Mauna Loa CO2 Concentration Exceeds 400 ppm in May, 2014

“The late renowned scientist, Charles David Keeling, , began keeping daily measurements of atmospheric carbon at Mauna Loa in 1958ma and his record is known as the “Keeling Curve”” – Daily KOS 

I have been tracking the Mauna Loa CO2 levels with this chart in this blog  sidebar for several years. The May, 2014 monthly CO2 level crossed the 400 ppm threshold for the first time at Mauna Loa since keeling started CO2 observations their in 1958,  so I decided to show CO trend in full size.

Understanding the Science of CO2’s Role in Climate Change: 2 – Electromagnetic Radiation and Earth’s Climate

This post, the 2nd (1st post here) in the series on Understanding the Science of CO2‘s Role in Climate Change, discusses several electromagnetic radiation topics:  1) electromagnetic spectrum basics, 2) essential climate related electromagnetic radiation physics, and 3) the Sun  and Earth’s electromagnetic radiation spectra.

I present the basic formulas and 3 R based charts that I have developed to help readers get a sense for the underlying physics and to provide a basic  foundation for understanding the climate related properties of greenhouse gases and the energy balance models presented in upcoming posts.I have also included an Excel workbook with these basics formulas.

CO2: Emissions & Changes in Atmospheric Levels

In previous posts, I have shown the 1750-2008 global CO2 emission trends and the atmospheric CO2 concentrations at Mauna Loa, Hawaii. In this post, I compare annual CO2 emissions with annual changes in atmospheric CO2.  The resulting chart shows the portion of CO2 emissions that remains in the atmosphere and the portion that is soaked up by the land & ocean.  Links to the R script and source data files are provided.
