Join local historian James Kences as he continues his engaging review of the history of hydrocarbons and their extraordinary presence in almost every aspect of modern life. This is the second of Mr. Kences’s two-part research report and discussion of fossil fuels and how they became an engine of our civilization. He writes, “An understanding of the history of the climate hypothesis… eventually led to an awareness of the “Greenhouse Effect,” and to the role of carbon dioxide in retaining the sun’s heat. We now know of the fragility of the climate and the multiple inter-connections, and of the resemblance to falling dominoes. Each part of the great puzzle was assembled by a systematic gathering of evidence. Knowledge of how and when that evidence first took form will be the subject of my presentation.”
