Canadian Essentials

For two years the COVID-19 pandemic has upended the world. The physician and medical historian Jacalyn Duffin presents a global history of the virus, with a focus on Canada. Duffin describes the frightening appearance of the virus and its identification by scientists in China; subsequent outbreaks on cruise ships; the relentless spread to Europe, the Americas, Africa, and elsewhere; and the immediate attempts to confront it. COVID-19 next explores the scientific history of infections generally, and the discovery of coronaviruses in particular. Taking a broad approach, the book explains the advent of tests, treatments, and vaccines, as well as the practical politics behind interventions, including quarantines, barrier technologies, lockdowns, and social and financial supports. In concluding chapters Duffin analyzes the outcome of successive waves of COVID-19 infection around the world: the toll of human suffering, the successes and failures of control measures, vaccine rollouts, and grassroots opposition to governments' attempts to limit the spread and mitigate social and economic damages. Closing with the fraught search for the origins of COVID-19, Duffin considers the implications of an "infodemic" and provides a cautionary outlook for the future.

Pandemics, massive earthquakes, war, and other catastrophes inspire immediate action because their casualties and destruction are immediately visible. Climate change is an unyielding problem because its long-range dangers are hidden, and thus it is a global risk unlike anything in human experience. The federal government recently announced aggressive climate targets for Canada. We have committed to producing net-zero greenhouse gas emissions by 2050, which will require major changes for our economy and way of life. Canadian citizens need to understand why our most distinguished climate scientists and our senior political leaders think that we must meet this target. Canada and Climate Change explains the importance of policies that will ensure we meet the net-zero emissions target. William Leiss provides a firm grasp on what climate change is and how scientists have described shifts in the earth's climate as they have occurred over hundreds of millions of years and as they are likely to occur in the near future, especially by the end of this century. Leiss argues that citizens have a right to place their trust in what climate scientists tell us. “Canada and Climate Change” is an essential primer on where we stand on the issue of climate change in Canada and what will unfold in the years ahead.
