Book review: can science fix climate change? by Mike Hulme

As political solutions to climate change have so far had little impact, some climate change scientists are now advocating the so-called ‘Plan B’, a more direct way of reducing the rate of future warming by reflecting more sunlight back to space, creating a thermostat in the sky. In this book, Mike Hulme argues against this kind of hubristic techno-fix. Amelia Sharman is impressed by Hulme’s interesting proposals.
