Our Climate Change in Patagonia series
Scientists say in order to maintain a natural balance on Earth, one that provides the environmental conditions upon which all life depends, the amount of carbon dioxide contained in the atmosphere should be below 350 parts per million (ppm). At the beginning of human civilization our atmosphere naturally contained around 275 ppm. Humanity’s growing reliance on coal, oil, and natural gas, or fossil fuels, spiked tremendously the amount of carbon dioxide beginning in the late 20th century. Today, we have 404 ppm of CO2 in the atmosphere, and its rising every year, moving us increasingly farther away from the 350 ppm goal.
