The Unknown Unknowns of Global Warming

Posted on October 29, 2011 by

Plants, both through decay and respiration, are responsible for over half of the world’s annual carbon dioxide emissions. I mention this fact for one reason and that is to communicate the power of the biosphere upon the atmosphere. Usually, when … Continue reading →

Visualizing the “Greenhouse Effect” – Atmospheric Windows

Posted on February 28, 2011 by

Guest post by Ira Glickstein A real greenhouse has windows. So does the Atmospheric “greenhouse effect”. They are similar in that they allow Sunlight in and restrict the outward flow of thermal energy. However, they differ in the mechanism. A … Continue reading →
