Here’s the straight scoop. Conclusion…
The bottom line? No one is certain what’s going on, but a lot of the theories can’t – by themselves – explain everything we’re seeing. More important, the situation hasn’t yet risen to the level of a catastrophe (except, sadly, for some of the affected beekeepers). If the same thing keeps happening every winter for another decade or so, then we might really start worrying. But for now, classifying this as a “problem with potentially severe economic impact should it persist” would be a more realistic assessment.
