So these scientists think that they need to advocate for their view more than they have been advocating for their view? I'm not sure how that is even possible, but they are going to give it a whirl.
But keep this in mind. Exaggeration and unwillingness to listen to opposing points of view or science that contradicted their predisposition led them to this state. Arrogance and hubris are a bad combination, particularly when someone is trying to convince others that the sky is falling when it is, in fact, not. Warmer does not necessarily mean worse; it does mean different, and the earth has been experiencing different for as long as it has been hurtling around the sun.
