Our Future Earth

Book excerpt: Paleoclimatologist Curt Stager vividly describes how the decisions we make about the environment in the 21st century will affect the next 100,000 years of life on this planet, and how today's environmental debate is missing the long-term evidence. By considering the Earth's history over millions of years, this book changes our understanding: Most people accept that our planet is warming and that humans played the key role in causing it. We worry about the next few hundred years, yet miss its long-term magnitude. So what will the world look like? Curt Stager draws on geological history to show that the greatest threat to humans will not be global warming, but global cooling. When that hot 'backlash' eventually happens is entirely up to us: We have already put off the next Ice Age, but whether our descendents will see an ice-free Arctic, miles of submerged coasts, or an acidified ocean can still be decided. Whether we continue to pollute or rein ourselves in for the sake of future generations, the world will be vastly different. This lucid book will force climate sceptics, activists, and everyone in between think again about our future earth.
