Sea Level Rise

With the majority of our population located in coastal zones, the subject of sea level rise is a significant source of concern for policy makers, planners and residents. The following links will guide you through a range of web resources, providing insight into the science and issues of sea level rise.

  1. Why does sea level change? – A CSIRO Flagships website with lots of good information. Be sure to check projections, impacts and measurements.
  2. Post IPCC AR4 Sea Level Rise Briefing - from the Antarctic Climate and Ecosystems CRC
  3. Facts about ice sheets -from the Department of Environment, Water, Heritage and the Arts Australian Antarctic Division
  4. The Contribution of the Cryosphere to Changes in Sea Level -University of Colorado National Snow and Ice Data Center
  5. Coastal indicators - Australian Online Coastal Information
  6. Rising tide - on assessing the risks of climate change in low elevation coastal zone

After taking the time to read through these resources you will be able to answer the following questions:

  • What are the three primary contributing factors to rising sea level cited in the IPCC Third Assessment (TAR)?
  • What do recent altimeter measurements indicate about changing sea levels?
  • The upper limit of AR4 sea level projections was based on the ‘high range’ A1FI scenario; however, since 2004 global emissions of greenhouse gas have exceeded those built into this scenario. What might this mean for future projections of sea level rise?
  • Do ice-shelves contribute to sea level rise? If not, why not?
  • How often can we expect extreme sea level events to occur around the Australian coastline with a moderate sea level rise?
  • What are some of the critical issues for populations located in low elevation coastal zones?
