Professor Bindoff is a physical oceanographer in the Institute for Marine and Antarctic Studies (IMAS). His focus is on detecting and understanding the causes of change in the oceans. He was the coordinating lead author for the Fourth and Fifth Assessment Reports from the Inter-Governmental Panel on Climate Change. He led the oceans chapter (2007) and the detection and attribution chapter (2013). Nathan is one of just a few scientists who have been a coordinating lead author twice and contributed to the IPCC winning the Noble Peace Prize in 2007, shared with Al Gore. His research has involved documenting the first evidence for changes in the Indian, North Pacific, South Pacific and Southern Ocean's, and the earth's hydrological cycle from ocean salinity. His most recent work is on documenting the decline in oxygen content of the oceans and projecting the future climate over the Australian continents and impacts. All of these global changes have been attributed to human activity.
