I'm not sure there are good journalistic practice's for this yet. It takes space to properly cite that climate scientists have said that climate change has increased the intensity and frequency of these fires. Awkward too. I would like to see it settled that in short news articles, it is sufficiently settled science to simply use phrases like "climate change exacerbated wildfires" - but unfortunately, editors are still afraid of being accused of editoralizing.
Which is insane, as there are plenty of the conclusions of economists that get worked into the language without question, on far thinner support. Edit: or even pseudo-economists - I am thinking of the regular, unexplained language that equates a nations spending with a household budget, for example. That can be slipped in undefended no problem.
