The Great Global Warming Swindle, Part 3

2009-07-21 20.04.44The past few days I have been sharing parts of The Global Warming Swindle at Dakota Voice.  The Global Warming Swindle presents a clear look at the hysteria surrounding the theory of anthropogenic (man-made) global warming and features testimony from many respected scientists.

In Part 3 we see a bit of Al Gore’s “An Inconvenient Truth” propaganda film. Ice core data and the comparison of CO2 and temperature are a key component of Gore’s contention.

We didn’t really get the whole picture from Gore, though.

Dr. Ian Clark of of the Department of Earth Sciences at the University of Ottowa is a leading arctic paleoclimatologist and he took a look at this ice core data and found that the link was the opposite of what Al Gore claimed.

In other words, the data shows that CO2 increases aren’t driving temperatures, but rather temperature increases are driving CO2 increases.

Several addition ice core studies have found the same thing: CO2 levels following–not driving–temperature changes.

How can this be?  After all, the “mainstream” media and pop culture have for years fed us a rich diet of pap which claims CO2 drives temperature.

Well, CO2 is a natural substance.  It is generated by you and me and animals and many other natural sources, including volcanoes which make human contributions pale in comparison.  Dying vegetation and the oceans release countless tons of it.  Even all life on earth is carbon-based.

Professor Carl Wunsch of the Department of Oceanography at MIT says the oceans both absorb large amounts of CO2 from the atmosphere and release large amounts of CO2 into the atmosphere. He says if the ocean is heated, it tends to release carbon dioxide (which might explain why CO2 rises follow temperature increases, which also tend to follow solar activity).  The ocean covers the vast majority of the earth, and so not only has a large influence on global conditions, but because of that immense size, changes often lag for hundreds of years.

Solar physicist Dr. Piers Corbyn decided to try monitoring solar activity to predict global climate patterns and found it remarkably accurate.  Historical data going back hundreds of years indicates a correlation between sunspot/solar activity and global temperatures.

If you missed them, be sure to catch Part 1 and Part 2.
