Ten years after his internationally bestselling The Weather Makers, acclaimed scientist and author Tim Flannery argues that Earth’s climate system is approaching a crisis. Catastrophe is not inevitable, but time is fast running out. In the lead-up to the United Nations Climate Change Summit to be held in Paris in December, Atmosphere of Hope provides both a snapshot of the trouble we are in and an up-to-the-minute analysis of some of the new possibilities for mitigating climate change that are emerging now. From atmospheric carbon capture through extensive seaweed farming, CO2 snow production in Antarctica and the manufacture of carbon-rich biochar to reflecting the sun’s rays by releasing sulphur into the atmosphere and painting landscapes and cities white, Flannery outlines an array of innovative technologies that give cause for hope.
