Intergovernmental Panel on Climate Change (IPCC)

Director for the UPNG Centre for Climate and Sustainable Development Professor Chalapan Kaluwin will be the moderator of the panel discussion.

The focus for the panel discussion on this Climate Change Report will be on the physical science of climate change, covering Pacific climate occurrence including temperature rise, rainfall, marine heatwaves, tropical cyclones, sea level rise, ocean acidity and coastal flooding.

The long-held view has been that the world's seas would rise by a maximum of just under a metre by 2100.

This new study, based on expert opinions, projects that the real level may be around double that figure.

This could lead to the displacement of hundreds of millions of people, the authors say.

The question of sea-level rise was one of the most controversial issues raised by the Intergovernmental Panel on Climate Change (IPCC), when it published its fifth assessment report in 2013.
