Math! How much CO2 by weight in the atmosphere? | small-m According to wikipedia (CO2): As of January 2007, the earth's atmospheric CO2 concentration is about 0.0383% by volume (383 ppmv) or 0.0582% by weight. This represents about 2.996×1012 tonnes, and is estimated to be 105 ppm (37.77%) above the pre ...
Climate and CO2 in the Atmosphere - Earthguide: Educational Resources in Earth, Marine, Environmen Since of the Earth's atmosphere is out-of-balance with the conditions expected from simple chemical equilibrium, it is very hard to say what precisely sets the level of the carbon dioxide content in the air throughout geologic time. While scientists are f
CO2 levels in atmosphere rising at dramatically faster rate, U.N. report warns - The Washington Post Greenhouse gases reached historic highs in 2013, a U.N. report says, in part because of rising emissions from automobiles and smokestacks.

Trends in Atmospheric Carbon Dioxide - NOAA Earth System Research Laboratory The annual mean rate of growth of CO 2 in a given year is the difference in concentration between the end of December and the start of January of that year. If used as an average for the globe, it would represent the sum of all CO 2 added to, and removed
