To be accurate, there are many heat waves, and it has not been established that this one in particular is in any way caused by global climate change. The best you could say is that global climate change causes more heat waves, and this heat wave is part of a trend of increasing number and severity.

It would be like saying that because increased wealth inequality drives increased crime, that every single crime report should have boilerplate at the end saying that this crime was caused by wealth inequality.

In contrast, there's only one Houthi group, and they are Iran linked, so that is a much more accurate contextualization.
