This wide-ranging book is part science, part philosophy. It takes a long and broad view, into both the past and the future, of planetary and human history.

Mankind suddenly finds itself running a planet – a role neither anticipated nor sought – without knowing how it should be done. We’re at the controls but we’re not in control. This book examines how we got into this situation and where that leaves us now.

Climate change is the most obvious of the ways in which we have begun to alter our planet. Scientists are beginning to say that we have entered a new epoch in which the net activity of humans has become a powerful agent of geological change – the Anthropocene, the age of Humanity.

Grinspoon begins by describing the history of Earth and how and why life evolved here when it didn’t on neighbouring Mars and Venus. He then addresses climate change and other catastrophes currently being caused by human activity. He presents the latest scientific knowledge and speculation in the fields of planetology and astrobiology and discusses the rationale for naming the current epoch Anthropocene. He concludes that we are at a bottleneck. If humanity can develop the global wisdom and cooperation to make it through this century, we will likely then emerge as not just a technological society but one with a mature planetary intelligence. He optimistically names this state Terra Sapiens – Wise Earth. We can only hope this happens.

Along the way, there is a lengthy discussion about SETI, the Search for Extraterrestrial Intelligence, reviewing the options for the search and the wisdom of undertaking it. This is followed by looking at the more controversial Active SETI (METI) which, in addition to passively searching for alien life, would involve sending messages to broadcast our presence.

Grinspoon’s conclusion is optimistic. He believes that humanity has the innate tools to make it through this bottleneck by building a global, cooperative, mature intelligence on Earth. We require only the will to do so and time is running out.

Although there is a certain amount of repetition, this is well written and very thought-provoking. It is an engaging and enjoyable read, often poetic in parts.

About to pen a climate fiction series subsequent to my climate novel Pinatubo II, and this book may influence the storyline outcome(s)--positive or negative. https://0urnearfuture.wordpress.com/books/
