OK, let me check again the Oxford
evidence:
1. Clearness, obviousness,
2. Indication, sign; testimony, facts, in support of, (or for) a conclusion.
The printing of this dictionary is 1979
But do not get intimidated by this definition, it can be wrong.
I would analyze yours. You wrote,
> "The available body of facts or information indicating whether a
> belief or proposition is true or valid."
Let's suppose this is a good definition.
We must look for the word "true".
True,
1. In accordance with fact or reality, nor false or erroneous.
2. In accordance with reason or correct principles, or accepted standard,
rightly so called genuine, not spurious, or genuine or hybrid, or counterfeit,
or merely apparent, having all the attributes implied in the name.
Other points are not related to our argumentation.
Fact and reality is a component of our intelligence and understanding,
that be varied and somewhat in opposition for some interpretations of
reality or facts. I mean, the same facts or the same piece of reality
can have different meaning for some sample of intelligent beings.
In the history of science you can read stories about how some fragment
or reality or a set of data, had changes its meaning, because a minority,
or some individual, presented a different interpretation. After some decades
the different interpretation can be adopted as good and the old one rejected.
But the question of something being erroneous, or false, are key words around
this dispute.
Then, if we take the fragment, <In accordance with reason or correct
principles, or accepted standard>, it bring us to the question of if humans
are fallible or infallible. If we are not infallible, the questions of
reason, correct principles, and accepted standards are hanging by a very thin
thread.
This is why I do not believe in AGW. It seems to me, is not based in correct
principles, or reason, or accepted standards expect by those that are
postulating the theory.
A few days ago, someone asked in quora, (Spanish section) someone asked
"who can say is true that exist god?"
I replied that being true is a psychological estate in which a person
thinks about some statements A, B, or C that they are true. It can be true
that Jesus is the Messiah, that Krishna is the son of Brahma, that Mohammad
is the last prophet sent by Allah, etc.
It can be true that CO2 is heating the planet and we are risking the future
of the planet if we do not stop just now of burning fossil fuels. It can be
true that this is a bogus theory and AGW a pile of lies.
Then, something true or false is engraved in our brains.
Of course, by hearing repeated thousand of times the same arguments we can
believe anything is true.
But other than trivial certainties, many "evidences" are far from being...
"clear and obvious" as the Oxford says. Then, the very nature of the theory
of AGW is far from being obvious and quite clear. Not only for it is a matter
for specialists to check on them, but also because the very dubious
calculations involved present enough reasons to doubt.
Then, the "reason or correct principles, or accepted standard," that Oxford
mentioned, are valid for trivial and well tested questions, and for some
easy experiences of reality. But not for the AGW theory. Not only because
it is very new, and in the limits of our confidence, but also because some
intelligent people are rejecting the theory.
But... if the government is paying you to develop this very theory, nobody
earning the money is going to protest. They are paid precisely for this,
to alarm the population about the consequences of burning fossil fuels.
I am alarmed as well for a different reason. This civilization is what
it looks because is burning fossil fuels. Once the fossil fuels would get
exhausted this civilization would collapse. It would be the worse Armageddon
anyone could imagine. But a warming planet? Nonsense.
