Formal Logic

er,
Formal Logic dictates that the validity of the syllogism is FALSE, not "Neither"

The post correctly points out that premise (A)'s lack of the category "all" means that it appropriately reads:
(A)[some] Glaciers on Earth are retreating due to global warming.

Premise (B) may stand as written:
(B) The glacier on Mount Kilimanjaro is retreating,

The conclusion (C), reading:
(C) The retreat of the Kilimanjaro glacier is due to global warming.

is logically false.

Saying
some A are B
C is B
Therefore C is A

this is the fallacy of affirming the consequent (http://www.fallacyfiles.org/afthecon.html)

while, personally, I agree that more study is needed to link (or not) the Kilimanjaro glacier to warming, it is important that arguments be presented correctly.
