Yesterday Shell announced it was quitting its Arctic drilling programme. Let me just repeat that in case you, like me, couldn't quite fathom this wonderful piece of news: Shell is quitting its hunt for dirty oil in the Arctic. The thing is about these oil companies is they try and make us believe they rule the world, that their tomorrow is the only tomorrow. But today shows that the future can be rewritten. Shell execs might not publicly admit that our movement stopped them - but reading between the lines we can all see public outrage on Arctic drilling was a huge concern for them.
