Scientific consensus on GMO safety and climate change

scientific consensus on GMO

A scientific consensus is one of the most powerful principles in science, sitting just below the predictive power of a scientific theory. In general, a scientific consensus is the collective opinion and judgement of scientists in a particular field of study. This consensus implies general agreement, and disagreement is limited (sometimes from individuals who are not experts in the field) and considered insignificant.

This lead me to a search for the prevailing scientific consensus on GMO safety and climate change.

For clarity, the major difference between a scientific theory and a scientific consensus is that a theory is essentially considered a fact. The theory of gravity is a fact. The theory of evolution is a fact. A theory is so predictive, it is supported by so much evidence, and it is so well accepted, it would take an incredible amount of data to refute it.

The only thing that matters in forming a scientific consensus or theory is evidence. Not rhetoric. Not debate. Not opinion. Not political expediency. Not logical fallacies. Just evidence.

I’ve written about the scientific consensus on GMOs, and it is clear that nearly every independent scientific organization across the world agrees that GMOs are safe for humans and/or the environment. Moreover, most of these same organizations provide a similar consensus about climate change–ironically, there is a significant portion of people who deny one consensus but accept the other, despite the fact that the consensus for both scientific principles are based on nearly overwhelming evidence.

On the next page, I will review the statements of seven prestigious scientific organizations across the world for the scientific consensus on GMO safety and on climate change.

GMO scientific consensus – it’s broad and unequivocal, they’re safe

GMO scientific consensus

I have been writing about the GMO scientific consensus for quite some time, because this scientific consensus for the safety of GMO crops is so overwhelming that it’s almost impossible to ignore. Let me put it this way – if you accept the enormous evidence that supports the scientific theory of climate change, then you should know that there is almost the same volume of evidence that supports the safety of genetically modified foods.

If you accept the science of climate change, but deny the science of GMOs, then you are a science denier. It’s pretty simple. In fact, many of us think that GMO deniers are the left’s version of climate change deniers.

The scientific consensus is based only on evidence. Not politics. Not your snowflake opinion. And certainly not on your cherry picked junk science.  The scientific consensus is the collective opinion and judgement of scientists in a particular field of study. This consensus implies general agreement, and if there is disagreement, it is limited and generally insignificant.

Moreover, a consensus is not permanent, because, as I’ve said a number of times, science is not a dogma. If contradictory evidence arises, of the same quality that formed the original consensus, then the established concord could fall apart, or move to a different one. Remember, all science is provisional – if the evidence changes, the consensus changes.

So, the GMO scientific consensus is based on mountains and mountains of evidence, reviewed by the best scientific bodies in the world. These are the world’s leading scientists, individuals with expertise in agriculture, genetics, biotechnology, and other related fields, who have come together to review that data, and, eventually come to a consensus that appeals to the broadest swath of scientists.

Of course, I’ve written about the GMO scientific consensus many times. Reading comments to those articles are always amusing. In the past, I generally relied on a couple of august scientific bodies for this consensus, but I always get the comment, “yeah but they’re bought off by Monsanto, it only represents a couple of countries,” or any number of other logical fallacies. Thanks to an exhaustive list produced by the Credible Hulk, it’s time to review all of the world’s science organizations’ statements on the GMO scientific consensus. Spoiler alert – there is no consensus that will state GMOs are evil, dangerous, or cause us to fall over dead because corn is growing out of our brain.

Just to be perfectly clear, the term GMO also encompasses other terms like genetically engineered or genetically modified foods. There are no differences between these various terms for these foods. Furthermore, the scientific consensus includes two separate, but related claims:

  1. All GMO crops, that were developed using modern genetic engineering processes and that are approved for commercial use by national regulatory bodies, are as safe to consume and as safe for the environment as the corresponding non-GMO counterparts.
  2. Modern genetic engineering would be no more likely to cause unpredicted dangers than would other methods of changing an organism’s genome (for example, selective breeding, radiation mutagenesis, polyploidy or wide cross hybridization) which have been employed in agriculture for over 10,000 years. And we simply reject the naturalistic fallacy, which some use to claim that “natural” changes to the genome are inherently “better” than genetic engineering.

Girl Scout cookies and GMO – subtly pushing an anti-science agenda

Girl Scout cookies and GMO

Of all the icons of American life, buying Girl Scout cookies is one of the annual obligations of life. Americans buy these cookies from parents selling for their daughters, from uniformed Girl Scouts in front of the grocery store, or from a family member. I can’t wait for my annual infusion of Samoas, the Girl Scout’s take on the macaroon. Caramel and coconut – how could we go wrong? Well, apparently, I need to spend more time to consider the issue of Girl Scout cookies and GMO ingredients.

To be honest, I’m more concerned about the calories in each. But here we are.

Late last year, The Girl Scouts of the USA made an announcement in regarding Girl Scout cookies and GMO products:

At the current time, there are genetically modified agricultural crops (GMOs) in some Girl Scout Cookies based on a range of market-related factors and depending on specific cookie recipes. In some markets, the specialty-ingredient Girl Scout S’mores sandwich cookie baked by Little Brownie Bakers is made with ingredients that are verified as not containing genetically modified organisms. Girl Scouts recognizes that many people have concerns regarding GMO ingredients, and we monitor member and consumer opinion on this matter while simultaneously addressing industry trends, scientific trends, and, of course, consumer preference.

