Carbon Cycle Bold Kids

The main ways that humans add to much carbon in the earth's carbon cycle are burning fossil fuels, and eruptions. Throughout much of human history, volcanoes have been the largest producer of carbon dioxide in the earth's carbon cycle, although in recent years, humans burning fossil fuels have also added a great deal to much more carbon in the earth's carbon cycle. Although it seems that volcanoes do not cause much change in global temperatures, they can greatly affect global climate. After a long period of time, especially if the volcano has not erupted for a long time, a eruption can take place, spewing out a great amount of greenhouse gases into the atmosphere. This is known as a shockwave; this change in atmospheric pressure can significantly alter the earth's climate.
