Any time there's a chance to reject science, Anthony Watts will grab it with both hands. Today he's decided to build a strawman out of bees. He's found a rather shallow article at Washington Post, which looks to me to have a lot wrong with it. The article was about how beekeepers have managed to rebuild the honey bee population in the USA. It's not yet back to its heyday of 1990, however it's increased from the low days of 2006 by about 20%. Close to the end of the article, a couple of economists are quoted cheerily calling the recovery "a victory for the free market", oblivious to the government support that helped address all the huge problems.
Anthony Watts' strawman
Anthony Watts wrote the headline: "Bee-pocaclypse called off, bees doing OK, global warming was never a cause" and referred to an old article from Wired. I say he referred to it, but he didn't link to it, he just copied and pasted a snapshot of the headline. That very short 2007 Wired article was about an article at Salon. That Salon article in turn was about how scientists were starting to look into the massive decline in the US population of honeybees. There were a lot of possible reasons put forward in the Salon article, but at the time (2007), all the research wasn't in.
Needless to say, Anthony Watts didn't give any insight into US honey bees. He doesn't do background research. His forte is copying and pasting slabs of text pinched from somewhere or other, putting his "claim" dogwhistle headlines on top of scientific press releases, and promoting logical fallacies and wacky climate conspiracy theories.
What caused the dramatic decline in honey bees in the USA?
It seems that there wasn't a single cause, there were a combination of factors that lead to the rapid decline in honey bee numbers. One of the main culprits was called Colony Collapse Disorder, but that also had multiple causes.
I've come across a paper by Professor May R Berenbaun, who is Professor and Department Head of the Department of Entomology at the University of Illinois at Urbana-Champaign. Her paper is fabulous. She gives a history of beekeeping going back to early innovations. As well as that she discusses how scientists got together to identify what had happened to the honey-bee population, the multiple causes of the decline, and how it has since recovered quite a lot. It's complicated. She referred to "a century of benign neglect" among other things. In recent decades there were mite infestations, which rapidly developed resistance to pesticides. In October 2006, scientists mapped the genome of the honey bee.
In 2006 Dr Berenbaun headed up a National Academy of Sciences Study Group to look into the problems with honey bees, so she knows her stuff. Colony Collapse Disorder isn't a single cause, it's the result. The causes seem to have included everything from viruses and other pathogens (eg various viruses carried by mite infestation) to a "staggering amounts of chemical contamination within managed hives".
Her paper is long, but it's chock full of information, entertaining and easy to read, if you are interested in learning about the US honey bee industry.
From the WUWT comments
peter is, perhaps wisely in this case, more inclined to listen to beekeepers, not the Washington Post

Comments on the article are about what I would expect. “Is to, is to, is to, a problem. I don’t care what your facts are.”
That said, there are some comments from bee keepers who say the problem is still a problem and I tend to give credence to people who actually get their hands dirty over office experts.
So I don’t know what the truth is on this.
William Grubel talks of "a parasite" - yet there are a combination of problems with honeybees:
February 17, 2016 at 4:25 pm
The answer is easy. There IS a parasite. They DO lose 30% every year. They CAN and DO compensate as a normal part of their business. What I DON’T see is any connection to global warming. Seems the alarmists have gone dark on this subject.
Bulldust is correct AFAIK. Some Australians earned a few bob sending disease-free Australian bees to the USA:
February 17, 2016 at 4:46 pm
I believe Australia is still largely or totally Varroa free. Apparently there is quite a demand for our bees.
Mark luhman just likes a good conspiracy theory:

Just like the frog die off, human had something to do with it, ecotourist and and human pet frogs help spread the fungus that killed the frogs by introducing it to populations that had not seen it before but again global warming or the use of herbicides and insecticide had nothing to do with it. The blame human first crowd pick on the the “political correct causes” while ignoring the true cause since the true cause would not advance their agenda.
dbstealey doesn't have an opinion on the subject of the article, but he knows that climate science is a hoax:

Danny Thomas says: …man always affects his (her) environment just by being in it.
Agree completely. But that isn’t the question. The question that answers the debate is this one: is dangerous AGW happening?
The answer is clearly No. We have been enjoying a true ‘Goldilocks’ climate for more than a century. Rational folks say, “Give me more!”
It’s the irrational crowd I’m worried about.
TG posts some inane "thought" that popped into his head. Nothing to do with bees.

Maybe mental illness and too many climate conferences are killing all species.
How about Warmers getting a productive job that contributes to the economy instead of condemning progress and the constant seeking rentseeking grants and handouts!!!
Most of the rest of the WUWT comments were either:
- the certain cause of the problem (usually just one) or
- one of the "climate science is a hoax" conspiracy theories.
Don't waste your time at WUWT. If you're interested in the history of bees in the USA and the causes of the dramatic drop in numbers in recent years, and the rebuilding of the honey bee population - read the article below.
