If Some A are B

Not to belabor the point, and as a correction to my initial post,
If some A are B
and C is A
the statement "C is B" is an invalid conclusion and therefore not-true given the premises. It cannot be true without changing the premises (e.g. change "some" to "all"). That C is B may be true due to some other factors is possible, but does not logically follow from the premises you set out.

The point is that, because you position the argument as a test of deductive (i.e. syllogistic) reasoning and then promote a non-valid conclusion, people who may be sympathetic to the point of the article (i.e. that more study is warranted WRT the Kilimanjaro glacier) are instead diverted into either arguing about logical fallacies or dismissing the point altogether as illogical bunk (which it is not).
