This book is a powerful tool for action. It cuts through the politicized rhetoric that too often clouds public discussion regarding climate change by offering practical and manageable advice as to how each of us can take steps that, collectively, can effect meaningful change. I believe it is exactly the kind of synthesis we need, with accessible, up-to-date scientific knowledge that we all will find useful. My scientific research has delved into many aspects of climate science for more than three decades. When I began my career, most ocean scientists expected to see little change in the world’s oceans over the course of their lives. After all, the oceans.
