Based upon warming and carbon dioxide, scientists believe that the Arctic is the leading indicator of global warming. Ice-core samplings have recognized it as the fastest-warming region of Earth. Before the Industrial Age, CO2 levels registered 275 parts per million and for the first time in 800,000 years the Arctic has climbed to 400 ppm. On September 19th the National Snow and Ice Data Center reported that the area has receded to levels not previously known. The Nature Climate Change recently forecasted that the effect of climate change on Northern Hemisphere snowpack through the 21st century in the Western United States, Alpine Europe, Central Asia, the Himalayas and Tibetan Plateau. California, the largest agricultural producer in the country and the 6th largest in the world will be impacted.
