Architect, writer and urban evolutionary, with a doctorate in environmental studies, Paul Downton was born when the CO2
levels in the atmosphere were 311 ppm. It’s now 390. He spent the early
1980s reading papers on climate science and figured out, from the
evidence, that we were headed for global warming. In 1989 Paul was
instrumental in forming The Greenhouse Association of South Australia,
one of the first citizens’ organizations devoted to combating climate
change. That was 22 years ago.
