Part VI of John Everett’s testimony is a criticism of a geoengineering approach to ocean acidification. I agree with his conclusion (that adding alkaline calcium carbonate to the oceans is not a useful approach to ocean acidification) but nevertheless find this section to be problematic. I’ll return to it once I’ve finished with the rest of his testimony.
Part VII is a collection of research suggestions “that would go a long way toward establishing the likely effects of an increased CO2 world.” On the surface, it’s hard to take issue with his suggestions, but in the context of the rest of his testimony, they ring rather hollow.
For example, his first research suggestion is the development of
“a CO2/temperature timeline based on extant research on past climates, at least back to about 600 million years before the present. This effort would provide a critical review of candidate papers and unpublished work that goes well beyond a typical peer-reviewed journal publication, or prior summary reports of the IPCC.”
I think that it would be great to have a comprehensive review of the state of paleoclimatology and paleogeochemistry. But Dr. Everett ignores what we already know about those topics– so what good would such an effort be?
