    • Removal of Atmospheric Carbon Dioxide 

  • Carbon dioxide (CO2) is a colorless and odorless gas vital to life on Earth. Carbon dioxide exists in Earth's atmosphere as a trace gas at a concentration of about 0.04 percent (400 ppm) by volume. Natural sources include volcanoes, hot springs and geysers, and it is freed from carbonate rocks by dissolution in water and acids. Carbon dioxide is soluble in water, and occurs naturally in groundwater, rivers, lakes, ice caps, glaciers and also in seawater.

    • • • Since the start of the Industrial Revolution around 1750, we have been adding substantial amounts of carbon dioxide (CO2) and other greenhouse gases (such as methane, nitrous oxide, and fluorinated gases) to the atmosphere. Greenhouse gases trap infrared radiation in the atmosphere, which makes the Earth warmer.
