The tipping point for me came on Monday when Oprah Winfrey yelled at her whooping sect-followers: "Global warming is coming!" And she's not the only American big-shot flying the green flag. Angelina Jolie has set up a conservation camp in Cambodia, and on the website stopglobalwarming.org Jon Bon Jovi, Leonardo DiCaprio, James Taylor, Christie Brinkley and Huey Lewis warn us of the perils of climate change. Which is why we in Britain must take global warming seriously. Because we are clearly falling behind in organized celebrity action. Suddenly a nation which has led the way in persuading dinosaur rockers to re-write lyrics in the pretence they're curing poverty is losing ground to America. » original news
