Bill Hare

Bill Hare is a physicist and climate scientist with 30 years’ experience in science, impacts and policy responses to climate change and stratospheric ozone depletion. He is a founder and CEO of Climate Analytics, which was established to synthesise and advance scientific knowledge on climate change and provide state-of-the-art solutions to global and national climate change policy challenges.

Bill has contributed actively to the development of the international climate regime since 1989, including the negotiation of the 1992 UN Framework Convention on Climate Change, the 1997 Kyoto Protocol, and the Paris Agreement in 2015. Throughout this time supported international and regional scientific assessment processes, including the IPCC, in different capacities to the present time.

He was a Lead Author for the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report, for which the IPCC was awarded the Nobel Peace Prize in 2007. He led the influential World Bank Turn Down the Heat reports series in 2013-2014, and has authored, or co-authored, many peer-reviewed articles in leading academic journals including Nature Climate Change, Nature, Climatic Change, Regional Environmental Change, and Climate Policy.

Bill has regularly advised and presented science and policy assessments to Ministers and Heads of Government from the most vulnerable countries. One of the key projects he is directing at present is the IMPACT Project, which is developing new scientific tools to help small island states (SIDS) and the least developed countries (LDCs) in West Africa respond to the impacts of climate change, as well as providing scientific support for delegations from these countries in the international climate negotiations implementing the Paris Agreement. Bill has been described as “the physicist who has become a go-to climate adviser for dozens of poor nations” and supports and advises ministers from Small Island Developing States and Least Developed Countries in the context of the UNFCCC climate negotiations.

In 2022, Bill was invited by the UN Secretary General to participate in the UN’s High-Level Expert Group on the Net-Zero Emissions Commitments of Non-State Entities, launched in March. The Group is working to develop stronger and clearer standards for net-zero emissions pledges by non-State entities to ensure accountability and deliver immediate climate action.

He is also one of the leaders of the Climate Action Tracker, recognised as one of the most credible sources of information on national and global action on climate change.

Bill is a graduate of Murdoch University in Western Australia, now Adjunct Professor, Murdoch University, School of Engineering, Perth Western Australia and a visiting scientist at the Potsdam Institute for Climate Impact Research.
