There was a Forbes article[1] last year that linked to a number of studies. If you're looking for a less journalistic take and want to poke around with the data/studies yourself check out GENERA[2] (a database of peer reviewed GMO studies).
FiveThirtyEight did a good piece on the gap between "what the public thinks and what scientists know" and saw the widest margin in the subject of GMO safety[3]. A recent NYT op-ed explains some of the benefits of GMOs and what caused the author to change their stance[4].

Herbicide-resistant crop technology has led to a 239 million kilogram (527 million pound) increase in herbicide use in the United States between 1996 and 2011 http://www.enveurope.com/content/24/1/24
But a new study released by Food & Water Watch yesterday finds the goal of reduced chemical use has not panned out as planned. http://www.forbes.com/sites/bethhoffman/2013/07/02/gmo-crops...

The same thing is happening to other herbicides, just slower, because they weren't used as much. They weren't used as much because they were replaced with glyphosate.
I recall about over 15 years ago how all my peers and many experts in the industry said the "consensus" on building web services was to use SOAP BPEL and develop using waterfall methodologies. At that time Agile development and REST services might have been considered quackery.
One of the links in my comment was to GENERA[1], a large database of peer reviewed GMO studies, feel free to "dig" away.

First of all that's just generic use of the word consensus[2], not quite the same as the concept of scientific consensus[3]. Scientific consensus can certainly change over time (you wouldn't want science to just assume whatever if previously thought was right, would you?) but that doesn't mean we should dismiss the current collective judgment of scientists because they might change their position X years from now.

What we think of scientific consensus may not be what it actually is in reality. https://plus.google.com/+ChrisReeveOnlineScientificDiscourse...
