A Climate Chronology: International Policy, U.S. Policy and Science

The most challenging of all endeavors in human history will likely be that of understanding the impact of our industrial and technological enterprises on the planet’s climate and ecosystems, and responding effectively to the threats posed by that impact. I began writing this chronology while developing a climate policy course at the University of Maine. It has grown substantially during the ensuing six years, and continues to grow. By juxtaposing developments in climate science, U.S. policy, and international policy over the previous century, I hope to give the reader new insights into where we have been, where we are now, and where we may be headed in this formidable endeavor. I welcome comments, and suggested additions to this evolving work. It will be updated every January.

I owe thanks to George Criner, for asking me to develop the climate policy course; to my University of Maine students, game to explore these turbulent waters and mindful of their import for their lives; to my daughter Annya Tisher, who joined me at the Boston Women’s March with the sign, “Climate Change Matters;” and most recently to Patty McCredie, an editor, and Jennifer Linton, a graphic designer, both fellow Climate Leaders in Al Gore’s Climate Reality Leadership Corps, who have been instrumental in developing this interactive website.
