Paul,

Thanks for helping me to make my case!

The point is that you DON'T believe that smoking causes lung cancer on
the basis of scientific evidence that you understand and evaluate,
because you are not a scientist. You believe it because it is "common
sense" (which is irrelevant, for it merely boils down to the fact that
it seems to you to be true) and because the experts tell you it is
true. You still haven't shown a difference between the case of smoking
and human carbon consumption. Let's look more closely at some of the
BAD arguments you give below for the supposed difference.

Two clarifications first. My point was that unless you are an actual
scientist, it is almost impossible to make judgments about scientific
claims on evidence alone. In most cases, understanding the evidence
would require a high level of expertise. This is why scientific
beliefs should be based on testimony, the testimony of experts in the
field. My general claim was that there is NO basis to dismiss one set
of scientists (climate scientists, say) yet not dismiss others as
well. In my previous post, I happened to mention scientists who
specialize in lung cancer research but below I mention others since
they are helpful in showing flaws in your reasoning.

Also, you might wonder how I'm qualified to speak about such matters,
given that I'm not a climate scientist either. But I'm not making any
claims about the climate. I just trust what the climate scientists
tell me for reasons given. I'm making claims about your arguments and
when it comes to judgments about the strengths and weaknesses of
arguments -- the area of logic and the broader area of epistemology --
there is NO ONE living on the Palouse who is more qualified than I am
(although there are a few people who are as qualified).

The points in (1) are irrelevant and were addressed above. In the
1950s smoking seemed to be a healthy activity and was promoted as
such. Common sense turned out to be wrong. Common sense is never a
reason for holding scientific beliefs.

Wrt (2), I'd be willing to bet that there are climate scientists
working on these very questions. In any event, I'm not sure what
evidence you have to say otherwise. I tend to leave it to scientists
to determine what kinds of studies they should or shouldn't be
concerned with in order to support their claims. Since you are not a
scientist, these points are meaningless.

For point (3), it is true that the climate is complex. But the
universe is even MORE complex. To the extent that this gives you a
reason to dismiss climate science it should give you EVEN MORE reason
to dismiss all of physics for both the micro-level of the universe and
the macro-level of the universe are FAR MORE complex than the earth's
climate. This is just a general skeptical argument that applies to
almost ANY area of science. Why accept it wrt climate science but not,
say, cosmology? Why believe anything that Stephen Hawking says, for
instance? Do you know how much MORE complicated the whole frickin'
universe is when compared with the earth's climate? This is an absurd,
BAD, and irresponsible argument.

I've responded to arguments like those in (4) and (5) before but it
hasn't seemed to sink in yet. Whether or not a scientist has an agenda
is IRRELEVANT. What matters is the EVIDENCE he or she has in support
of the claims made. Suppose you find out that 99% of scientists who
study the links between smoking and lung cancer went into the field
for emotional and irrational reasons -- suppose, say, that members of
their family died of lung cancer. That would be irrelevant and
shouldn't cause you to dismiss their findings. ALL that is relevant is
the epistemological quality of the evidence, which can be judged in
objective ways.

If your argument were sound, it should give people reason to dismiss
EVERYTHING you say because you clearly have an agenda. You can't tell
me that your concern with the issue of global warming is independent
of your political views or your personal habits, that it is solely
motivated by the desire for objective truth and nothing more. This
very argument undermines everything you say on Vision 2020 since all
of it is in keeping with your own political viewpoints, or "agenda."
But people shouldn't dismiss your views merely because you happen to
be interested in politics. They should judge your views on the basis
of the evidence you provide in support of the claims that you make.
They shouldn't make sweeping generalizations about your claims either;
they should evaluate each argument individually.

If your argument were sound, we should dismiss ALL sciences related to
human heath, since they are all motivated by the subjective desire to
help human beings extend their lives and improve the quality of their
lives. Likely anyone working in the area of cancer research is
motivated in part by the selfish desire to become THE person that
finds the cure for cancer. That is irrelevant. This is another general
skeptical argument that (if sound) should cause you to dismiss much
more than climate science.

ALL scientific claims should be judged by the merits of the evidence
given. Personal facts about the scientists are ALWAYS IRRELEVANT.
People tend to choose their vocations for personal reasons, not
because of a desire to seek objective truth. Scientists are no
different in this regard.

Best, Joe
