You are half-right, unfortunately. Objectively, the climate will do it's own thing. If additional carbon dioxide was to produce a slight bias towards warmer atmosphere, it could only be for the better ,we are in the grip of a prolonged ice age, and the interglacial is quite old in the tooth now. More carbon dioxide certainly helps plant life on which we all depend for our sustenance. Politically and culturally, it matters a whole lot. Progress of science caused rapid increase in world's population. This population cannot be sustained without science. In other words, at least minimal public trust in science as an institution is essential. Without this trust, we are looking at a true catastrophe. You are seeing elements of it in the current spread of old fashioned fascism, based on racism, which feeds on the mistrust of "elites" which represent the reason based governance.

Institutions of Science, all the assorted Academies, have failed catastrophically to support the integrity of Science. This threatens the very foundations of the rational governance project. This, not climate changes, is the threat. Humanity, and life on earth, were able to adjust to drastic climate changes, far greater than anything that has been happening in the present era.
