How can they be sure its not caused by global warming?
That KNOW website has a great explanation, thanks for providing that Joe.
But, Joe, your Global warming tangent – that is an example of a “knight’s move” in the thinking and speech typical of people with Asperger’s syndrome, or, high-functioning autism.
All the medical-establishment literature will deny the link between autism/Asperger’s and mercury in vaccines, but deep within the fine print of their own studies is the suggestion that in some subgroup of more-vulnerable individuals there appears to be a correlation between vaccines in infancy and Autism Spectrum disorders (I wish I could find this…)…. and yet, the medical establishment still refuses to study this subgroup effect in more detail.
They are statisticians, they [ought to] know that when they only study very large general population groups, that it’s like throwing a cup of saltwater in an Olympic size pool, stirring it up a bit, then taking a random sample of the pool water and saying, No saltwater can be detected, therefore there is no saltwater in the pool!
