Climate change communication In the 1990s, Flannery observed a change in the elevational range of trees while doing fieldwork in New Guinea, and realised it was likely to be a climate change impact. He subsequently began working on climate change more seriously and shifted to campaigning and publicly communicating about climate change from the 2000s. Flannery's prominence in raising awareness around the subject, and efforts to oppose climate change scepticism, have occasionally attracted hostility from the media. Some of Flannery's academic peers were also initially critical of Flannery for speaking outside of his primary area of expertise. When discussing this in 2009, Flannery said that climate change science was a less established field earlier in his career and experts from multiple fields had shifted to respond to the issue, and said he feels publicly funded scientists are obliged to communicate their work and be vocal on important issues. In 2015, the Jack P. Blaney Award for Dialogue recognized Flannery for using dialogue and authentic engagement to build global consensus for action around climate change. As of 2021, he had attended six United Nations Climate Change conferences in official government roles and as an observer. In 2002, Flannery was appointed as chair of South Australia's Environmental Sustainability Board and was an advisor on climate change to South Australian Premier Mike Rann. He was a member of the Queensland Climate Change Council established by the Queensland Minister for Sustainability, Climate Change and Innovation Andrew McNamara. He was chairman of the Copenhagen Climate Council, an international group of business and other leaders that coordinated a business response to climate change and assisted the Danish government in the lead up to COP15. Flannery has frequently discussed the effects of climate change, particularly on Australia, and advocated for its mitigation. During the devastating Black Summer bushfires of 2019–20, Flannery frequently appeared in the media to discuss the links between climate change and the unprecedented bushfires, stating, "I am absolutely certain that [the bushfires are] climate change caused." Climate Commission In February 2011, it was announced that Flannery had been appointed to head the Climate Commission established by Prime Minister Julia Gillard to explain climate change and the need for a carbon price to the public. The commission was a panel of leading scientists and business experts whose mandate was to provide an "independent and reliable" source of information for all Australians. Following the election of
