 20-year, quixotic efforts of activists in the USA to warn the public about the risks of climate change are captured in the "documentary cartoon" Everything's Cool. It features among others journalists such as Ross Gelbspan and Bill McKibben, The Weather Channel's Dr Heidi Cullen and government official Rick Piltz, who has fought pressure from the US administration to censure annual climate reports. For years, these veterans have been battling to achieve recognition of the problem of global warming in the face of politicians' ridicule, bent scientists and partisan lobbyists.
