You're mistaken there: "The boy who cried wolf" is about lying about there being a wolf while it isn't, not about speaking the truth but nobody wanting to listen.

It has been the warmest day in the history since anyone starting measuring, and the summer days haven't started globally yet is a pretty factual way to put it in my book

There are mountains of people doing what you do and complaining about alarmism and fear mongering and chiding people for apocalyptic predictions any time this subject comes up. I think that's worse than unhelpful, and is a disservice to everyone that lives after us. People are sounding the alarms and making dire predictions because there is so far 0 indication that as a global society we can cooperate well enough to prevent serious and irreparable harm to Earth's ecosystems and a great deal of consequent human suffering. We just barely, as a species, managed to contain ourselves well enough to not blow up in a nuclear light show. Peace is a fragile stalemate, not a lack of desire to destroy each other. If you ask me, there's no hope of an adequate change of inertia to prevent unprecedented human suffering stemming from AGW, and that's in large part because people would rather ignore it and stay comfortable. Toning down the alarmism does nothing to fix that.
