It's time to stop just worrying about climate change, says Paul Gilding. Instead we need to brace for impact, because global crisis is no longer avoidable. THIS GREAT DISRUPTION started in 2008, with spiking food and oil prices and dramatic ecological change like the melting polar icecap. It is not simply about fossil fuels and carbon footprints. We have come to the end of Economic Growth, Version 1.0, a world economy based on consumption and waste, where we lived beyond the means of our planet's ecosystems and resources. THE GREAT DISRUPTION offers a stark and unflinching look at the challenge humanity faces - yet it also contains a deeply optimistic message. The coming decades will see loss, suffering, and conflict as our planetary overdraft is paid. However, they will also bring out the best humanity can offer: compassion, innovation, resilience and adaptability. Gilding tells us how to fight, and win, what he calls 'the One Degree War' to prevent catastrophic warming of the earth, and how to start today. THE GREAT DISRUPTION is an invigorating and well-informed polemic by an advocate for sustainability and climate change who has dedicated his life to campaigning for a balanced use of Earth's limited resources. It is essential reading.
