John A. Church
Dr. John A. Church (born 1951) is an expert on sea level and its changes. He was Co-convening Lead Author (with Jonathan M. Gregory) for the Chapter on Sea Level in the IPCC Third Assessment Report and a member of the Joint Scientific Committee of the WCRP. He is currently a project leader at CSIRO .
Since that time Dr. Church has led a number of programs with CSIRO Division of Oceanography and was Program Leader of the Oceanography Program (now non-existent), Australian National Antarctic Research Expeditions; former Project Leader, Leader, Southern Ocean Processes Project (now non-existent), CSIRO Division of Marine and atmospheric Research, Polar Waters Program (now-non-existent), Antarctic Climate and Ecosystems Cooperative Research Centre. On an international level, Dr. Church has been the Principal Investigator for the NASA/CNES TOPEX/Poseidon Extended Satellite Mission (which is now dead) since 1996. Dr. Church is a Member of the Australian Institute of Physics.
Currently, Dr. 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)

- Sea levels are expected to rise as a result of global warming with adverse effects on many people living in coastal areas, although the patterns may not be uniform around the globe.
- Sea-level rise projections for 2100 are several tens of centimetres above 1990 levels but beyond 2100 sea level will continue to rise for centuries after greenhouse gas concentrations have stabilised.