Sadly, the Girl Scouts have decided to cave in to the demands of certain groups that GMOs bring some sort of harm to consumers. Of course, the usual anti-science groups jumped into the fray. March Against Monsanto, a group that ticks off the most of the junk science checklist with their anti-GMO, anti-vaccine, and anti-fluoridated water arguments, were ecstatic with the announcement. They chimed in that,

There was a time recently in the United States when Non-GMO and organic packaged foods were surprisingly rare, so much so that choice was a virtual non-entity and entire communities of people have no access to non-GMO options.

But now, non-GMO has officially gone mainstream: one of the country’s most recognized institutions, the Girl Scouts of the USA (formerly known as America) has announced its first-ever (officially speaking, anyway) non-GMO cookie.

You can almost see the glee dripping from the announcement. Once again, let’s take a look at Girl Scout cookies and GMO safety. This change happened because of a lot of noise that signified nothing. Time to examine it again.

The breadth and depth of vaccine research

I have frequently stated that the breadth and depth of vaccine research, which provides solid evidence on the safety and effectiveness of vaccines, overwhelms the misinformation, logical fallacies, and conspiracies pushed by the Society for Promotion of Vaccine Preventable Diseases (that is, the antivaccine cult).

In other words, there is so much evidence, published in generally respected, high quality journals, that it is the basis of a pure, 24-karat gold scientific consensus about vaccine safety and effectiveness. Using just one search parameter, vaccines + efficacy + safety, there are over 4200 articles published over the past 55 years on vaccines. Other search parameters show even more results.

As I’ve said time and again, the only thing that matters to science is the quality and quantity of repeated evidence derived from a broad range of different studies. We’ve got that. Continue reading “The breadth and depth of vaccine research”

Poll–choose your favorite scientific consensus

scientific consensus

I’ve written a lot about the scientific consensus, which is the collective opinion and judgement of scientists in a particular field of study. This consensus implies general agreement, and disagreement is limited (sometimes from individuals who are not experts in the field) and considered insignificant.

The scientific consensus is powerful, and can only be refuted by evidence. Not debate. Not belief. Not flipping a coin.

So here are some of my favorite scientific consensuses (yes, that’s the plural, as far as I can tell). Which one(s) do you  accept? Vote early, vote often.

Google includes trust for medical website rankings


There are many times I have joked that pseudoscience pushers got their education from the University of Google–that is, these individuals think that they are PhDs or MDs  based on an hour of googling a question about science or medicine, then reading some of the results from the search. Most people keep the default 10 hits per page, so frequently only those first 10 hits are read.

Too many people use Google as their definitive scholarly source of information on controversial and scientific topics. Sometimes these researchers only read the 156 character meta-description, the short blurb of an article that you see in Google search results, before deciding to read it or not.

This is not the way to critically analyze information.

What does science say about GMO’s–they’re safe

The science deniers of the world, whether they deny evolution, global warming, vaccines, or GMO safety, spend their time inventing pseudoscience to support their beliefs and claims. As I have written previously, “Pseudoscience is easy. It doesn’t take work. It’s the lazy man’s (or woman’s) “science.” But it has no value, and because it lacks high quality evidence in support of it, it should be dismissed, and it should not be a part of the conversation.”

Alternatively, real science is really hard. And it takes time. And it’s based on high quality evidence. And it is repeated. And it is almost always published in high quality journals. As I’ve said a thousand times, real science takes hard work and is intellectually challenging. You just don’t wake up one day and say “I’m a scientist.” No, it requires college, graduate school, teaching, working in world class laboratories, publishing, defending your ideas to your peers, and one day, if you don’t stop, you will be an authority in your little field of science.

The anti-GMO crowd is mostly lazy. They have this luddite belief that all technology is bad, but have absolutely no evidence to support it. Sure, they pick out one or two poorly done articles and then shout for all the world to hear “GMO’s are dangerous to…bees, humans, babies, whales, trees” over and over and over again.  Yet what do the GMO refusers really bring to the table?  Continue reading “What does science say about GMO’s–they’re safe”

No more “debates” about GMO safety–thanks to trillions of data points

GMO-protestAs I’ve written a few hundred times before, there’s really no such thing as a “debate” in science, at least in the sense that two sides argue in front of the public, and then there is vote on who is “right” or “wrong.” All that matters in science is the quantity and quality of evidence, that’s it. Yes, sometimes scientists do argue about evidence, but that’s usually done in peer reviewed articles, notes, and other forms of communication. It is mostly civil. And eventually, the evidence drives to a consensus.

Only to the public is there a delusion that there are debates on science. You might think there are debates about anthropogenic global warming, evolution, vaccines, HIV/AIDS, and GMO/biotechnology, but there really isn’t. Scientists aren’t sitting in bars across the world throwing bottles of beer at each other because everyone is divided between pro and anti-GMO. Because that’s just plainly not happening.

When I read that 97% of climate scientists support the fact of global warming or that 99.4% of natural scientists agree with the fact of evolution, it implies that there’s some sort of vote. But if there were, it would be, what we call in US elections, a landslide. But in reality, scientists come to a consensus about broad principles over time, and that is based on published evidence, not logical fallacies or bad data.
