Climate change

Official advice about climate change is all about cutting car use or changing lightbulbs. Of course we need to find other ways of getting about, work more from home, do our bit. But the powers are in a position to make a real difference. Stiffer taxes for high-polluting vehicles are overdue (though it's unfair to impose them retrospectively), but what about high-polluting buses? What about the array of 24-hour traffic lights that treat us like zombies, cost the earth to install and run, and maximise emissions from the stop-start drive cycle? The authorities preach and dodge blame, but they are the ones who need to act. Meanwhile, the waste and carnage go on.
