A straightforward and fact-based exploration of how weather happens, how it relates to climate, and how science answers major questions about Earth as a system Climate change is one of the most hotly contested environmental topics of our day. To answer criticisms and synthesize available information, scientists have been driven to devise increasingly complex models of the climate system. This book conveys that the basics of climate and climate change have been known for decades, and that relatively simple descriptions can capture the major features of the climate system and help the general public understand what controls climate and weather, and how both might be changing. Renowned environmental scientist and educator John D. Aber distills what he has learned from a long fascination with weather and climate, the process of science, and the telling of the story of science. This is not a book about policies and politics. Instead, it explores how weather happens, how it relates to climate, and how science has been used to answer major questions about the Earth as a system and inform policies that have reversed environmental degradation. By providing a guided tour of the science of weather, this thoughtful survey will contribute clarity and rationality to the public understanding of climate change.
