I am a scientist and have published hundreds of refereed journal articles myself.  The news story addresses ordinary folk who will never read the journal article as it costs money to read unless one is a member of the publishing society or a works at a University.  Ordinary people will react to the story as if it was science but it is not.  Even a news story regarding science must state the primary finding and give reference the evidence that led to the scientific conclusion.  There is no evidence whatsoever that the reduced food supply is caused by global warming.  There are standards of science that must be adhered to.  I suspect from your comments that you are a warmer, i.e. member of the warmer religion.  Therefore any adverse result cited regarding warming must be correct in your mind, right?  Its settled science after all.  It is nice to live in a simple world.  True scientists wake up every day wondering if their beliefs are wrong.
