Climate change is certainly real and certainly anthopogenic. The problem is that denial is not about the science; it's a religious matter. The religion is that of endless GDP growth and our 'right' to enrich ourselves.
This religion is a childish fantasy, an addiction. Until despair finally drives them to accept their affliction and deal with it, alcoholics will resort to all sorts of tactics including denial, secrecy, outright lying, sneering, blame deflection, resentment, anger and even violence.
We are now dealing with an addiction very much like alcoholism. Except that right now pretty much the entire global population are fossil-fuel addicts in denial, and the violence is against their kids' future.
“International research team projects that, by 2100, one-third of the world’s population could be living outside of the “human climate niche” representing tolerable surface conditions.”
