LINKS, damnit, I want LINKS!!!
Good overall article on the subject;
http://grist.org/business-technology/so-...t-exactly/
Here's some interesting reviews of the IARC decision, a mixed bag of support, faint at best and damning more the norm;
http://www.sciencemediacentre.org/expert...ncer-iarc/
Some excerpts;
"...“This sounds scary and IARC evaluations are usually very good, but to me the evidence cited here appears a bit thin..."
"...“IARC bases its conclusions on an evaluation of the human and experimental data, leading to hazard identification. They ask: is a substance carcinogenic? And if so, how good is the evidence in humans?
The IARC process is not designed to take into account how a pesticide is used in the real world – generally there is no requirement to establish a specific mode of action, nor does mode of action influence the conclusion or classification category for carcinogenicity..."
“The IARC process is not a risk assessment. It determines the potential for a compound to cause cancer, but not the likelihood.
"...There are over 60 genotoxicity studies on glyphosate with none showing results that should cause alarm relating to any likely human exposure. For human epidemiological studies there are 7 cohort and 14 case control studies, none of which support carcinogenicity.
The authors have included non-Hodgkin lymphoma (NHL), but that diagnosis is no longer used in pathology because it’s far too imprecise. Even if you do include NHL there are still 7 studies, only one of which is positive – and that one is not a good study in my view. The weight of evidence is against carcinogenicity..."
Here is perhaps the most extreme statement made by any of the commentators;
"...IARC have carefully assessed new evidence about the cancer hazards of pesticides, and have now classified 5 pesticides as either ‘probably’ or ‘possibly’ carcinogenic to humans. The authorities in the EU must now consider whether existing measures are sufficient to protect consumers and pesticide applicators from cancer risks. This will be particularly important for the widely used weedkiller glyphosate..."
however that reviewers statement regarding "new evidence" was contradicted by a later reviewer;
"...“IARC monographs do not present new primary research. Rather they rigorously and systematically review the available evidence from published peer-reviewed studies in animals and humans in order to classify chemicals according to their cancer hazard (i.e. their potential to cause cancer at some level of exposure) in animals and in humans..."
Here's a link to the Monograph on glyphosate, just released by IARC after criticism of releasing their findings before the actual study;

Here's a link for the full IARC list; ( Edit: this link is redundant, Obie and rj #128076; )
http://monographs.iarc.fr/ENG/Classifica...pOrder.pdf
For a bit of (perverse) levity scroll past the 2B list with glyphosate and to the "safer" (only possibly cause cancer instead of probably) and see Chlorodane on page 10 and DDT on page 11, followed thereafter by Gingko bilboa, Goldenseal root powder, and Heptachlor!
Man, don't post that at the Natch!
