0In this adventure story, the author rides a bicycle back home nearly 3,300 miles in order to witness firsthand how the landscape slowly changes across the vast and diverse North American continent. It took two weeks to navigate across one continental watershed that had been entirely covered by a mile-thick ice sheet a mere 20,000 years ago. One massive glacier had lain right there on the path with, if you were paying attention, the telltale signs of the earthen scars, the piles of rock left behind, and the erratic boulder here and there. It then took 7,000 years for Earth's temperature to slowly rise 9 degrees while that ice sheet retreated to the North Pole. And it took us less than a generation to raise it another 2 degrees from the burning of mined fossil-lightning speed compared to geological time. This first person narrative briefly paints the climate story along the way - the past, present, and future - with over 50 references from scientific journals, news reports, interviews, films, videos, university data, and governmental agencies. It attempts to answer two of the most important questions of our time - What does the path forward look like and who will lead us out of the most daunting environmental challenge humanity has ever faced? Be surprised and enjoy the ride.
