A majority of establishment academic climate scientists have succumbed to a virulent infectious disease - the CO2 Derangement Syndrome.
They have an inability to recognize the most obvious Millennial and 60 year emergent patterns which are trivially obvious in solar activity and global temperature data. This natural climate cycle variability appears to them frightening and emotionally overwhelming. Critical thinking capacity is badly degraded.
The delusionary world inhabited by the eco-left establishment is epitomized by Harvard's Naomi Oreskes science-based fiction, " The Collapse of Western-Civilization: A View from the Future" Oreskes and Conway imagine a world devastated by climate change. Intellectual hubris, confirmation bias, group think and a need to feel at once powerful and at the same time morally self-righteous convinces them that anthropogenic CO2 was the main climate driver. This led governments to introduce policies which have wasted trillions of dollars in a quixotic and futile attempt to control earth's temperature by reducing CO2 emissions.
The origins of this disease can be traced to Ehrlich's 1968 book "The Population Bomb". He said:
