The underlying question "is gender biasing the production of scientific knowledge and scientific narratives?"

Not quite -- your question belongs to the field of sociology of science, more or less, and this is a paper in an Earth sciences journal. The authors don't ask questions about gender bias, they specifically propose a "feminist glaciology framework", in part because they unconditionally assume that this bias exists and severely impacts the study of glaciers.

gets us no closer to the truth

I see no evidence whatsoever that this paper has any interest in what you or I might consider "truth" of the scientific kind.

I don't know if such disciplines are well-known academic jokes or not.

It depends on who you ask :-/
