What about all the trained professional climatologists pleading for the last few decades for the governments of the world to change their policies? Is that mass hysteria as well?

So if one's standpoint is ignored and "noble" enough, it is acceptable to talk children into anxiety disorders so that these noble ideas will be acted upon? I find this morally questionable, but that's just me.

Don't worry the anxiety is only there as long as crisis hasn't hit. Then anger takes over.

You brought the children into the argument. Until then it was Jordan Peterson vs climate science. Leave the children outside the debate for now. You're trying to use them as an example in much the same way that many people will bring up "think of the children". Jordan Peterson needs to argue the points raised by the climatologists.

> the kids marching in their little organised-by-adult-pied-piper protests suffer from a form of induced mass hysteria

You are making a good example of a political statement dressed as a scientific truth.

Similarly to ideas like https://en.wikipedia.org/wiki/Drapetomania and https://en.wikipedia.org/wiki/Phrenology, masquerading one's own ideas behind scientific-sounding words is how a scientist loses credibility.
