Trump campaign CEO Stephen Bannon once ran a $200 million research center in Arizona that was studying climate change.

Mother Jones reported Friday that the former Breitbart news chief was brought on to revamp Biosphere 2, a massive enclosed artificial ecosystem originally designed to test human survival in space, after the project fell into disarray. As acting director for Space Biospheres Ventures, he told CSPAN how the group hoped to transition to more Earth-bound environmental research.

"A lot of the scientists who are studying global change and studying the effects of greenhouse gases, many of them feel that the Earth's atmosphere in 100 years is what Biosphere 2's atmosphere is today," Bannon explained in a 1995 interview while sitting inside the glass structure.

"We have extraordinarily high CO2, we have very high nitrous oxide, we have high methane. And we have lower oxygen content," he said. "So the power of this place is allowing those scientists who are really involved in the study of global change, and which, in the outside world or Biosphere 1, really have to work with just computer simulation, this actually allows them to study and monitor the impact of enhanced CO2 and other greenhouse gases on humans, plants, and animals."

Bannon left the project after two years when management was transferred to Columbia University, which significantly modified Biosphere 2 to further global warming research. The University of Arizona currently owns the site.
