Urgent and inspiring lessons from the frontlines of the climate catastrophe - by one of our most important and influential environmental writers. ** A New Yorker Best Book of the Year ** From Greenland's melting ice sheets to New Zealand's protected mountaintops, we join Kolbert on the road as she travels to the places most dramatically affected by climate change - revealing a world which is both dangerously fragile and remarkably resilient. We encounter newly discovered species and meet the last surviving members of others, witness the power of rewilding up close and are reminded of the abounding wonders of our natural world. Along the way we also meet countless brilliant individuals who are steering us towards a better future: scientists harnessing AI to commune with whales; activists successfully lobbying for the rights of nature; and ordinary people making extraordinary moves, such as the Samso islanders leading completely carbon-neutral lives. The natural world is changing profoundly, and the threats to our planet are only growing more serious. Now is the time to deepen our understanding of this incredible world we are in danger of losing - and to act, while we still can.
