Note the colors change as the amount of CO 2 rises from 365 parts per million (ppm) in 2002 to over 420 ppm currently. The animated map shows how the historical changes in global carbon dioxide over time. This human-induced rise is greater than the natural increase observed at the end of the last ice age 20,000 years ago. Since the onset of industrial times in the 18th century, human activities have raised atmospheric CO 2 by 50% – meaning the amount of CO 2 is now 150% of its value in 1750. The second graph shows CO 2 levels during Earth’s last three glacial cycles, as captured by air bubbles trapped in ice sheets and glaciers. The first graph shows atmospheric CO 2 levels measured by NOAA at Mauna Loa Observatory, Hawaii, since 1958. Human activities have raised the atmosphere’s carbon dioxide content by 50% in less than 200 years.Ĭarbon dioxide (CO 2) is an important heat-trapping gas, also known as a greenhouse gas, that comes from the extraction and burning of fossil fuels (such as coal, oil, and natural gas), from wildfires, and natural processes like volcanic eruptions.
