They tell us that levels of carbon dioxide (CO 2) in the atmosphere are higher than they have been at any time in the past 400,000 years. During ice ages, CO 2 levels were around 200 parts per million (ppm), and during the warmer interglacial periods, they hovered around 280 ppm (see fluctuations in the graph). Parts-per million (ppm) is a common quantity used in many areas of math and science. It can be somewhat difficult for some to understand because it is not a true unit. In fact, ppm is a unitless quantity. It is analogous to percent.
