It was clear the author of the post did not read the paper.Simon Donnerhttps://www.blogger.com/profile/01844831377442275615noreply@blogger.comtag:blogger.com,1999:blog-25163458.post-80255934162065447892009-02-06T01:50:00.000-05:002009-02-06T01:50:00.000-05:00It's also quite out of date, as a minute with Goog...It's also quite out of date, as a minute with Google Scholar would have shown. <BR/><BR/>Actually the really sleazy thing about that graph is that it takes Berner's CO2 results and Scotese's completely unrelated temp results and just lumps them together. Of course it was produced by the State of West Virginia's chief mine safety engineer (can we say coal? - yes we can), so no particular surprise there.<BR/><BR/>IIRC more recent work (much of it by Berner et al) has knocked those CO2 levels down considerably.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-25163458.post-17079173960031219362009-02-03T11:15:00.000-05:002009-02-03T11:15:00.000-05:00I've simply presented what the scientific communit...I've simply presented what the scientific community knows about early corals, by deferring to the author of the TEXTBOOK about the corals history and diversity. That early corals secreted calcite not aragonite is widely accepted. <BR/><BR/>The speculation is in the Watts post -- first, there's no mention that early corals were capable of withstanding higher CO2 than today's scleractinia, and second, there's no mention of the fact that the 500 million year + CO2 reconstruction is highly uncertain.Simon Donnerhttps://www.blogger.com/profile/01844831377442275615noreply@blogger.comtag:blogger.com,1999:blog-25163458.post-44375974014614622592009-02-03T10:33:00.000-05:002009-02-03T10:33:00.000-05:00I get the impression that there is a lot of specul...I get the impression that there is a lot of speculation going on here and not a lot of actual knowledge.
