<p>The current average global temperature is within half a degree Celsius (one degree Fahrenheit) of what Svante Arrhenius' calculated 100 years ago that the current carbon dioxide level in the atmosphere would produce. That fact was pointed out by Bassam Shakashiri, past president of the American Chemical Society, at the old geezers' ("senior chemists") breakfast at a recent society meeting in Denver.</p>
<p>Dr. Shakashiri emphasized the importance of informing the public about the science of global warming (the facts) as distinct from the politics (the arguments about what we should do about it).</p>
<p>If you want to learn more about the science, I would suggest that you Google "Svante Arrhenius global warming." You will find his original 1896 paper, bibliographical information, and the history of scientific developments in the field. Some of the articles are pretty technical, others simplify the science to where anyone should be able to understand it.</p>

<p>The fourth listing on the Google search Matteson recommended today leads to "The<a name="L000"></a> Carbon Dioxide Greenhouse Effect" article from the American Institute of Physics <a href="http://www.aip.org/history/climate/co2.htm">http://www.aip.org/history/climate/co2.htm</a> that I have posted numerous times to Vision2020, one of the best easily understood histories of climate science I have read. Links on the right side of the article will take the reader to more technical science, if they wish.</p>
<p>There are numerous credible sources that summarize climate science, but the following two I've found especially competent and easily understood: Professor Scott Mandias presentation of climate science here: <a href="http://www2.sunysuffolk.edu/mandias/global_warming/">http://www2.sunysuffolk.edu/mandias/global_warming/</a> And Barton Paul Levenson's climate science pages here: <a href="http://bartonpaullevenson.com/Climatology.html">http://bartonpaullevenson.com/Climatology.html</a></p>
