Climate change might be one explanation, but they aren;t sure.
It's just the convenient blame du jour.
Nearly every reference to global warming was followed by, "but we
don't know for sure", or something similar, so in my opinion it was
fairly objective.
My informal impression is that the scientists are roughly divided into
a bell curve of opinions on this thing.
If we examine the bell curve from the (symbolic) left to the
(symbolic) right,
we begin with one realtively small group that is completely convinced
that the climate is indeed changing and that it is due almost entirely
to human activity.
Moving slightly toward the center is a somewhat larger group that is
fairly sure that the climate is changing, and contributes much of the
change to human activity.
Almost to the middle on the left side is a larger group yet that has
observed recent data regarding climate change, has not yet reached a
final conclusion, but leans toward the notion that global warming is a
reality and recognizes that human activity could be a factor.
Just beyond the middle on the right side of the curve is a large group
that has observed recent data regarding climate change, has not yet
reached a final conclusion, but leans toward a conclusion that if
there is any warming of the planet it is likely to be inconsequential.
This group is skeptical concerning the ability of man to make any
significant impact on the climate.
Farther beyond the middle on the right side of the curve is a smaller
group that
disputes nearly all evidence that the earth is warming, and denounces
any theory that changing the mixture of gases in the atmosphere could
possibly
result in a way that the planet absorbs or retains solar energy.
Way out on the right hand edge of the curve is a very small group that
insists the climate is not changing at all, that if it ever were to
change it couldn't possibly be due, in any degree, to human
activities. Some of this group may even insist that the earth is
getting progressively colder.
I thought the scientists quoted in the article were pretty objective
about the global warming possiblity, including the guy who said "It's
still pretty difficult to separate a signal from all the available
noise".
Dead birds with empty bellies and no body fat would have to mean a
shortage of bait fish. No bait fish = no salmon. No salmon = no sea
lions, orcas, etc.
