That fits the definition of the word perfectly. Also, the author cites a study from Unesco that confirms his emotionally charged anecdotes. Data alone will rarely spur people to action.
1. Citing two data point among paragraphs of anecdote is cursory.
2. Opinion pieces (should) mean they have a declared persuasive goal, not that all forms of rhetoric are acceptable. The word "opinion" is not a license to argue from astrology.
