In "Doubt and Certainty in Climate Science," well-known oceanographer Alan Longhurst offers a unique vision of climate change and its scientific study. His deep knowledge of oceanographic research, fishery productivity, and marine ecological changes over several centuries made him doubt some of the postulates of climate science by scientists working on computers with only a few decades of data. In this book, the author reviews what scientists know about climate change, the known unknowns, and the unknown unknowns that give rise to uncertainties about future climate change that is causing far-reaching social and political change. Longhurst provides an incisive critical review of numerous topics in climate change. Beginning with a review of some regional temperature measurements, he questions the robustness of the leading indicator of climate change, a global average of widely differing measurements of sea and land surface temperature. The book offers unique insights worthy of consideration by those seeking to understand climate change, particularly the important role of the oceans in climate.
