   Well, Doug, the Devil can quote scripture. At least, that is what he tells

   The paper says substantially what Gene reported. From the Abstract:

   “...has not only survived these environmental changes, but has maintained
   its distinct skeletal biomineralization pattern for at least 40 My.”

   Well, all of the wording in Gene's message other than the article reference
   was from the "CO2 Science" website, except where it quotes the article.  The
   "CO2 Science" website is a denier propaganda website, put out by Idso, Idso,
   and Idso.  The first Idso is  "An outspoken [2]global warming denier known
   for  claiming  that  rising  CO[2] levels  will  have  mainly positive
   environmental effects" (Wikipedia:
        The last half of the last paragraph in Gene's message is likely not
   supported by the article at all.

     I will plead ignorance as I have not read the paper…but as scientists of
     living systems - interacting with their non-living systems know, it is as
     much about the speed and nature of change in the non-living systems as the
     change itself that controls biological system response.  Documenting
     historical change is not enough empirical evidence.  There is a nuance to
     the nature of that change that needs to be captured too.  Again, maybe it
     was captured in the paper I don’t know.  But the synopsis below is far too
