I guess you're referring to media jumping too quickly to "bad science" for every single event of floods, drought, fires etc, therefore using fear and producing saturation in fellow citizens.
that said, I honestly have a bad time trying to figure out if there's such a thing as "too alarmist" re. claims like "one third of projected population by 2070 will live in a nearly unlivable earth" https://www.pnas.org/content/117/21/11350
