I am simply searching through PubMed to find reviews of the safety of glyphosate, and this is what I find. You can do the same, it’s a user-friendly searchable database. There is a remarkable consistency to the reviews – they all agree that the evidence does not support an association between glyphosate exposure and any adverse health outcome. The IARC are the only outliers, and yet their flawed and quirky conclusion is the one that garnered the most attention.
There is also a theme in the reviews that we could use more and better quality studies. To put that into context, however, that is almost always the conclusion of such reviews. It is difficult to prove a negative – a lack of a correlation. Such a negative conclusion is only as good as the data supporting it, and therefore the more and more rigorous the data the better the conclusion.
We can always use more and better data when it comes to safety, but the existing data is robust, consistent, and independently replicated, and includes both glyphosate and formulations with glyphosate.
Glyphosate, in fact, is one of the safer pesticides in use (including many organic pesticides). It has replaced far more toxic herbicides. Opposing glyphosate because of unwarranted fears of toxicity is likely to cause harm due to whatever replaces it. Tilling is bad for the soil and releases CO2 into the atmosphere, and we cannot feed the world through hand weeding. Herbicides have to be part of the equation, and glyphosate is one of the safest out there.
Last week EPA Administrator Scott Pruitt stated that: “I think that measuring with precision human activity on the climate is something very challenging to do, and there’s tremendous disagreement about the degree of impact, so no, I would not agree that it’s a primary contributor to the global warming that we see.”
I can only applaud Pruitt’s thoughtful comments, writes Alan Carlin.
But in fact there is not just uncertainty as Pruitt said, but actual evidence that there are no significant effects of rising human-caused emissions or atmospheric CO2 levels on global temperatures.
The Climate-Industrial Complex (CIC) has responded to Pruitt’s comments with all its usual propaganda concerning 97% of scientists, sea level rise, scientific “consensus,” etc., all of which are either incorrect, misleading, or irrelevant to the CIC’s assertion that human activity is the primary contributor to global warming.
