There are 415 British MPs who don’t take climate change seriously enough. That is the number who voted to build a third runway at Heathrow earlier this week; 119 of them were Labour. The plans sailed through Parliament, despite some vocal but limited resistance. Only 119 MPs voted against it. Most of them weren’t worried that a third runway would make it near impossible to meet the government’s carbon reduction commitments. They were concerned that the plans were London-centric and might sideline transport projects in the north.
