It will actually take a little while to tell if they were, in fact, crying wolf.
There is a lag between when carbon is released and when the effects of it peak. If we did stop all carbon emissions today, the effects of prior emissions would play out over the next 30ish years.
We’re injecting unprecedented amounts of thermal energy into planet-scale systems, and it is hard to predict second and third order effects.
I have kids/I really hope they were crying wolf.
