John A. Church

Dr John A. Church 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 [http://www.acecrc.org.au/drawpage.cgi?pid=programs&sid=sea_level_rise&aid=797213] .

Biography

Dr. Church is a graduate from the University of Queensland with a BSc in Physics. He later obtained a Doctorate of Philosophy in 1979.

Since that time Dr Church has worked on and 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 atmospherec 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)

Quotes

* "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."
