Notes about climate change: 1) code words for taxation 2) code words “it’s your fault YOU caused it. 3) In fact, not much of California was,” says Doris Sloan, a retired UC Berkeley geologist and author of Geology of the San Francisco Bay Region. “The main ice sheets covered Canada and the northern parts of the states in the midwest. Here in California, the ice sheet covered the Sierra Nevada 4) At t the height of the Ice Age, California's mountains were covered by flowing streams of ice up to 60 miles long. Even the higher peaks of Southern California's San Bernardino Mountains were flanked by glaciers. Over time, the glaciers retreated and disappeared. 5) Was there ice in California 18 000 years ago? Between 18,000 and about 6000 years ago, most of the ice melted off of Canada and Scandinavia, causing sea level to rise, flooding the rims of all the dry lands. At the glacial maximum, the central Californian coastline near lay near the edge of the continental shelf, outboard of the Farallon Islands ridge.
