“Greenhouse gases, like carbon dioxide, absorb infrared energy and help warm the planet. So they're absolutely crucial. The problem is that their concentration in the atmosphere needs to be regulated as the sun slowly brightens. Otherwise, the Earth would not be able to stabilize its surface temperature, which would be disastrous. Plate tectonics cycles fragments of the Earth's crust -- including limestone, which is made up of calcium, carbon dioxide, and oxygen atoms -- down into the mantle. There, the planet's internal heat releases the carbon dioxide, which is then continually vented to the atmosphere through volcanoes. It's quite an elaborate process, but the end result is a kind of thermostat that keeps the greenhouse gases in balance and our surface temperature under control. --Guillermo Gonzalez, Ph.D. (astronomer & physicist)”
