More than 80 percent of Australians live near the coast and a Climate Council report has already warned that future sea level rises could put more than $200 billion of infrastructure at risk. High quality measurements of (near)-global sea level have been made since late 1992 by satellite altimeters, in particular, TOPEX/Poseidon (launched August, 1992), Jason-1 (launched December, 2001), Jason-2 (launched June, 2008) and Jason-3 (launched January 2016). They illustrate an event that could be expected to occur at least once a year, but possibly more frequently, around the year 2100. This work was presented in Adhikari et al., GMD 2016.The simulation captures the evolution of sea level rise over the entire planet, taking into account eustatic sea level, sea level rise from perturbations to the gravity field, and sea level rise from local elastic rebound of the Earth's crust. The low scenario represents sea level rise that is likely to be unavoidable. It also considers the projected variation in the local sea-level rise rate of northern Australia. The calculated inundation is based on high tide, the Australian Height Datum and various sea level scenarios based on findings from the Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report, as shown in the below calculation. Email: enquiries@climatechange.gov.au The Australian Government has developed a series of initial sea level rise maps to illustrate the potential impacts of climate change for key urban areas. Monday to Friday 9:00 am – 6:00 pm AEDST With high rates of emissions, sea level rise would be much higher, but was unlikely to exceed 6.6 feet higher than 1992 levels. Select your local area to view future sea-level rise and climate extremes . Scientists forecast that in just the next 20 years, the sea will have risen by another 6 inches. And then there’s a new map that lets users peer 60 years into the future of North American cities. Consistent with global increases, sea levels have risen in Australia at an average rate of 2.1 mm/year over the past half century. Sea level began to rise again in the 19th century and accelerated again in the early 20th century. The ultimate goal is to identify long period sea level changes, with particular emphasis on the enhanced greenhouse effect on sea level. Sea level rise is speeding up. © 2021 Spatial Source. However, these effects are important in understanding Australian sea-level rise and its relationship to global sea level. NGIS Australia built the website based on an earlier model used to map sea-level rise in the Pacific Islands. Maps are available to show three sea level rise scenarios: low sea level rise (0.5m), medium sea level rise (0.8m) and high sea level rise (1.1m). The sea level rise values were based on Intergovernmental Panel on Climate Change (IPCC) projections and more recent science and observations. The project is designed to monitor sea level around the coastline of Australia. Layers (0) Management Regions. The project is designed to monitor sea level around the coastline of Australia. CONNECT Interactive Sea-level Rise Impact Map. Extreme sea level events (storm-driven waves and surge) also became about three times more frequent during the 20th century. Global sea level rise began around the start of the 20th century. Asia China & Japan Australia: my flood map | about | privacy Data provided by NASA Map of Australia showing sea-level change and archaeological sites for selected periods between 35,000 and 8,000 years ago. Choose Layers Manually. Inundation = Sea Level Rise Scenarios (Low, Medium and High) + High Tide + Water-Land (MSL-AHD) Offset. In June 2011 a supplement to Climate Change Risks to Australia's Coasts was released. Digital Earth Australia: Intertidal Extents Model and High and Low Tide Composites ; NationalMap – view & access Digital Earth Australia Data ; Relevant Links. Figure 1. The underlying DEMs have been mapped in great detail using airborne LiDAR at a resolution of 5 metres along Australia’s coast. Visit the Coastal Risk Australia website to see how your area might be affected. In Australia the consequences of sea level rise will include increased flooding of low-lying coastal, including tidal, areas and are likely to result in coastal erosion, loss of beaches, and higher storm surges that will affect coastal communities, infrastructure, industries and the environment.
