A study of how successful campaigns to curb dangerous chemicals and pollution point to a way forward on climate change.

Apocalyptic despair over the issue of climate change is common. However, according to veteran atmospheric chemist Solomon, it is a waste of energy that could be productively employed. She has won acclaim for her four decades of work in her field, and in this book, she examines how a range of environmental crises have been addressed. She was directly involved in some, such as repairing the hole in the ozone layer; regarding other projects, she has drawn together extensive primary and secondary research. Compiled in this way, the list is surprisingly long, including the removal of lead from paint and gasoline, the banning of dangerous pesticides, and reductions in air pollution and acid rain. The ban on chlorofluorocarbons, writes the author, provides a framework for effective cooperative action. Beginning with scientific research, the process moved to policy changes in a few countries, followed by global agreements and workable regulation and action. Problems bring forth answers, which might be new technology or a change in thinking. Trying to bully people into acceptance of painful reform is usually counterproductive. Explanation and persuasion might be slow but will be more effective in the end. In relation to the climate change debate, Solomon does not underestimate the problems, but she believes that a tipping point for dynamic action has been reached. “If we seize the day within this decade, we can craft a better future for life on Earth,” she writes. “Understanding the basic science, the global politics, key economic factors, and the essential roles of the public and of technology-steering shows that the world is on the cusp of a brighter future.”

Solomon’s review of answers to big problems displays her expertise and optimism in a pragmatic, inspiring package.
