UK must face reality on climate impact of new Heathrow runway

New Scientist 

UK transport secretary Chris Grayling says a new runway planned at London's Heathrow Airport will not meaningfully increase carbon emissions, despite upping the number of flights. There's only one explanation: Grayling's favourite author must be Douglas Adams. In sci-fi series The Hitchhiker's Guide to the Galaxy, Adams creates something called the Somebody Else's Problem (SEP) field, which enables people to simply ignore what they don't want to see. Grayling isn't alone in deploying one – internationally, the top current user is Australian prime minister Malcolm Turnbull, who signed up to the Paris Agreement on reducing carbon emissions with one hand and is backing one of the world's largest coal mines with the other. There are myriad ways to meet a carbon budget, whether those laid down for the UK under the Climate Change Act or global ones determined by climate science.
