John Alexander Church AO (born 1951) is an expert on sea level and its changes. ^[1] He was co-convening lead author (with Jonathan M. Gregory) for the chapter on Sea Level in the IPCC Third Assessment Report. He was also a co-convening lead author for the IPCC Fifth Assessment Report. He is a member of the Joint Scientific Committee of the WCRP. He was a project leader at CSIRO, ^[2] until 2016. He is currently a professor with the University of New South Wales' Climate Change Research Centre. ^[3]

Biography

Church graduated from the University of Queensland with a BSc in Physics in 1972. He obtained a Doctor of Philosophy in 1979.^{[ citation needed ]}

Church has led a number of programs, including: CSIRO Division of Oceanography; Program Leader of the Oceanography Program of the Australian National Antarctic Research Expeditions; Project Leader, Southern Ocean Processes Project; CSIRO Division of Marine and atmospheric Research, Polar Waters Program, Antarctic Climate and Ecosystems Cooperative Research Centre. On an international level, Church has been the Principal Investigator for the NASA/CNES TOPEX/Poseidon Extended Satellite Mission.^{[ citation needed ]}

Currently, Church is chair of the scientific committee of the World Climate Research Programme studying sea-level rise, and is leader of the Sea level Rise Project at the Antarctic Climate and Ecosystems Cooperative Research Centre. (2007)^{[ citation needed ]}
