Joanne Nova

Joanne Nova is an Australian science writer, blogger, and speaker. Born Joanne Codling, she adopted the stage name "Nova" in 1998 when she was preparing to host a children's television program. Nova has disputed the findings of climate science on global warming for a number of years.

Nova received a Bachelor of Science first class and won the FH Faulding and the Swan Brewery prizes at the University of Western Australia. Her major was microbiology, molecular biology. Nova received a Graduate Certificate in Scientific Communication from the Australian National University in 1989, and she did honours research in 1990, investigating DNA markers for use in muscular dystrophy trials.

For three years Nova was an Associate Lecturer of Science Communication at Australian National University. For four years, Nova jointly co-ordinated the Shell Questacon Science Circus, which operates all over Australia.

From November 1999 to February 2000, Nova was the host of the first series of Australian children's science television show Y? and worked for a short period on Space Cadets, a science fiction show by Foxtel.

She was a regular guest on ABC Radio as a science communicator,. She is a director of GoldNerds, a gold investment advice business.

As a blogger, Nova writes on the science, funding, and politics related to anthropogenic global warming (AGW). Nova had a five-part debate on AGW with Dr Andrew Glikson, first on Quadrant Online, and continuing on her own blog. In 2012, she appeared in the ABC Television documentary I Can Change Your Mind About... Climate with her partner David Evans, in discussion with Nick Minchin and Anna Rose, in which she stated that:

...carbon dioxide is a greenhouse gas and that adding more to it will warm the planet, yes, absolutely, that's all well proven solid science known for years, yes. I have no disagreement with any of that. Disagreement is with how much warming there is. Is it going to be a catastrophe or is it going to be 0.5 degrees and as far as we can see the evidence the empirical evidence, and there's lots of it, all seems to point to it being around about half a degree to maybe one degree with CO2 doubling which is not the catastrophic projections that are coming out from the climate models.
