History offers us an insight into what it takes to cause government to act. Figures vary but the 'Great Smog of London' (1952) probably killed around 10,000 people, both immediately and across the following few years. Four years later, the Government introduced the 'Clean Air Act' which drastically reduced the causes of air pollution which led to the Great Smog. Industry and the ordinary citizen were equally affected by the changes that the Act required. But 10,000 deaths ensured that the legislation, no matter how challenging, was implemented by everyone.
How many deaths worldwide will be required for governments to take similar action to address 'climate change'?
