A companion article at ArkFab shares my thoughts on peer review in regards to this project and DIY/community/citizen science in general. 

At long last, the much-anticipated booklet, “CO2 Trouble: Ocean Acidification, Dr. Everett, and Congressional Science Standards” is available and approved for human consumption! Download and share HERE (or at Scribd HERE).

In this document, I have bundled, updated, and expanded my series of essays debunking the congressional testimony of Dr. John Everett regarding the environmental chemistry of carbon dioxide.

It has been designed to be a fairly short (less than 30 pages, including images, appendicies, etc.) and accessible read. It has been challenging but fun to write; I have had to learn a lot about GIMP, Python, Scribus, social networking, and of course ocean acidification to get to this point.

It was also very useful for me as an opportunity to go back through my earlier remarks and double-check my work. For example, I later realized that the documentation which Dr. Everett provides for his CO2 data in part two is ambiguous: Although the citation for the rate data is referred to as “Recent Global CO2”, the URL provided links to the longer record as measured at Mauna Loa Observatory. This confusion had led me in the past to make incorrect claims about some of the figures he presents. Ultimately it was inconsequential to my argument, but it was frustrating to have to deal with such ambiguities. On the other hand, this led me into comparing the Mauna Loa record with the global record (Appendix B) which was an interesting exercise.

In researching this project, I also came across new phenomena I wasn’t previously aware of. For example, while I was calculating historical rates of CO2 change, I ran though the 1000-year Law Dome record and saw this:

Pre-1750 CO2 rates, based upon the Law Dome ice cores. There appears to be both a clear periodicity and a major perturbation in this record. I wonder why? Clyx for teh Datumz!

Not only does there appear to be a centennial-scale oscillation in the preindustrial CO2 accumulation rate, there is a clear perturbation around 1500-1700. Intriguingly, these dates roughly correspond to the start of the Little Ice Age. In fact, some have pointed to the decline in CO2 as measured by the Law Dome data as evidence for a speculative but intriguing explanation for the LIA: depopulation caused by the Black Death reversed land use trends, causing reforestation of agricultural land and removing carbon from the atmosphere. I am unfamiliar with the oscillation, however – if you know more about it, or would like to help me  crunch these numbers more thoroughly, let me know 🙂

Stay tuned for more updates – coming up is an austere, printer-friendly version, a zine version, press information, and more. And be sure to check out the report, which contains unreleased material. Velociraptors figure prominently (really!)
