Nobody really ever said the world will end in 5 years.

The message has basically always been "the climate is fragile and we're adding energy to that system, which will cause change in the climate"

The whole "the world will end in 5 years" is a really lame reaction that dismisses the messaging on purpose. It's what people use when they don't want to say, "I don't care" because saying that makes people feel/look bad or because they are "anti-hippie" or whatever phrase we wanna use.
