I think that, if people who believe in climate change want to be convincing, it would be more effective to avoid blaming specific instances of weather on climate change without strong justification. Especially when the weather isn’t even abnormal.
Los Angeles, especially inland and in the valley, is hot in the summer. It was hot in the summer 30 years ago and it’s still hot in the summer. It’s the typical hot season right now, and the valley appears to be only slightly above season average temperatures today, and coastal LA seeks be slightly cooler than average. Apparently it will be unseasonably cool in a couple days.
