1922 Walter Lippmann kickstarted the idea of "news value" which lists criteria predicting whether an event or narrative is worth printing.

He proposed the following, and we can apply them here to compare the two types of news:

Oddity: anti-climate wins

Sensationalism: anti-climate wins

Damage: anti-climate wins

Establishment, Duration, Structure, Relevancy, Use, Prominency, Proximity: about equal

(Translations mine, couldn't find good English ones)

Thus, the result is little surprising. Still a good study, the obvious should also be proved!
