Where is this Global Warming they keep talking about?
They changed it to climate change. As if it hasn't been happening since the planet formed, these poor, mentally ill people wish to take on the burden of guilt for events beyond anyone's control, with delusions of grandeur about being able to effect change and save a whole planet they have no control over.
Even worse, this mass hysteria/delusion continues to the level that it affects government policy, and perhaps, even species survivability at current technological levels.
I would prefer they simply don sackcloth and ashes and roam the planet flagellating themselves and each other. At least that would confine all but the effects of the relative trauma of witnessing such graphic behaviour to those who desire to embrace that guilt, without causing major disruptions which might cause untold misery and even the deaths of those unaffected by their psychological disorder. Institutional confinement might be even more desirable.
