Started to worry about just how hot our world is going to get, and whether you can do anything about it? As the effect of climate change grows by the day, so does the amount of hot air and bluster spouted by politicians and businessmen on what we should do about it. What with the excuses, the lies, the fudged figures, the PR greenwashing and the downright misinformation on the power of everything from wind turbines to carbon trading, when it comes to saving the world, most people don't know what they're talking about. Luckily, George Monbiot - scourge of big business, riler of governments, arch-enemy of climate change deniers everywhere - does. Packed with killer facts and inspiring ideas, shot through with passion and underlined by brilliant investigative journalism, with a copy of ''Heat'' you really can protect the planet. 'I defy you to read this book and not feel motivated to change' - ''The Times''.
