Clearing the Air by Tim Smedley

Being Friday, there were more climate protests today and new books related to environmental issues continue to appear. One is CLEARING THE AIR by Tim Smedley which was shortlisted for the 2019 Royal Society Science Book Prize. In the prologue, Smedley notes his initial surprise when he started to learn more about “the most immediate environmental issue of all: the air we breathe.” He certainly does cite disturbing statistics: “In late 2016, the World Health Organisation (WHO) announced that outdoor air pollution caused over 3 million deaths worldwide; by 2018, the WHO revised this up to 4.2 million.” Smedley’s work tends to be rather UK-centric, although he adds graphic examples from around the world, like describing half-marathoners running in Delhi, India while wearing face masks or Beijing, China citizens complaining of persistent coughs. Smedley argues that air pollution is gradual, persistent and largely invisible so humans are less inclined to take drastic action. Hoping this will change, he notes that “modern science is starting to reveal what our eyes cannot see: an anonymous killer born from the cars in our driveway and the industrial processes used to make the products in our cupboards."  Offering chapters split between Origins (e.g., The Dash for Diesel) and the Fightback (e.g., Electric Dreams), Smedley concludes with an epilogue containing a Clean Air Blueprint for cities and for his individual readers. CLEARING THE AIR includes an index and provides details for a limited set of references.
