Is that anything like saying, "The hypothesis on Global Warming doesn't have any significant scientific support?"  I'm not saying it doesn't, but it's wrong for you to suggest that there's no scientific support against anthropogenic GW, the same as saying there was no scientific support for global cooling then.  Perhaps the reason there is so much more support for GW than global cooling in the 70's is that information and studies are so much more available these days.  Maybe the reason GW is such a big deal now is because places like MySpace and MTV make it so much more marketable.  Personally, I see a lot of hype and not a lot of proof.
