The No Logo of climate change – a book that shows how global warming is not a theory we should still debate, but something that has already happened on a global scale.

Climate change is not a concern for the future. It's happening right now. In this book – based on the latest scientific evidence – the author takes us around the world to show the impact of global warming already being felt in people's lives.

From sand-buried houses in China to thawing Alaskan plains, the author witnesses some of the worst effects of climate change at first hand. Some, like the floods in the UK, are near home. Others – like the drowning Pacific island of Tuvalu – are a world away from the exhaust pipes and factory chimneys that are actually causing global warming.

But this isn't simply an inventory of disaster, it's a wry look at how people around the globe are coping as their world changes at unprecedented speed. In the process, the author eats whale blubber in Alaska, swims in shark-infested waters off the Great Barrier Reef and struggles to the top of Andean peaks in Peru. An adventure with a conscience and an argument with an urgent purpose, High Tide is an extremely important book.

‘With High Tide, Mark Lynas has given us a tremendous gift: he has time-travelled into our terrifying collective future, a future that has already arrived in the farthest reaches of the globe. Go with him on this breathtaking, beautifully told journey – to island nations being engulfed by rising tides, to towns swallowed by encroaching desert, to glaciers melting into oceans – and I promise that you will come back changed, determined to alter the course of history.’
Naomi Klein, author of No Logo

‘Clear, lucid and informative.’ New Statesman

‘A thoroughly engaging and well-researched book.’ TLS

‘If you are among those who think climate change is an uncertain, remote issue over which scientists are unsure, politicians talk endlessly to little effect, and mere individuals have no power at all, this book may be for you … Lynas tells us to keep repeating the climate change message. Read his book, and that is exactly what you will do.’ Guardian

‘There will be many more books like High Tide, but this will be remembered as the first … it’ll be the one with the original vision … Not unworthy of comparison with Orwell and certainly the breaker of new ground.’ Independent
