I think the author of the article misused his language (although the intent was clear enough nonetheless) but he was not what was being reported on in the article but the scientific findings reported in the journal Nature and elsewhere were.
While you could have mentioned this minor error in passing, you did not address anything of importance cited in the article about the effects warmer winters were having on flora and fauna.
This minor mistake is not to be taken lightly, you say? You are joking right? The article scientific points were totally ignored by you. Totally!
This makes your comment absurd to the point of being Monty Pythonesque where someone focuses on a minor error and makes a big deal about it while completely ignoring the main points of the article.
