Wikipedia lists fifty-three books that are currently available on the subject of climate change, and this new book will make fifty-four. Such books fall into one of two groups: they either support the orthodoxy or dissent from it. Tony Eggleton’s book is one that supports it. It is well written, clear in its argument, quite even-handed, and comprehensive. I enjoyed reading it, even though I have my criticisms. Why do I criticise? Because I am a dissenter.
