Greenhouse Gases on Early Earth Helped Keep It Warm
February 7, 2007 / Posted by: Shige Abe
A team of researchers including members of NAI’s University of Colorado, Boulder Team have provided the first direct field evidence supporting the theory that high concentrations of greenhouse gases could have helped avoid global freezing on the early Earth. They analyzed iron carbonates from 3.75-3.8 billion year old rocks in northern Québec, and conclude that the atmosphere of early Earth contained high levels of CO2. Their paper appears in a recent issue of Earth and Planetary Science Letters.
