Barry Brook

Brook's advocacy for nuclear power has been challenged by opponents of nuclear industries, including environmentalist Jim Green of Friends of the Earth. Brook has been similarly critical of anti-nuclear activists and in 2015 described the Greens political party (SA Branch) and Australian Youth Climate Coalition as "sad" and "increasingly irrelevant" after they expressed their opposition to nuclear industrial development.

In February 2015, the South Australian Premier Jay Weatherill announced the Nuclear Fuel Cycle Royal Commission to investigate the potential for an expanded role for the state in all aspects of the nuclear industry (mining, enrichment, reprocessing, waste management and nuclear electricity generation). Brook described the announcement as "real progress." In April 2015, Brook was one of five members appointed to the Expert Advisory Committee of the Royal Commission, along with Ian Lowe, SA Chief Scientist Dr Leanna Read, Timothy Stone CBE and John Carlsson, to provide high-level advice. Commissioner Kevin Scarce said "The members of this Committee have been chosen to ensure that the Commission receives a broad range of advice and reflects the diversity of views that the community holds,"

Brook, along with 17 other environmental scholars, released An Ecomodernist Manifesto in April 2015, which represented a declaration of principles for new environmentalism. The summary of the manifesto says: "We offer this statement in the belief that both human prosperity and an ecologically vibrant planet are not only possible, but also inseparable. By committing to the real processes, already underway, that have begun to decouple human well-being from environmental destruction, we believe that such a future might be achieved. As such, we embrace an optimistic view toward human capacities and the future." It was described by Eduardo Porter of The New York Times as a "...new strategy [that], of course, presents big challenges".

In an open letter of December 2014 that he led, 75 leading scientists urged environmentalists to set aside their preconceptions about nuclear power. They express their support for an article titled Key role for nuclear energy in global biodiversity conservation., written by Brook, stating that it provided "strong evidence for the need to accept a substantial role for advance nuclear power systems" as part of a range of sustainable energy technologies. "Much as leading climate scientists have recently advocated the development of safe, next-generation nuclear energy systems to combat global climate change ... we entreat the conservation and environmental community to weigh up the pros and cons of different energy sources using objective evidence and pragmatic trade-offs, rather than simply relying on idealistic perceptions of what is 'green'."

In 2011, Brook co-authored a "Nuclear Series" of articles for the South Australian Chamber of Mines and Energy with Ben Heard, and Australia's nuclear options, a policy perspective document for CEDA (Committee for Economic Development of Australia). Brook contributed the first of five chapters to the latter, entitled The role of nuclear fission energy in mitigating future carbon emissions. The other chapters were written by fellow advocates Anthony Owen (UCL), Tony Wood (Grattan Institute), Tony Irwin (Engineers Australia) and Tom Quirk (a nuclear physicist).

In the 2010 book Why vs. Why: Nuclear Power Barry Brook and Ian Lowe discuss and articulate the debate about nuclear power. Brook argues that there are seven reasons why people should say "yes" to nuclear power:

Brook established the popular blog Brave New Climate in 2008 and posts regularly. Guest bloggers also feature and BNC occasionally republishes articles by authors who share Brook's interests. Brook describes the website as catering "for people concerned about mitigating climate change, protecting biodiversity, whilst also enhancing human well being and growing our civilisation."

Brook has held positions on a number of advisory boards, committees and councils. These include the Australian Research Council, South Australia's Premier's Climate Change Council (2007-2010), the Premier's Science and Research Council, the Nuclear Fuel Cycle Royal Commission, the International Awards Committee of the Global Energy Prize, and the advisory board of the Barbara Hardy Institute at the University of South Australia. He also advocates for the not-for-profit Science Council for Global Initiatives.

Barry William Brook (born 28 February 1974 in Melbourne, Australia) is an Australian scientist. He is an ARC Australian Laureate Professor and Chair of Environmental Sustainability at the University of Tasmania in the Faculty of Science, Engineering & Technology. He was formerly an ARC Future Fellow in the School of Earth and Environmental Sciences at the University of Adelaide, Australia, where he held the Sir Hubert Wilkins Chair of Climate Change from 2007 to 2014. He was also Director of Climate Science at the Environment Institute.
