We like to frame climate change as a black and white issue: are you with us or against us? Is it our fault, or is it all natural? Are we screwed, or is there nothing to worry about? Is the polar ice melting or growing? Tamsin Edwards tells the real, more nuanced story of climate science, which contains opposites, uncertainties and shades of grey. This is a personal journey into the science and life of a scientist: how climate science works, how to deal with polarisation, and how we as scientists – and humans – can make sense of a complex and uncertain future.
