John Costella, a former physicist turned data scientist and software engineer, recounts how watching climate-skeptic films, then reading leaked “Climategate” emails in 2009, changed his trust in climate science. He edited, annotated, and published selected emails, producing a 180-page color book printed by Australia’s Lavoisier Group, arguing the core group was small, politicized, PR-driven, and statistically sloppy, with bullying (including by Michael Mann). He says inquiries cleared wrongdoing but standards were low for policies with huge economic stakes. He then warns AI is already conscious and smarter than him, replacing white-collar jobs, inflating bubbles, and likely triggering a major economic crash soon, with unclear survival strategies.
